Contract Research Proof of Concept: Simpson Biotech can transfer the SBP expression and purification system technology to the customer. The expression strain and detailed genetic information will be provided to the customer. The fermentation parameters and method including the culture media and fermentation condition as well as the downstream processing will be provided. Simpson Biotech can issue a non-exclusive, non-transferable license of the SBP-tag for the expression and purification of the target protein only. For E. Coli, Yeast, insect and mammalian cells a technical transfer fee will be assessed for each target protein product.
