INTRODUCTION
Interleukin-10 (IL-10), also known as human cytokine synthesis inhibitory
factor (CSIF), is an anti-inflammatory cytokine. This cytokine is produced
primarily by monocytes and to a lesser extent by lymphocytes. This
cytokine has pleiotropic effects in immunoregulation and inflammation. It
down-regulates the expression of Th1 cytokines, MHC class II antigens,
and costimulatory molecules on macrophages. It also enhances B cell
survival, proliferation, and antibody production. This cytokine can block
NF-κB activity, and is involved in the regulation of the JAK-STAT signaling
pathway. Knockout studies in mice suggested the function of this cytokine
as an essential immunoregulator in the intestinal tract. A study in mice has
shown that interleukin-10 is also produced by mast cells, counteracting the
inflammatory effect that these cells have at the site of an allergic reaction.
PRINCIPLE OF THE ASSAY
The microtiter plate provided in this kit has been pre-coated with an
antibody specific to IL-10 Standards or samples are then added to the
appropriate microtiter plate wells with a biotin-conjugated polyclonal
antibody preparation specific for IL-10 and Avidin conjugated to
Horseradish Peroxidase (HRP) is added to each microplate well and
incubated. Then a TMB (3,3’5, 5’ tetramethyl-benzidine) substrate solution
is added to each well. Only those wells that contain IL-10, biotin-conjugated
antibody and enzyme-conjugated Avidin will exhibit a change in color. 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 IL-10 in the samples is
then determined by comparing the O.D. of the samples to the standard
curve.

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, provided it is stored as
prescribed above. Refer to the package label for the expiration date.
2. Opened test plate should be stored at 2-8°C in the aluminum foil bag
with desiccants to minimize exposure to damp air. The 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.
REAGENT PREPARATION
Bring all reagents to room temperature before use.
1. Wash Buffer If crystals have formed in the concentrate, warm up to
room temperature and mix gently until the crystals have completely
dissolved. Dilute 20 ml of Wash Buffer Concentrate into deionized or
distilled water to prepare 500 ml of Wash Buffer.
2. Standard Centrifuge the standard vial at 6000-10000rpm for 30s.
Reconstitute the Standard with 1.0 ml of Sample Diluent. This
reconstitution produces a stock solution of 200 pg/ml. Allow the
standard to sit for a minimum of 15 minutes with gentle agitation prior to
making serial dilutions. The undiluted standard serves as the high
standard (200 pg/ml). The Sample Diluent serves as the zero standard
(0 pg/ml). Prepare fresh for each assay. Use within 4 hours and discard
after use.

----------------------- Page 5-----------------------
3. Biotin-antibody Centrifuge the vial before opening. Dilute to the
working concentration using Biotin-antibody Diluent(1:100),
respectively.
4. HRP-avidin Centrifuge the vial before opening. Dilute to the working
concentration using HRP-avidin Diluent(1:100), respectively.
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.
An incubator which can provide stable incubation conditions up to
37°C±0.5°C.
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 immediately or aliquot and store samples at -20°C.
Centrifuge the sample again after thawing before the assay. 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 immediately or aliquot and store samples at -20°C.
Centrifuge the sample again after thawing before the assay. Avoid
repeated freeze-thaw cycles.
Note: Grossly hemolyzed samples are not suitable for use in this assay.

----------------------- Page 6-----------------------
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.
All the reagents should be added directly to the liquid level in the well. The
pipette should avoid contacting the inner wall of the well.
1. Add 100l of Standard, Blank, or Sample per well. Cover with the
adhesive strip. Incubate for 2 hours at 37°C.
2. Remove the liquid of each well, don’t wash.
3. Add 100l of Biotin-antibody working solution to each well. Incubate
for 1 hour at 37°C. Biotin-antibody working solution may appear
cloudy. Warm up to room temperature and mix gently until solution
appears uniform.
4. Aspirate each well and wash, repeating the process three times for a
total of three washes. Wash: Fill each well with Wash Buffer (200l) and
let it stand for 2 minutes, then remove the liquid by flicking the plate
over a sink. The remaining drops are removed by patting the plate on a
paper towel. Complete removal of liquid at each step is essential to
good performance.
5. Add 100l of HRP-avidin working solution to each well. Cover the
microtiter plate with a new adhesive strip. Incubate for 1 hour at 37°C.
6. Repeat the aspiration and wash three times as step 4.
7. Add 90l of TMB Substrate to each well. Incubate for 10-30 minutes at
37°C. Keeping the plate away from drafts and other temperature
fluctuations in the dark.
8. Add 50l of Stop Solution to each well when the first four wells
containing the highest concentration of standards develop obvious blue
color. If color change does not appear uniform, gently tap the plate to
ensure thorough mixing.
9. Determine the optical density of each well within 30 minutes, using a
microplate reader set to 450 nm.

----------------------- Page 7-----------------------
CALCULATION OF RESULTS
Using the professional soft "Curve Exert 1.3" to make a standard curve is
recommended, which can be downloaded from our web.
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
IL-10 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.
Do not mix or substitute reagents with those from other lots or sources.
It is important that the Standard 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 Standard 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 Immunoassay, the possibility of
interference cannot be excluded.
TECHNICAL HINTS
Centrifuge vials before opening to collect contents.
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.
To ensure accurate results, proper adhesion of plate sealers during
incubation steps is necessary.
Substrate Solution should remain colorless or light blue until added to
the plate. Keep Substrate Solution protected from light. Substrate
Solution should change from colorless or light blue 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.
