SNRNP70 Human

Small Nuclear Ribonucleoprotein 70kDa Human Recombinant

Recombinant Human U1-snRNP 68kDa cDNA codes for the 70kDa isoform of the human U1-snRNP 68 protein (lacking 66 internal amino acids outside the known epitope-containing areas) fused to a hexahistidine purification tag.
The Calculated molecular weight is 44.8 kDa (U1-snRNP 68 displays aberrant electrophoretic mobility leading to an apparent discrepancy between calculated molecular weight and the 55-56 kDa molecular weight determined for this internally shortened molecule by SDS gel electrophoresis).

Accession

P08621

Applications

Western-Blot with monoclonal anti-hexa-His-tag antibody & MCTD sera (Mixed Connective Tissue Disease).

Coating concentration

0.3-0.6 ug/ml (depending on the type of ELISA plate and coating buffer).
Suitable for biotinylation and iodination.

Formulation

U1-snRNP is supplied in 20mM HEPES buffer pH-7.5, 0.01mM EDTA and 0.02% SDS.

Immunological Function

1. Binds IgG-type human auto-antibodies.
2. Standard ELISA test (checker-board analysis of positive/negative sera panels including CDC international reference sera).

Physical Appearance

Sterile Filtered clear solution.

Purity

Greater than 90% as determined by SDS-PAGE.

Source

Escherichia Coli.
