Recombinant monoclonal antibody to IgG1 Fc. Manufactured using AbAb’s Recombinant Platform with variable regions (i.e. specificity) from the phage display antibody TP881.
Alternative Name(s) of Target: immunoglobulin G1 fragment crystallizable region; immunoglobulin G1 Fc region; immunoglobulin G1
Immunogen: This antibody was raised by immunising alpacas with 1.0 mg polyclonal mouse IgG. Subsequently, the generation of nanobody immune libraries and the selection of antigen-specific nanobodies by phage display from these libraries were performed.
Specificity: This antibody recognises Fc fragment of the IgG1.
Application Notes: TP881 nanobody can be used for the purification of antigens or antigen complexes previously bound to a primary antibody, as it successfully isolated mouse monoclonal IgG1 from hybridoma cell culture supernatant and then released it under physiological conditions using SUMOStar protease cleavage (Pleiner et al., 2018).
