Recombinant human Neuregulin-1 beta 1 (NRG1-β1) is a 65-amino-acid EGF-family growth factor supplied lyophilized for research use. It is expressed in E. coli, tag-free, and purified to greater than 95% for in vitro studies of cell signaling, neuronal development, and tumor biology. Store lyophilized at -20°C and follow supplier guidance for reconstitution and aliquoting.
- High purity (>95%) confirmed by reducing SDS-PAGE.
- 65 amino acids corresponding to S177-E241 of the mature protein.
- Tag-free recombinant protein suitable for functional assays.
- Lyophilized formulation with stabilizers for enhanced shelf life.
- Expressed in Escherichia coli for recombinant production.
- Predicted molecular mass ~7.5 kDa; ~8 kDa observed by SDS-PAGE.
- Available in small pack sizes including a 10 μg vial for pilot studies.
- Recommended storage: store lyophilized at -20°C; aliquot and keep at -80°C for long term after reconstitution.
