Recombinant Human Small Nuclear Ribonucleoprotein Polypeptide B

Source : Escherichia Coli. SNRPB2 Human Recombinant fused with a 20 amino acid His tag at N-terminus produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 245 amino acids (1-225a.a.) and having a molecular mass of 27.6kDa. The SNRPB2 is purified by proprietary chromatographic techniques. SNRPB2 is a member of the RRM U1 A/B family. SNRPB2 links with stem loop IV of U2 small nuclear ribonucleoprotein (U2 snRNP) in the presence of snRNP-A. SNRPB2 has a part in pre-mRNA splicing. Autoantibodies from patients with systemic lupus erythematosus often identify epitopes on the encoded protein. A pair of transcript variants encoding the same protein were identified for this gene.

Greater than 90.0% as determined by SDS-PAGE.

The SNRPB2 solution (0.25mg/mL) contains 20mM Tris-HCl buffer (pH 8.0), 40% glycerol and 0.1M NaCl.

SNRPB2 should be stored desiccated below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA) . Please prevent freeze-thaw cycles.
