Go to datasheet (ab31891)

Question

Please advise the isotype control for ab31891 to be used in FlowCyt.

Answer

The ab31891 Anti-ErbB2 Affibody® is not an antibody, but an 'Affibody'. The backbone of Affibody® molecules are derived from a 58 amino acid IgG-binding domain of Staphylococcal Protein A. There is further information on 'Affibodies' on the datasheet for this product. An IgG isotype control works only with antibodies and is not applicable for Affibody® Molecules.
