Chicken SAA ELISA Assay

Product Overview:

The chicken SAA ELISA assay kit is a highly sensitive two-site ELISA for measuring serum amyloid A in biological fluid of chickens.

Assay Principle:

In this assay the serum amyloid A (SAA) present in samples reacts with the anti-SAA antibodies which have been adsorbed to the surface of polystyrene microtitre wells. After the removal of unbound proteins by washing, anti-SAA antibodies conjugated with horseradish peroxidase (HRP) are added. These enzyme-labeled antibodies form complexes with the previously bound SAA. Following another washing step, the enzyme bound to the immunosorbent is assayed by the addition of a chromogenic substrate, 3,3’,5,5’-tetramethylbenzidine (TMB). The quantity of bound enzyme varies directly with the concentration of SAA in the sample tested; thus, the absorbance, at 450 nm, is a measure of the concentration of SAA in the test sample. The quantity of Serum Amyloid A in the test sample can be interpolated from the standard curve constructed from the standards, and corrected for sample dilution.

Sensitivity:

0.094 ng/ml

Dynamic Range:

0.375 ng/ml – 24 ng/ml

Incubation Time:

90 minutes

Sample Type:

Plasma, serum

Sample Size:

100 µl

Specimen Collection and Handling:

Blood should be collected by venipuncture. The serum should be separated from the cells after clot formation by centrifugation. For plasma samples, blood should be collected into a container with an anticoagulant and then centrifuged. Care should be taken to minimize hemolysis, excessive hemolysis can impact your results. Assay immediately or aliquot and store samples at -20C. Avoid repeated freeze-thaw cycles.
