Human CTDP1 (RNA polymerase II subunit A C-terminal domain phosphatase) ELISA KIT (HUFI05328)

CTDP1 is the catalytic subunit of RNA polymerase II carboxy-terminal domain phosphatase, also known as FCP1, which dephosphorylates Ser2 and Ser5 residues within the YSPTSPS heptad repeat of the RNA Pol II C-terminal tail. This Assay Genie kit enables quantitative measurement of CTDP1 protein in blood-derived samples, supporting research into transcription cycle regulation, mRNA 3'-end processing, and the role of CTDP1 in neurodegenerative conditions and congenital cataracts with hearing loss. The immunoassay is supplied as a complete kit with pre-coated microplate, capture antibody, detection antibody, standards, and substrate solution packed in individual vials. Researchers typically dispense 100 uL of sample per well, and the reagents should be stored refrigerated and protected from light. Intended for in vitro research use only, the kit supports gene expression studies, RNA Pol II phosphorylation investigations, and biomarker discovery workflows.
