Product Overview
Recombinant humanU-snRNP B/B acute;Full-length cDNA fused to a hexa-histidine purification tag. Expressedby recombinant baculovirus (Autographa californica multiple nuclearpolyhedrosis virus; AcMNPV) infection of Spodoptera frugiperda Sf9 insectcells.
(purity > 80%) SDS-PAGE; Western blot with i: SLE sera (Systemic LupusErythematosus); ii: monoclonal antihexa- His-tag antibody.
0.2–0.4μg/ml (depending on the type of ELISA plate and coating buffer). Suitable forbiotinylation and iodination.
Neutral to slightlyalkaline pH; due to purification workup under denaturing conditions presenceof up to 0.02 % SDS (or similar detergents) may be required for maintainingsolubility.
2-8°C short term, -20°C long term
Appears to function in the U7 snRNP complex that is involved in histone 3-end processing. Associated with snRNP U1, U2, U4/U6 and U5. May have a functional role in the pre-mRNA splicing or in snRNP structure. Binds to the downstream cleavage product (DCP) of histone pre-mRNA in a U7 snRNP dependent manner.
Antigen Description
Small nuclearribonucleoprotein-associated proteins B and B" is a protein that in humans isencoded by the SNRPB gene. The protein encoded by this gene is one of severalnuclear proteins that are found in common among U1, U2, U4/U6, and U5 smallribonucleoprotein particles (snRNPs). These snRNPs are involved in pre-mRNAsplicing, and the encoded protein may also play a role in pre-mRNA splicingor snRNP structure. Autoantibodies from patients with systemic lupuserythematosus frequently recognize epitopes on the encoded protein. Twotranscript variants encoding different isoforms (B and B") have been foundfor this gene.
