背景知识
Different from polyclonal “human IgG1 isotype control antibodies” (人IgG1同型对照抗体)purified from human myeloma serum, the recombinant human IgG1 isotype control (hIgG1 kappa isotype control antibody) and mutants are produced in mammalian cells (HEK293 and CHO cells), thus are monoclonal and there is no potential contamination of any other antibody isotype(s). The recombinant human IgG1 isotype control (重组人IgG1同型对照抗体)has low or no specific binding to any human sample, and humanized or completely human variable regions in addition to the human IgG1 kappa constant regions. The human IgG1 kappa isotype control and mutants such as Fc-silenced can be used in ELISA, Western blot (WB), the cell-based assay or animal model as the antibody negative control.
A number of hIgG1 isotype control mutants(hIgG1同型对照突变体) are available. Most of the therapeutic antibody drugs carry the natural human IgG1 constant regions. There are some engineered mutants in the IgG1 Fc fragment. Changes to the IgG Fc sequence including glycosylation sites (such as N297A or N297G) have been used to modulate Fc functions. Even a single mutation may have both enhancement and abrogation effects on Fc binding though multiple mutation combinations are commonly used. We generated hIgG1 isotype control mutants(hIgG1同型对照突变体), the same mutations as those in the therapeutic antibodies and candidates because such human IgG1 isotype control mutants(人IgG1同型对照突变体) are needed when clients test their engineered antibody candidates. For example, P329G substitution combined with L234A L235A (hIgG1 LALAPG, Fc silenced) was shown to decrease effector functions by disrupting the Fc/Fcγ receptor interface. The silent Fc effctor functions human IgG1 isotype controls(人IgG1同型对照突变体) are useful for in vivo use.
The isotype controls are normally used to differentiate any non-specific background signal from the specific antibody signal, including the immunogenicity if used in animals. Most in vivo functional grade human IgG antibodies are used in mice for in vivo studies. Besides the antibody Complementarity-Determining Regions (CDRs), two human or humanized variable regions including the one in the human or humanized IgG isotype control do not necessarily induce the same immune response in mice because in some cases, even one amino acid difference can make difference. Mouse variable regions can be used to show the potential immunogenicity induced by the human variable regions in the human or humanized IgG antibodies to test. Thus, in some cases, it is better to use the mouse variable region in the human IgG isotype controls(人IgG 同型对照抗体). We also produce and sell recombinant human IgG isotype controls from the popuplar mouse hybridoma clones, MOPC21 and C1.18.4, as well as recombinant human IgG1 kappa isotype controls(人IgG1 kappa同型对照抗体) against KLH, TNP, DNP, GST, HEL, His-tag, Flag, c-myc, HA, GFP, and unknown specificity.
Please contact us to ask for a quote for the Fc silenced human IgG1 isotype control mutants, hIgG1 isotype control(人IgG1同型对照抗体) and silent Fc mutants with Avi-, His-, and Flag-tags, and biotinylated hIgG1 isotype control and Fc silent mutants. A variety of conjugates (such as a fluorophore) with the human IgG1 isotype control(人IgG1同型对照抗体) and Fc effector-silent mutants are available.
