Recombinant Alternatives

Animal-Free Recombinant Proteins for Research and Manufacturing Eliminate Pathogen Concerns

BSE and other animal-born pathogens are no longer an issue with Sigma's high purity recombinant alternatives. Recombinant proteins offer the reduced potential for contaminants, elimination of infectious agents, and defined composition.
