Rabbit IgG Fc protein

Background

In vivo grade recombinant natural and engineered rabbit IgG Fc proteins (rIgG Fc), and recombinant rabbit IgG isotype control antibody and mutants are available. Biotinylated rIgG Fc, and rIgG Fc with Avi-, His-, and Flag-tags are also available. Please contact us to ask for a quote for the engineered rabbit IgG Fc proteins, biotinylated rIgG Fc, and rIgG Fc with Avi-, His-, and Flag-tags. The recombinant rabbit IgG Fc protein and mutants can be used as the isotype control of the rIgG antibodies and the rIgG Fc fusion proteins in various in vitro and in vivo experiments.

The in vivo grade recombinant rabbit IgG Fc protein (rIgG Fc, Cys 105 - Lys 323 of the constant region of the IgG heavy chain, Accession # P01870-1) was produced in mammalian cells and purified by protein A. The rIgG Fc protein includes the CH2 (114-213) and CH3 (222-323) domains of the heavy chain constant region as well as the hinge region (105-113) before the CH2 domain. 
Molecular weight: Predicted 24.8 kDa. Due to glycosylation, the recombinant rabbit IgG Fc protein migrates to 28-32 kDa based on the Bis-Tris PAGE result.
Purity: >95% by SDS-PAGE under reducing conditions
Endotoxin Level: Less than 1 EU/mg of protein as determined by LAL method.
Formulation: 0.2 μM filtered solution of 1x PBS.
