Recombinant Proteins

Recombinant protein is a manipulated form of protein encoded by recombinant DNA, which has been cloned in a foreign expression system to supports the expression of the exogenous gene. This recombinant DNA construct can be used to manufacture large quantities of useful protein products. The recombinant DNA, usually the cDNA sequence of the target protein, is designed to be under the control of a well-characterized promoter to express the target protein within the chosen host cell to achieve high-level protein expression.

Our Advantages

Wide Coverage

•  100,000+ recombinant proteins covering most genes;

•  Multiple species (human, mouse, rat, rabbit, chicken, zebrafish, dog, monkey, pig…);

•  Multiple sources (CHO, HEK293, NS0, Sf 9 Insect cells, Sf21, E. coli, Yeast, Wheat Germ…);

•  Various tags (His, GST, Flag, T7, HA, MYC, Fc, Strep…) on N-terminus or C-terminus;

•  Different fragments/full-length protein/proteins with various mutations.

High Quality

•  Close to natural status;

•  Validated bio-activity using functional ELISA and/or other activity assays;

•  Lower endotoxin level: less than 0.1 EU per μg protein by LAL assay;

•  High purity: most of the products are over 90% pure by SDS-PAGE;
