Introduction
SSR is a glycosylated endoplasmic reticulum (ER) membrane receptor involved in protein translocations across the ER membrane. SSR is formed of 2 subunits, a 34-kD glycoprotein encoded by this gene and a 22-kD glycoprotein. SSR gene creates a number of mRNA species due to complex alternative polyadenylation. SSR is unique since it exploits arrays of polyA signal sequences which are mostly non-canonical.
Description
SSR1 Human Recombinant produced in E.Coli is a single,
non-glycosylated polypeptide chain topological domain containing 209 amino
acids (22-207 a.a) and having a molecular mass of 23.1kDa. SSR1 is fused to a 23 amino
acid His-tag at N-terminus & purified by proprietary chromatographic
techniques.
Source
Escherichia Coli.
Physical Appearance
Sterile Filtered clear solution.
Formulation
SSR1 protein solution (0.25mg/ml) containing 20mM
Tris-HCl buffer (pH8.0), 0.1M NaCl, 1mM DTT and 20% 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.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please avoid freeze thaw cycles.
