Human IgG2/4 | AbD18705io
Recombinant Human IgG2/4 Kappa, clone AbD18705io (HCA337) was analysed under reducing, denaturing conditions (Lane 2) and non-reducing, denaturing conditions (Lane 3). Bands were visualized using Coomassie staining and the fully assembled antibody ((LC-HC)2), the heavy (HC) and light chains (LC) are indicated. The molecular weight (kDa) of the marker proteins (Lane 1) are displayed on the left hand side of the image.
UV280 chromatogram of a size exclusion chromatography run of recombinant human IgG2/4 kappa, clone AbD18705io (HCA337). The larger peak corresponds to monomeric, fully assembled AbD18705io. The smaller peaks most likely contain dimers and oligomers.
Recombinant Human IgG2/4 kappa, clone AbD18705io, contains a kappa light chain and a hybrid heavy chain constant region combining sequences from IgG2 and IgG4.
This product is a recombinant fully human 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 studies using IgG2/4 CH hybrid antibodies.
The heavy chain constant region of Recombinant Human IgG2/4 kappa consists of a fusion construct:
CH1, Hinge and N-terminal of CH2 identical to human IgG2 constant region (IMGT allele IGHG2*01)
C-terminal of CH2 and CH3 identical to human IgG4 constant region (IMGT allele IGHG4*04)
IgG2 and IgG4 are the least effector potent immunoglobulin subclasses, and have been combined in the design of antibodies that block their target without the induction of effector functions. An example is the therapeutic monoclonal antibody drug eculizumab (Soliris), which is used clinically to block complement factor C5, and is approved to treat the rare diseases paroxysmal nocturnal hemoglobinuria (PNH) and atypical hemolytic uremic syndrome (aHUS).
