Background Information

U2 small nuclear ribonucleoprotein B''(SNRPB2) is part of the U2 RNP particle, which associated with the branch point of the lariat-shaped intron, in intermediate in the cascade of mRNA precursor splicing event. Only in presence of the U2A' protein, SNRPB2 binds stem loop IV of U2 snRNA.

Melissa (Verified Customer) (03-16-2020)

This antibody works incredibly robust in western blot analysis. However, we do observe a non-specific band in all of our blots which we have attributed to snRPA due to the size and sequence similarity of the immunogen.

• Applications: Western Blot,
• Primary Antibody Dilution: 1:1000
• Cell Tissue Type: HeLa Cell Nuclear Extract
