Anti-ROR3 antibodies enable researchers to detect and measure the ROR3 antigen in biological samples. This target is a reported synonym of the RORA gene, which encodes RAR related orphan receptor A. This protein is known to function in angiogenesis and the cellular response to hypoxia, among other biological roles. The human version of ROR3 has a canonical amino acid length of 523 residues and a protein mass of 59 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types. Other names for this target antigen include IDDECA, NR1F1, and ROR1. Western Blot is a widely used application for the ROR3 antibodies listed below. In addition, ELISA is also a common application.
