The DetectX® Ferric Reducing Antioxidant Power (FRAP™) Detection Kit is designed to quantitatively measure antioxidant status in a variety of samples. The assay measures the antioxidant ability from all species. A Ferrous Chloride standard is provided to generate a standard curve for the assay and all samples should be read off of the standard curve.

In the laboratory, ELISA is used to quantitatively measure or qualitatively detect any number of different target antigens. ELISAs are able to detect and quantify a wide variety of antigenic targets including peptides, proteins, antibodies, hormones, and small molecules.

When choosing an ELISA kit, most researchers demand an assay that is sensitive, specific, and highly-validated.

A sensitive assay is able to detect antigen at a very low titer in sample matrix (sometimes as low as pg/mL). A specific assay measures the target antigen only, and does not cross react with other common components inside normal sample matrices. A validated assay is accompanied by a sufficient quantity of data to confirm that both the sensitivity and specificity of the assay are consistent with the advertised specifications.
