Anti-CPSF100 antibodies enable researchers to detect and measure the CPSF100 antigen in biological samples. This target is a reported synonym of the CPSF2 gene, which encodes cleavage and polyadenylation specific factor 2. This protein is a known component of the cleavage and polyadenylation specificity factor (CPSF) complex that play a key role in pre-mRNA 3'-end formation, recognizing the AAUAAA signal sequence and interacting with poly(A) polymerase and other factors to bring about cleavage and poly(A) addition. The human version of CPSF100 has a canonical amino acid length of 782 residues and a protein mass of 88.5 kilodaltons. 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 cleavage and polyadenylation specificity factor subunit 2. Indicated applications for CPSF100 antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
