Anti-CRS1 antibodies enable researchers to detect and measure the CRS1 antigen in biological samples. This target is a reported synonym of the TWIST1 gene, which encodes twist family bHLH transcription factor 1. This protein is known to function in the cellular response to hypoxia, among other biological roles. The human version of CRS1 has a canonical amino acid length of 202 residues and a protein mass of 21 kilodaltons. It is reported to be localized in the nucleus of cells. Other names for this target antigen include ACS3, BPES2, and BPES3. Western Blot is a widely used application for the CRS1 antibodies listed below. In addition, ELISA is also a common application.
