Introduction
The KCNMB3 belongs to a family of 4 auxiliary beta subunits found in the mammalian genome, which associate with Slo1 alpha subunits and regulate BK channel function. In humans, the KCNMB3 gene is comprised of 4 N-terminal alternative exons which produce 4 functionally distinct beta3 subunits, beta3a-d. Three variants, beta3a-c, display kinetically distinct inactivation behaviors.
Description
KCNMB3 Human Recombinant produced in E.Coli is a single,
non-glycosylated polypeptide chain containing 149 amino acids (82-207 a.a) and
having a molecular mass of 16.8kDa.
KCNMB3 is fused to a 23 amino acid His-tag at N-terminus
& purified by proprietary chromatographic techniques.
Source
Escherichia Coli.
Physical Appearance
Sterile Filtered colorless solution.
Formulation
KCNMB3
protein solution (1mg/ml) containing 20mM Tris-HCl buffer (pH 8.0), 0.4M UREA
and 10% glycerol.
Stability
Store at 4°C if entire vial will be used within 2-4 weeks.
Store, frozen at -20°C for longer periods of time.
