Tryptophan Hydroxylase Cell Based ELISA Kit (A102799)

Tryptophan Hydroxylase Cell Based ELISA Kit

Cell-based (qualitative)

This Tryptophan Hydroxylase Cell Based ELISA Kit allows for the detection of Tryptophan Hydroxylase and the effects that certain stimulation conditions have on Tryptophan Hydroxylase expression in different cell lines. Qualitative determination of Tryptophan Hydroxylase concentration is achieved by an indirect ELISA format. In essence, the Tryptophan Hydroxylase is captured by Anti-Tryptophan Hydroxylase Antibodies which in turn are detected by HRP-conjugated secondary antibodies. Through this binding, the HRP enzyme (conjugated to the secondary antibody) can catalyze a colorimetric reaction upon substrate addition. Due to the qualitative nature of this Tryptophan Hydroxylase Cell Based ELISA Kit, multiple normalization methods are described: 1) Anti-GAPDH Antibody is included to serve as an internal positive control in normalizing the target absorbance values. 2) Following the colorimetric measurement of HRP activity via substrate addition, the Crystal Violet whole-cell staining method is used to determine cell density. After staining, the results can be analyzed by normalizing the absorbance values to cell amounts, by which the plating difference can be adjusted.
