Anti-U1-70K Antibody


Anti-U1-70K Antibody

Product type:  Primary Antibody
Clonality:         Polyclonal
Source:            Rabbit
Immunogen:  Recombinant human U1-70K (residues 1-215) expressed in E. coli.
Other name:  SNRNP70

Description:  U1-70K is a component of U1 snRNP involved in pre-mRNA splicing which binds to the loop 1 region of U1 snRNA. U1 snRNP is involved in the pre-spliceosome formation. U1-70K has RNA binding domain in its N-terminus and RS (arginine-serine)-like domain in the C-terminus. U1-70K is 436-residue long protein. Although the approximate MW of this protein ~50 KDa, it aberrantly migrates as a 70 KDa protein in SDS-PAGE.
Purification: Purified by affinity chromatography using a U170K affinity matrix.
Specificity: This antibody detects U1-70K protein in eukaryotic cell extract and recombinant proteins expressed in prokaryotic cells.
Recommended Dilutions:
Western Blotting   1:2,000
ELISA                      1:1,000
