Anti-PRP31 antibodies enable researchers to detect and measure the PRP31 antigen in biological samples. This target is a reported synonym of the PRPF31 gene, which encodes pre-mRNA processing factor 31. This protein is known to function in RNA splicing, among other biological roles. The human version of PRP31 has a canonical amino acid length of 499 residues and a protein mass of 55.5 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 NY-BR-99 and RP11. Western Blot is a widely used application for the PRP31 antibodies listed below. In addition, ELISA is also a common application.
