Introduction
Neuronal Regeneration Related Protein (NREP) is involved in neural function, specifically in promoting axonal regeneration. It also plays a role in cellular differentiation, including inducing fibroblast differentiation into myofibroblasts and enhancing retinoic-acid regulation of lipid-droplet biogenesis. NREP downregulates the expression of transforming growth factor beta 1 (TGFB1) and TGFB2, but not TGFB3. Additionally, it contributes to the regulation of alveolar generation.
Description
Recombinant human NREP, expressed in E. coli, is a single, non-glycosylated polypeptide chain consisting of 91 amino acids (residues 1-68) with a molecular weight of 10.3 kDa. It includes a 23 amino acid His-tag fused to the N-terminus and is purified using proprietary chromatographic techniques.
Physical Appearance
A sterile, filtered solution that is colorless.
Formulation
The NREP solution is provided at a concentration of 0.5 mg/ml in a buffer consisting of 20 mM Tris-HCl (pH 8.0), 10% glycerol, and 0.1 M NaCl.
Stability
For short-term storage (2-4 weeks), keep refrigerated at 4°C. For extended storage, freeze at -20°C. Adding a carrier protein (0.1% HSA or BSA) is recommended for long-term storage. Minimize repeated freeze-thaw cycles.
Purity
Purity is determined to be greater than 85.0% using SDS-PAGE analysis.
