Sample X-tra

The Sample X-tra™,   is used for dilution of samples matrices & assay standards for generating the standard curve in immunoassays such as ELISA, EIA, RIA, Protein Arrays, Western Blotting and Immuno-PCR.

In an ELISA, the buffer minimizes nonspecific interactions between the matrix proteins and the surface of the plate. This results in an improved Signal to Noice Ratio.
