Anti-CPSF3L antibodies are used in antigen-specific immunodetection in biological samples. The target CPSF3L is a known alias name of the protein integrator complex subunit 11, encoded by the INTS11 gene in humans. This 600-amino acid residue protein is reported to be a catalytic component of the Integrator (INT) complex, a complex involved in the small nuclear RNAs (snRNA) U1 and U2 transcription and in their 3'-box-dependent processing. It is localized to the nucleus and cytoplasm of the cell. It is reported to be widely expressed in many tissue types. The term CPSF73L is another synonym for CPSF3L. Indicated applications for CPSF3L antibodies listed below include ELISA, Western Blot, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry.
