These CRS1 ELISA kits are immunodetection tools for measuring the levels of CRS1 in biological samples. CRS1 is an alias of the human TWIST1 gene, which encodes the protein, twist family bHLH transcription factor 1. Notably, CRS1 is known to play a role in the cellular response to hypoxia, among other functions. The TWIST1 protein is described to be 202 amino acid residues in length and 21 kilodaltons in mass. It is localized to the nucleus of the cell. Other names for this target antigen include ACS3, BPES2, and BPES3.
