Recombinant Human IL-7 Protein
IL-7

An innovative, high-quality cytokine enabling smarter cell and gene therapy
The IL-7 manufacturing process has been optimized to produce a highly bioactive protein with excellent lot-to-lot consistency for enhanced experimental reproducibility. BioLife Solutions IL-7 is a highly pure 17.5 kDa monomer that is AOF certified and CF.
Animal origin-free (AOF) and carrier protein-free (CF)
Manufactured under a certified ISO 9001:2015 Quality Management System
17.5 kDa
>98%, by SDS-PAGE quantitative densitometry
Expressed in E. coli
Lyophilized from acetonitrile, TFA
Resuspend in sterile-filtered water at >50 μg/mL, add carrier protein if desired, prepare single use aliquots and store frozen at -20°C (short-term) or -80°C (long-term).
