Recombinant human REG-1 beta (REG1B) protein expressed in HEK293 cells with a C-terminal His tag. Supplied lyophilized (5 μg) for biochemical assays, antibody work, and cellular studies where mammalian post-translational modifications are important. The product is ~19-20 kDa, >95% pure by reducing SDS-PAGE, and formulated in PBS (pH 7.4). Recommended storage is -20°C for long term; aliquot and freeze for extended stability.
- Mammalian expression preserves native glycosylation and folding.
- C-terminal His tag facilitates purification and detection.
- Lyophilized format enables long-term storage and easy transport.
- >95.0% purity by reducing SDS-PAGE ensures sample consistency.
- Supplied amount appropriate for small-scale assays (5 μg).
- Stable at -20°C for up to 2 years; aliquot to avoid freeze-thaw.
