Recombinant human Stem Cell Factor (SCF) produced in HEK293 cells and supplied as a C-terminal 6xHis-tagged, glycosylated protein. Supplied lyophilized in phosphate buffer with NaCl, the material is >95% pure by SDS-PAGE, low in endotoxin, and has demonstrated biological activity in TF-1 cell proliferation assays. Store lyophilized at -20°C; aliquot and freeze after reconstitution for long-term storage.
- Expression in HEK293 cells for human-like glycosylation.
- C-terminal 6xHis tag for purification and detection.
- Glycosylated protein with apparent mass ~30-50 kDa on SDS-PAGE.
- Purity greater than 95% by reducing SDS-PAGE.
- Low endotoxin level (<1 EU/μg) suitable for cell-based assays.
- Bioactivity validated by TF-1 cell proliferation (ED50 ≈ 1.1 ng/mL).
- Lyophilized formulation for stability and convenient handling.
- Recommended storage: lyophilized at -20°C; aliquot and freeze after reconstitution.
