Assay Principle

This kit is an Enzyme-Linked Immunosorbent Assay (ELISA). The plate has been pre-coated with Goat COR antibody. COR present in the sample is added and binds to antibodies coated on the wells. And then biotinylated Goat COR Antibody is added and binds to COR in the sample. Then Streptavidin-HRP is added and binds to the Biotinylated COR 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 Goat COR. The reaction is terminated by addition of acidic stop solution and absorbance is measured at 450 nm.

Intended Use

This sandwich kit is for the accurate quantitative detection of Goat Cortisol (also known as COR) in serum, plasma, cell culture supernates, cell lysates, tissue homogenates.

Reagent Provided

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.

Reagent Preparation

All reagents should be brought to room temperature before use.

Standard Reconstitute the 120μl of the standard (320ng/ml) with 120μl of standard diluent to generate a 160ng/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 (160ng/ml) 1:2 with standard diluent to produce 80ng/ml, 40ng/ml, 20ng/ml and 10ng/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:

Wash Buffer Dilute 20ml of Wash Buffer Concentrate 25x into deionized or distilled water to yield 500 ml of 1x Wash Buffer. If crystals have formed in the concentrate, mix gently until the crystals have completely dissolved.

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.

Advantages of our Sandwich kit

Without Diluting Sample

• Save assay time
• Wide detection range
• Reducing non-specific interactions between the sample matrix proteins

Streptavidin-biotin system

• Significant non-specific binding can be prevented by strepvidin
• Reducing interference from residual biotin in sample
• A non-covalent interaction with high affinity

Washing Step

• Only 5 times for one step
