INTRODUCTION

 

Testosterone      is  a  steroid   hormone     from    the  androgen     group.   In   mammals,

 

testosterone is primarily secreted in the testes of males and the ovaries of females,

 

although small amounts are also secreted by the adrenal glands. It is the principal

 

male sex hormone and an anabolic steroid.

 

In both men and women, testosterone plays a key role in health and well-being as

 

well as in sexual functioning. Examples include enhanced libido, increased energy,

 

increased   production   of   red   blood   cells   and   protection   against   osteoporosis.   On

 

average,   an   adult   human   male   body   produces   about   forty   to   sixty   times   more

 

testosterone     than   an  adult   female   body,    but  females    are,  from   a  behavioral

 

perspective     (rather  than   from    an  anatomical     or  biological   perspective),    more

 

sensitive to the hormone. However the overall ranges for male and female are very

 

wide,    such    that  the  ranges    actually   overlap    at  the low    end    and   high   end

 

respectively.

 

PRINCIPLE OF THE ASSAY

 

The     microtiter    plate   provided     in   this  kit   has   been   pre-coated     with    an

 

goat-anti-rabbit antibody. Standards or samples are then added to the appropriate

 

                                                2


----------------------- Page 3-----------------------

microtiter plate wells with a HRP-conjugated testoterone and antibody preparation

 

specific for testoterone and incubated. Then substrate solutions are added to each

 

well. The enzyme-substrate reaction is terminated by the addition of a sulphuric

 

acid   solution   and  the  color  change    is  measured   spectrophotometrically     at  a

 

wavelength of 450 nm ± 2 nm. The concentration of testoterone in the samples is

 

then determined by comparing the O.D. of the samples to the standard curve.

 

DETECTION RANGE

 

0.1   ng/ml-25.6   ng/ml.   The   standard   curve   concentrations   used   for   the   ELISA’s

 

were 25.6 ng/ml, 6.4 ng/ml, 1.6 ng/ml, 0.39 ng/ml, 0.1 ng/ml.

 

SPECIFICITY

 

This   assay   recognizes   recombinant    and  natural  rat  testoterone.  No  significant

 

cross-reactivity or interference was observed.

 

SENSITIVITY

 

The minimum detectable dose of rat testoterone is typically less than 0.06 ng/ml.

 

The sensitivity of this assay, or Lower Limit of Detection (LLD) was defined as

 

the lowest protein concentration that could be differentiated from zero.

STORAGE

 

1.  Unopened test kits should be stored at 2-8°C upon receipt and the microtiter

 

    plate should be kept in a sealed bag. The test kit may be used throughout the

 

    expiration date of the kit. Refer to the package label for the expiration date.

 

2.  Opened test kits will remain stable until the expiring date shown, provided it is

 

    stored as prescribed above.

 

3.  A  microtiter   plate   reader   with   a   bandwidth   of   10   nm   or   less   and   an   optical

 

    density range of 0-3 OD or greater at 450nm wavelength is acceptable for use

 

    in absorbance measurement.

 

                                             4


----------------------- Page 5-----------------------

TECHNICAL HINTS

 

1.  Bring all reagents and plate to room temperature for at least 30 minutes before

 

    use. Unused wells need store at 2-8℃and avoid sunlight.

 

2.  Wash      Buffer     If  crystals  have   formed    in  the  concentrate,    warm    to  room

 

    temperature and mix gently until the crystals have compley dissolved. Dilute

 

     15 ml of Wash Buffer Concentrate into deionized or distilled water to prepare

 

    300 ml of Wash Buffer.

 

3.  To   avoid   cross-contamination,   change   pipette   tips   between   additions   of   each

 

    standard level, between sample additions, and between reagent additions. Also,

 

    use separate reservoirs for each reagent.

 

4.  When      using   an  automated     plate  washer,    adding   a  30   second   soak   period

 

    following   the   addition   of   wash   buffer,   and/or   rotating   the   plate   180   degrees

 

    between wash steps may improve assay precision.

 

5.  To ensure accurate results, proper adhesion of plate sealers during incubation

 

    steps is necessary. Sealers can not be reused.

 

6.   Substrate    Solution    should   remain    colorless  until  added    to  the  plate.  Keep

 

     Substrate Solution protected from light. Substrate Solution should change from

 

    colorless to gradations of blue.

 

                                                5


----------------------- Page 6-----------------------

7.   Stop Solution should be added to the plate in the same order as the Substrate

 

     Solution. The color developed in the wells will turn from blue to yellow upon

 

    addition   of   the   Stop   Solution.   Wells   that   are   green  in   color   indicate   that   the

 

     Stop Solution has not mixed thoroughly with the Substrate Solution.

 

Precaution: The   Stop   Solution  provided   with   this   kit  is   an   acid   solution. Wear

 

               eye, hand, face, and clothing protection when using this material.

 

OTHER SUPPLIES REQUIRED

 

     Microplate     reader   capable   of  measuring     absorbance    at  450   nm,   with  the

 

     correction wavelength set at 540 nm or 570 nm.

 

     Pipettes and pipette tips.

 

     Deionized or distilled water.

 

     Squirt bottle, manifold dispenser, or automated microplate washer.

 

SAMPLE COLLECTION AND STORAGE

 

     Serum      Use a serum separator tube (SST) and allow samples to clot for 30

 

     minutes before centrifugation for 15 minutes at 1000 x g. Remove serum and

 

     assay   immediay   or   aliquot   and   store   samples   at   -20°   C.   Avoid   repeated

 

     freeze-thaw cycles.

 

                                               6


----------------------- Page 7-----------------------

     Plasma      Collect plasma using citrate, EDTA, or heparin as an anticoagulant.

 

     Centrifuge   for   15   minutes   at   1000   g  within   30   minutes   of   collection.   Assay

 

     immediay        or  aliquot    and    store   samples    at   -20°C.   Avoid      repeated

 

     freeze-thaw cycles.

 

Note: Grossly hemolyzed samples are not suitable for use in this assay.

 

ASSAY PROCEDURE

 

Bring all reagents and samples to room temperature before use. It is

recommended that all samples, standards, and controls be assayed in duplicate.

 

1.   Set a Blank well without any solution. Add 50μl of Standard or Sample per

 

     well. Standards need test in duplicate.

 

2.   Add 50μl of HRP-conjugate to each well (not to Blank well), then add 50μl

 

     Antibody to each well. Mix well and then incubate for 1 hour at 37°C.

 

3.   Fill   each   well   with  Wash   Buffer   (about   200μl),   stay   for   10   seconds   and

 

     Spinning. Repeat the process for a total of three washes. Complete removal of

 

     liquid   at   each   step   is   essential   to   good   performance.   After   the   last   wash,

 

     remove   any   remaining   Wash   Buffer   by   aspirating   or   decanting.   Invert   the

 

     plate and blot it against clean paper towels.

 

4.   Add 50μl of Substrate A and Substrate B to each well, mix well. Incubate

 

     for    15  minutes    at  37°C.    Keeping    the   plate  away    from   drafts   and   other

 

     temperature fluctuations in the dark.

 

                                                 7


----------------------- Page 8-----------------------

5.   Add   50μl   of  Stop   Solution   to   each   well.   If   color   change   does   not   appear

 

     uniform, gently tap the plate to ensure thorough mixing.

 

6.   Determine      the   optical   density   of  each    well  within    10   minutes,   using    a

 

     microplate reader set to 450 nm.

 

CALCULATION OF RESULTS

 

Average the duplicate readings for each standard, Blank, and sample and subtract

 

the optical density of   Blank. Create a standard curve by  reducing the data using

 

computer software capable of generating a four parameter logistic (4-PL) curve-fit.

 

As an alternative, construct a standard curve by plotting the mean absorbance for

 

each standard on the y-axis against the concentration on the x-axis and draw a best

 

fit curve through the points on the graph. The data may be linearized by plotting

 

the log of the testoterone concentrations versus the log of the O.D. and the best fit

 

line   can   be   determined   by   regression   analysis.   This   procedure   will   produce   an

 

adequate     but   less  precise   fit  of  the  data.  If  samples    have   been    diluted,  the

 

concentration   read   from   the   standard   curve   must   be  multiplied   by   the   dilution

 

factor.

 

LIMITATIONS OF THE PROCEDURE

 

     The kit should not be used beyond the expiration date on the kit label.

 

                                                 8


----------------------- Page 9-----------------------

      Do not mix or substitute reagents with those from other lots or sources.

 

      It is important that the   Calibrator Diluent selected for the standard curve be

 

      consistent with the samples being assayed.

 

      If samples generate values higher than the highest standard, dilute the samples

 

      with the appropriate Calibrator Diluent and repeat the assay.

 

      Any   variation       in  Standard      Diluent,    operator,     pipetting    technique,      washing

 

      technique, incubation time or temperature, and kit age can cause variation in

 

      binding.

 

      This assay is designed to eliminate interference by soluble receptors, binding

 

      proteins, and other factors present in biological samples. Until all factors have

 

      been   tested   in   the   Quantikine   Immunoassay,   the   possibility   of   interference

 

      cannot be excluded.
