ARHGEF2 Colorimetric Cell-Based ELISA Kit is produced by Assay Biotech Company. It's also identified by the synonym '' Guanine nucleotide exchange factor GEF-H1 '' that is able to recognize, detecte and quantificate the endogenous levels of both recombinant and naturally produced ARHGEF2 proteins, within any experimental sample including cell lysates, serum and plasma. and that is an appropriate, lysatefree, high throughput and high sensitivity assay kit that can check AIREprotein and its expression profile in cells. This kit can be used in order to measur with a hight precision the relative amounts of AIREinsid the cultured cells as well as detection of the effects that various inhibitors or treatments (ie. siRNA or chemicals), or activators have on AIRE. It's has a colorimetric 450 nm as a detection method, within the range of > 5000 Cells.
