Product Overview
This rabbit polyclonal antibody recognizes U1 small nuclear ribonucleoprotein C (gene SNRPC) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 17.4 kDa, and the supplier reports an observed band at about 17 kDa.
U1-C (SNRPC) is a U1 snRNP protein that stabilizes base pairing between U1 snRNA and the 5′ splice site of pre-mRNA. It is involved in the earliest step of splice site recognition for both constitutive and alternative splicing.

Immunogen
Recombinant human U1-C/SNRPC fragment (Met1–Arg159), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places U1 small nuclear ribonucleoprotein C in the nucleus. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
