Need to avoid BSA or albumin from an animal source?  Recombinant Albumin (rAlbumin), Molecular Biology Grade, is a non-bovine derived albumin that can serve as an alternative to Bovine Serum Albumin (BSA).  Like BSA, it has been shown to prevent adhesion of enzymes to reaction tubes and pipette surfaces.  It also stabilizes some proteins during incubation. Choose Recombinant Albumin, when there is a need to avoid BSA.

Equivalent stability performance between BSA and Recombinant Albumin. BSA and Recombinant Albumin are used to stabilize enzymes in a reaction. NcoI-HF (NEB #R3193) was formulated with either BSA, Molecular Biology Grade or Recombinant Albumin and then stored at -20°C for 2 years. Serial dilutions were then performed. The data shows equivalency between enzyme formulated with BSA, Molecular Biology Grade and Recombinant Albumin.

Recombinant Albumin (rAlbumin) that can serve as an alternative to BSA, which can prevent adhesion of enzymes to reaction tubes and pipette surfaces as well as stabilizes some proteins during incubation. Please inquire about custom formulations with Recombinant Albumin.
