SDS-PAGE analysis of recombinant Human IgA1 kappa

Recombinant human IgA1 kappa was analyzed under non-reducing, denaturing conditions (Lane 2) and reducing, denaturing conditions (Lane 3). Bands are visualized using Coomassie staining and the heavy (HC) and light chains (LC) are indicated, respectively. The molecular weights (kDa) of the marker proteins (Lane 1) are indicated on the left hand side of the image

Size exclusion chromatography of recombinant Human IgA1 kappa

UV280 chromatogram of a size exclusion chromatography run of recombinant human IgA1 kappa. The larger peak corresponds to monomeric, fully assembled AbD18705_hIgA1. The smaller shoulder most likely contains dimers and aggregates

    • Recombinant Human IgA1 kappa, clone AbD18705_hIgA1 is a recombinant human IgA1 antibody with a kappa light chain.

      Clone AbD18705_hIgA1 is specific for green fluorescent protein (GFP) and has no known reactivity with mammalian proteins or other antigens. This product is recommended for use as a standard in assays designed to measure IgA1 levels, or as a control antibody when using other human antibodies of the same isotype and subclass.

      Clone AbD18705_hIgA1 forms part of a range of human recombinant immunoglobins containing the kappa light chain. A similar range of reagents containing the lambda light chain is also available from Bio-Rad.
