Sample X-tra

Sample X-tra is a sample dilution buffer for use in immunoassays such as ELISA, EIA, RIA, Protein Arrays, Western Blotting and Immuno-PCR. The buffer is used for dilution of biological matrices (like serum and plasma) as well as assay standards for generating the standard curve. In an ELISA, the buffer minimizes nonspecific interactions between the matrix proteins and the surface of the plate resulting in an improved signal-to-noise ratio. The buffer is completely free of any animal components.
