Recombinant Protein A (C-6His)

• Background:

  The Protein A molecule contains four high-affinity (Ka =108/mole) binding sites capable of interacting with the Fc region from IgG of several species including human and rabbit. Optimal binding occurs a pH 8.2, although binding is also good at neutral or physiological conditions (pH 7.0-7.6).

• Molecular Weight:

  Approximately 34.7 kDa with 6×His-tag on C-terminus, a single non-glycosylated polypeptide chain containing 36 amino acids.

• CAS Number:

  9000-83-3
