Anti-SNRPD2 Antibody

SNRPD2 (Small Nuclear Ribonucleoprotein D2) is a core component of the spliceosomal U snRNP particles, where it contributes to the assembly of U1, U2, U4/U6, and U5 small nuclear ribonucleoproteins that drive pre-mRNA splicing. This unconjugated rabbit polyclonal IgG antibody, supplied by Antibodies.com as a 200 µl aliquot, recognizes the human SNRPD2 protein and supports western blot, immunohistochemistry, and flow cytometry workflows that interrogate splicing factor expression, snRNP biogenesis, and Cajal body organization in human cells and tissues.

The polyclonal format yields recognition of multiple epitopes on SNRPD2, which is useful when probing low-abundance spliceosomal components or analyzing samples where the target may be partially fragmented during extraction. Investigators working on spinal muscular atrophy and SMN complex assembly, as well as those mapping changes in spliceosome composition during differentiation, cellular stress, or oncogenic transformation, can apply this reagent to detect endogenous SNRPD2 in lysates, fixed sections, and permeabilized cell suspensions. The unconjugated format also leaves the antibody available for downstream custom labeling with fluorophores, biotin, or enzymes according to individual assay requirements.
