Recombinant Proteins

We provide over 5000 recombinant proteins expressed by HEK293 and E.Coli for Western Blot and ELISA application. Our pET28a-IF2D1 expression vector features a powerful fusion tag, providing a superior alternative to GST, MBP, and similar tags. This vector's lower molecular weight minimizes interference with target protein expression.

In addition to the popular E. coli expression system, XpressBio offers a HEK293 cell-based eukaryotic expression system. This system allows for the production of proteins with closer resemblance to their natural form, potentially enhancing their activity.

Our recombinant proteins provide:

  • Over 95% protein purity 
  • Reproducible protein test 
  • Image-based validation
