Our Molecular Immunology group produces high quality recombinant proteins that are:
  • >95% pure
  • Endotoxin tested (LAL assay) to assure it is safe for use in biological systems.
  • Available in a carrier-free format.
  • Tested in bioassays side-by-side with a previous lot and with a control from a competitor.
  • Stability tested to determine the optimal storage conditions.
Animal-Free Recombinant Proteins
BioLegend is proud to release our line of animal-free recombinant proteins, which greatly minimize the variables and potential contamination of mammalian pathogens during the production process. All of these proteins are produced in animal-free media, and the purification equipment itself is also animal component free. The animal-free versions of these proteins function in a similar manner to their animal-derived counterparts. Treat your cells to animal-free recombinant proteins and see how they prosper!
