Enzyme-linked immunosorbent assay (ELISA) is an analytic biochemical assay that utilizes enzyme-linked antibodies on a microwell platform to quantitate specific proteins within biological samples. Visual detection is then achieved by adding the enzyme’s substrate, which causes a color-changing reaction to occur. There are three different types of ELISA that are most commonly used: indirect ELISA, sandwich ELISA and competitive ELISA. These assays are extremely useful for high-throughput diagnostic screenings drug testing.

Z-scores are described in units of standard deviations (SD's) above the mean value of all signals generated on that array. If targets on HuProt(TM) are arranged in descending order of the Z-score, the S-score is the difference (also in units of SD's) between the Z-score. S-score therefore represents the relative target specificity of a MAb to its intended target. A MAb is considered to specific to its intended target, if the MAb has an S-score of at least 2.5.](http://images.novusbio.com/fullsize/Spectrin-alpha-1-Antibody-SPTA1-1832-Protein-Array-NBP2-79772-img0003.jpg)
