INTRODUCTION

HGH      is  Human     Growth    Hormone,     a  natural   hormone      produced    in  the

pituitary gland of the brain. HGH is considered "the key" hormone because

it controls so many functions. It's responsible for youth, vitality, energy and

all   of   the   health   benefits   we   associate   with   youth.   Dr.   Daniel   Rudman's

study     in  the   New     England     Journal    Of   Medicine     demonstrated       the

remarkable ability to reverse the effects of aging upon the human body with

the   employment   of   HGH   -   Human   Growth   Hormone!   Due   in   part   to   his

efforts, Dr. Rudmans's study saw the effects of HGH upon overweight men

between the ages of 61 and 80 years of age.

HGH reduces body fat The men did not alter their personal habits of eating,

smoking,      or  exercise,   yet  with   the  consumption      of  HGH,    they   lost  an

average of 14% of their body fat, while gaining an average of 8.8% lean

muscle mass. Their skin became firmer and they experienced a localized

increase in bone density. Over all, HgH appeared to reverse the effects of

aging by 10-20 years!!! HGH is prescribed and administered by a doctor in

the form of injections. But a nonprescription form is also available over the

counter and through mail order.

HGH   promotes   growth   in   children   and   plays   an   important   role   in   adult

metabolism.      The    body   secretes    the   hormone,     in  decreasing     amounts,

throughout      our  lifetimes.  The    amount    of  hormone     in the   body    can   be

measured by levels of IGF-1 （Insulin Growth Factor）. Growth hormone has

                                             2

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

a profound effect on all the cells of the body, more than any other hormone

because it is the cell generator.

HGH is the "master hormone" controlling many organs and body functions

and   is   directly   responsible   for   stimulating   tissue  repair,   cell   replacement,

brain   functions,   and   enzyme   function!   It’s   human   growth   hormone   that

grows the cells, bones, muscles, and organs, and it is the decreasing level

of human growth hormone after age 30 that slowly robs us of our "youth."

PRINCIPLE OF THE ASSAY

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

and    Avidin.   Standards    or  samples     are  then   added    to the   appropriate

microtiter plate wells with a biotin-conjugated HGH antibody and incubated.

Then     Horseradish     Peroxidase     （HRP）-conjugated        antibody    preparation

specific for HGH are added and incubated. 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 HGH in the samples is then determined by comparing the

O.D. of the samples to the standard curve.

DETECTION RANGE

2.5 ng/ml-50 ng/ml. The standard curve concentrations used for the ELISA’s

were 50 ng/ml, 25ng/ml,10 ng/ml, 5 ng/ml，2.5 ng/ml.

SPECIFICITY

This   assay   recognizes    human    HGH.    No  significant  cross-reactivity  or

interference was observed.

SENSITIVITY

The minimum detectable dose of human HGH is typically less than 1 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.

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 g. Remove

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

     Avoid repeated freeze-thaw cycles.

     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.    Add    50μl   of Standard      or  Sample       per  well.   Then    add   50μl    of

     Biotin-antibody to   each   well.   Standards   need   test   in   duplicate.   Mix

     well and then incubate for 30 min at 37°C.

2.    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.

                                            6

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

3.    Add 50μl of HRP-conjugate to each well. Mix well and then incubate for

     30 min at 37°C.

4.    Wash the plate as before.

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

     Incubate for 15 minutes at 18-25°C. Keeping the plate away from drafts

     and other temperature fluctuations in the dark.

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

     appear uniform, gently tap the plate to ensure thorough mixing.

7.    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, control, and sample and

subtract the average zero standard optical density. 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

HGH 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.

                                             7

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

LIMITATIONS OF THE PROCEDURE

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

     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.

TECHNICAL HINTS

      When mixing or reconstituting protein solutions, always avoid foaming.

      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.

      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.

                                           8

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

      To   ensure   accurate   results,   proper   adhesion   of   plate   sealers   during

     incubation steps is necessary.

      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.

      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.
