Anti-CTDSP1 Antibody

CTDSP1 is a C-terminal domain phosphatase that dephosphorylates the RNA polymerase II C-terminal domain and contributes to transcriptional regulation, snRNP biogenesis, and cell cycle progression. This unconjugated polyclonal reagent from Antibodies.com is raised in rabbit and validated across western blot, immunohistochemistry, and ELISA workflows, giving laboratories a single reagent for protein detection in lysates, fixed sections, and plate-based assays.

The antibody cross-reacts with CTDSP1 orthologues in mouse and rat tissue, supporting comparative work between rodent models and human samples without swapping primaries. It is supplied as a 100 µl liquid aliquot of rabbit serum-derived IgG, enough for multiple immunoblot membranes and staining runs from a single vial. Researchers studying neuronal differentiation, prostate and breast tumor biology, or polymerase II CTD phosphorylation dynamics use anti-CTDSP1 reagents to profile phosphatase expression in nuclear extracts and paraffin-embedded sections. Pair the primary with HRP- or fluorophore-conjugated secondary antibodies for WB and IHC detection, or use it as the capture antibody in ELISA readouts where target-specific recognition matters.
