Recombinant Human IgG1 YTE Kappa allotype G1m3, clone AbD18705iu is a recombinant human antibody with a kappa light chain, and a heavy chain belonging to the G1m3 allotype, also designated G1m(f). It contains a M252Y, S254T, T256E (YTE) triple mutation at the interface between the CH2 and CH3 domains of its Fc region. The introduction of the YTE mutation in the Fc region of an antibody has been shown to increase its half life by a 4-5 fold due to an increase in the antibody affinity to the neonatal Fc receptor (FcRn). It is therefore a mutation of choice for the generation of biotherapeutic antibodies.

This product is a recombinant antibody with specificity for green fluorescent protein (GFP). It has no known reactivity with mammalian proteins or other antigens. It is therefore recommended as a relevant control for scientists working on the R&D of therapeutic antibodies with this engineered Fc region. It is recommended that this reagent is used at the same concentration as the test reagent.

The main allelic forms of IgG1 are G1m(f), G1m(f,a), and G1m(z,a). The G1m(f) (or G1m3) allele is only found in Caucasoid populations, whereas the G1m(f,a) allele is common in Mongoloids, but other variants, G1m(z,a,x) and G1m(z,a,v), have also been described; for further details on IgG1 allotypes see IgG subclasses and allotypes: from structure to effector functions, and IMGT Repertoire (IG and TR) Allotypes: Human (Homo sapiens) IGHC.

The following publication reviews the serologically defined human IgG allotypes and considers the potential for allotype differences to contribute to or potentiate immunogenicity; Human immunoglobulin allotypes, possible implications for immunogenicity

Our range of IgG1 controls also includes Recombinant Human IgG1 kappa allotype G1m17,1, and the corresponding allotypes for IgG1 lambda.
