| Formulation |
CSN2 protein solution (0.25mg/ml) containing 20mM Tris-HCl buffer (pH8.0), 10% glycerol, 0.5M NaCl, 0.25M imidazole, 1mM DTT and 0.1mM PMSF. |
| Purity |
Greater than 95.0% as determined by SDS-PAGE. |
| Description |
CSN2 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 236 amino acids (16-226 a.a.) and having a molecular mass of 26.6kDa.CSN2 is fused to a 25 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques. |
| Protein Background |
Beta-casein precursor (CSN2) is a member of the beta-casein family. CSN2 has an imperative role in determination of the surface properties of the casein micelles. CSN2 is specific to mammary glands and is secreted in milk. |
| Expression host |
Escherichia Coli. |
| Synonyms |
Beta-casein, CSN2, CASB. |
| Reagent Appearance |
Sterile Filtered clear solution. |
| 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).Avoid multiple freeze-thaw cycles. |
