Recombinant protein selection table

Invitrogen™ Recombinant Proteins

Low-endotoxin and validated via bioassay and SDS-PAGE. They are provided in a carrier-free format ideal for cell culture or production of standards for ELISA or western blotting.

Gibco® Growth Factors

Gibco® growth factors have high biological activity so you can get more results with less protein, high purity to minimize interference from proteins or other contaminants, and proven compatibility when bioassayed with Gibco® media.

Sino Biological Recombinant Proteins

Sino Biological proteins offer great value with prices below competitive brands, quality with mammalian expressed proteins >90% pure, and choice of a variety of different sizes, species, and tags to meet your needs.
