Introduction
Adiponectin, a 30 kDa adipocyte complement-related protein comprising 247 amino acids, is exclusively expressed in differentiated adipocytes. APM-1 (Acrp30 Mouse), a member of the complement factor C1q family, consists of a signal sequence, a non-homologous sequence, a collagen domain, and a globular domain (gAcrp30). Adiponectin expression is reduced in various obese and insulin-resistant states in humans, monkeys, and mice. Injecting Acrp30 Mouse (247aa) or gAcrp30 lowers serum glucose and free fatty acid levels in mice.
Description
The recombinant globular domain of mouse Adiponectin/Acrp30, encompassing amino acid residues 111-247 with a molecular mass of 16 kDa, was overexpressed in E. coli and purified using standard chromatographic techniques.
Physical Appearance
Clear, colorless solution, sterile-filtered.
Formulation
Acrp30 Mouse solution (1 mg/ml) in 20 mM Tris-HCl (pH 7.5), 50 mM NaCl, 5 mM DTT, and 10% glycerol.
Stability
For short-term storage (2-4 weeks), store at 4°C. For long-term storage, freeze at -20°C. Adding a carrier protein (0.1% HSA or BSA) is recommended for extended storage. Avoid repeated freeze-thaw cycles.
Purity
Purity exceeds 95.0% as determined by SDS-PAGE.
Synonyms
Acrp30, AdipoQ, GBP-28, APM-1, ACDC.
