Bio-Rad, HCA319, Human IgG1 | AbD18705il

Recombinant Human IgG1 kappa allotype G1m17,1, clone AbD18705il is a recombinant human antibody with a kappa light chain, and heavy chain belonging to the G1m17,1 allotype, also designated G1m(z,a). 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 control reagent for assays where this immunoglobulin is measured, or when using other human IgG1 antibodies of the same isotype or allotype. It is recommended that this reagent is used at the same concentration as the test reagent. The main allelic forms of IgG1 are G1m(z,a), G1m(f), and G1m(f,a). The G1m(z,a) (or G1m17,1) allele is found in Caucasoid, Negroid and Mongoloid populations, whereas the G1m3 allele is only found in Caucasoid; 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 G1m3 , and the corresponding allotypes for IgG1 lambda.

Storage Information
This product is shipped at ambient temperature. It is recommended to aliquot and store at -20°C on receipt. When thawed, aliquot the sample as needed. Keep aliquots at 2-8°C for short term use (up to 4 weeks) and store the remaining aliquots at -20°C.
Avoid repeated freezing and thawing as this may denature the antibody. Storage in frost-free freezers is not recommended.
