Recombinant human regenerating islet-derived protein 1 beta (REG1B), expressed in HEK293 cells with a C-terminal His tag, supplied as a lyophilized powder. Intended for biochemical and cell-based research applications including studies of tissue regeneration, neuronal growth, and calcium carbonate precipitation; biological activity has been reported in a cell proliferation assay (ED50 ≈ 0.657 μg/mL).
- Human REG1B protein, full-length mature sequence (Q23-N166).
- HEK293 expression preserves mammalian post-translational modifications.
- C-terminal His tag facilitates purification and detection.
- Lyophilized formulation with low endotoxin (<1 EU/μg) for sensitive assays.
- High purity (>95.0% by reducing SDS-PAGE) suitable for biochemical work.
- Biological activity validated in a cell proliferation assay (ED50 ≈ 0.657 μg/mL).
