Eliminating the risk of contaminants and pathogens inherent to mammalian and other non-plant protein expression systems can offer developers tremendous value by reducing variables. Leveraging the power of plants via our FastPharming® system, we produce recombinant proteins using an entirely animal-free process.

Available Animal-Free Recombinant Proteins

The current catalog includes growth factors, cytokines, and lectins, given their critical roles in research and development efforts for various disease states including cancer and autoimmune disorders.

Our high-quality proteins can be used for a variety of applications, including SDS-PAGE, ELISA, cell culture supplementation, and western blot.

How Important is Glycosylation to Your Work?

The glycosylation profile of your protein may dictate your choice of expression system. Bacteria do not glycosylate; yeasts hyperglycosylate. CHO cell lines do not precisely mimic human glycosylation patterns.

iBio’s FastPharming plant-based protein expression system can deliver precise control of glycosylation and products with inherently greater N-linked glycosylation homogeneity versus alternative platforms.
