Claudin 3 Colorimetric Cell-Based ELISA Kit is produced by Assay Biotech Company. It's also identified by the synonym '' Clostridium perfringens enterotoxin receptor 2 '' that is able to recognize, detecte and quantificate the endogenous levels of both recombinant and naturally produced Claudin 3 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 CD71/TfRprotein and its expression profile in cells. This kit can be used in order to measur with a hight precision the relative amounts of CD71/TfRinsid the cultured cells as well as detection of the effects that various inhibitors or treatments (ie. siRNA or chemicals), or activators have on CD71/TfR. It's has a colorimetric 450 nm as a detection method, within the range of > 5000 Cells.
