Anti-RQCD1 antibodies enable researchers to detect and measure the RQCD1 antigen in biological samples. This target is a reported synonym of the CNOT9 gene, which encodes CCR4-NOT transcription complex subunit 9. This protein is known to function in cytokine-mediated signaling pathways and sex differentiation, among other biological roles. The human version of RQCD1 has a canonical amino acid length of 299 residues and a protein mass of 33.6 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include CAF40, CT129, and RCD-1. Indicated applications for RQCD1 antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
