Introduction
Chromosome 19 Open Reading Frame 80 (C19ORF80), a member of the ANGPTL protein family, is a crucial regulator of lipid metabolism. It may influence serum triglyceride levels by facilitating ANGPTL3 cleavage. This hormone plays a role in improving glucose tolerance by specifically promoting pancreatic beta cell proliferation and expansion. Primarily expressed in the liver, C19ORF80 is also found in adipose tissues. Its expression is responsive to food intake and stimulated by insulin.
Description
Recombinant C19ORF80 Mouse, produced in E. coli, is a non-glycosylated polypeptide chain consisting of amino acids 16-198 (including a 10 a.a. N-terminal His tag). This single chain protein has a calculated molecular mass of 21.8 kDa.
Physical Appearance
White powder, lyophilized after filtration.
Formulation
The protein was filtered (0.4 µm) and subsequently lyophilized from a 0.5 mg/ml solution in 30 mM acetate buffer with a pH of 4.
Solubility
To prepare a working solution, reconstitute the lyophilized pellet in 0.1 M Acetate buffer (pH 4) to an approximate concentration of 0.5 mg/ml. For use at a higher pH, dilute the solution with the relevant buffer to a concentration of 10 µg/ml. Note that the solubility of this antigen is limited at higher concentrations. This product is not sterile; filter through an appropriate sterile filter before use in cell culture.
Stability
Store the lyophilized protein at -20°C. Once reconstituted, aliquot the product to minimize freeze-thaw cycles. Reconstituted protein can be stored at 4°C for a limited period (up to two weeks) without significant degradation.
Purity
The purity is determined to be greater than 95% by SDS-PAGE analysis.
Synonyms
Betatrophin, Angiopoietin-like protein 8, Lipasin, Refeeding-induced fat and liver protein, Gm6484, Angptl8, Rifl, EG624219.
