*This product is for research use only, not for use in diagnosis
procedures. It’s highly recommend to read this instruction entirely
before use.
Assay Principle
This ELISA Assay Kit is an Enzyme-Linked Immunosorbent Assay (ELISA). The plate has been
pre-coated with Porcine PDGF antibody. PDGF present in the sample
is added and binds to antibodies coated on the wells. And then
biotinylated Porcine PDGF Antibody is added and binds to PDGF in
the sample. Then Streptavidin-HRP is added and binds to the
Biotinylated PDGF antibody. After incubation unbound
Streptavidin-HRP is washed away during a washing step. Substrate
solution is then added and color develops in proportion to the
amount of Porcine PDGF. The reaction is terminated by addition of
acidic stop solution and absorbance is measured at 450 nm.
Specimen Collection
Serum Allow serum to clot for 10-20 minutes at room temperature.
Centrifuge at 2000-3000 RPM for 20 minutes.
Plasma Collect plasma using EDTA or heparin as an anticoagulant.
Centrifuge samples for 15 minutes at 2000-3000 RPM at 2 - 8°C
within 30 minutes of collection.
Urine Collect by sterile tube. Centrifuge at 2000-3000 RPM for
approximately 20 minutes. When collecting pleuroperitoneal fluid
and cerebrospinal fluid, please follow the procedures
above-mentioned.
Cell Culture Supernatant Collect by sterile tubes when examining secrete components.
Centrifuge at 2000-3000 RPM for approximately 20 minutes. Collect
the supernatants carefully. When examining the components within
the cell, use PBS (pH 7.2-7.4) to dilute cell suspension to the
cell concentration of approximately 1 million/ml. Damage cells
through repeated freeze-thaw cycles to let out the inside
components. Centrifuge at 2000-3000 RPM for approximately 20
minutes.
Tissue Rinse tissues in PBS (pH 7.4) to remove excess blood thoroughly
and weigh before homogenization. Mince tissues and homogenize them
in PBS (pH7.4) with a glass homogenizer on ice. Thaw at 2-8°C or
freeze at -20°C. Centrifuge at 2000-3000 RPM for approximately 20
minutes.
Note
*Sample can't be diluted with this kit. Owing to the the material we use to prepare the kit, the sample
matrix interference may falsely depress the specificity and
accuracy of the assay.
Reagent Preparation
All reagents should be brought to room temperature before use.
Standard Reconstitute the 120μl of the standard (16ng/ml) with 120μl of
standard diluent to generate a 8ng/ml standard stock solution.
Allow the standard to sit for 15 mins with gentle agitation prior
to making dilutions. Prepare duplicate standard points by serially
diluting the standard stock solution (8ng/ml) 1:2 with standard
diluent to produce 4ng/ml, 2ng/ml, 1ng/ml and 0.5ng/ml solutions.
Standard diluent serves as the zero standard(0 ng/ml). Any
remaining solution should be frozen at -20°C and used within one
month. Dilution of standard solutions suggested are as follows:
8ng/ml | Standard No.5 | 120μl Original Standard + 120μl Standard Diluent |
4ng/ml | Standard No.4 | 120μl Standard No.5 + 120μl Standard Diluent |
2ng/ml | Standard No.3 | 120μl Standard No.4 + 120μl Standard Diluent |
1ng/ml | Standard No.2 | 120μl Standard No.3 + 120μl Standard Diluent |
0.5ng/ml | Standard No.1 | 120μl Standard No.2 + 120μl Standard Diluent |
Standard Concentration | Standard No.5 | Standard No.4 | Standard No.3 | Standard No.2 | Standard No.1 |
16ng/ml | 8ng/ml | 4ng/ml | 2ng/ml | 1ng/ml | 0.5ng/ml |
Wash Buffer Dilute 20ml of Wash Buffer Concentrate 30x into deionized or
distilled water to yield 600 ml of 1x Wash Buffer. If crystals have
formed in the concentrate, mix gently until the crystals have
completely dissolved.
Summary
1. Prepare all reagents, samples and standards.
2. Add sample and ELISA reagent into each well. Incubate for 1 hour
at 37°C.
3. Wash the plate 5 times.
4. Add substrate solution A and B. Incubate for 10 minutes at 37°C.
5. Add stop solution and color develops.
6. Read the OD value within 10 minutes.

ELISA Kit Categories
Sandwich Kit
Sandwich kits are fully validated and ready-to-use, containing 96-
well strip plates pre-coated with capture antibody to detect sample
antigen.
Competitive Kit
In a competitive ELISA assay, sample antigen and labeled antigen
compete for capture antibody binding. The more target protein there
is in the sample, the less labeled antigen will be captured and the
weaker the signal.
Qualitative Kit
Qualitative results provide a simple positive or negative result
for a sample. In quantitative ELISA, the optical density (OD) of
the sample is compared to a standard curve, which is typically a
serial dilution of a known-concentration solution of the target
molecule. It is suitable for detecting small antigens.
