In vivo Grade Recombinant MOPC

The MOPC-21 antibody (IgG1, kappa) has been used for a long time as an isotype-matched control antibody to estimate the degree of non-specific binding by an antigen-specific antibody. The variable regions of the MOPC-21 antibody share the sequences with the antibodies against all members of the dengue virus complex, and the Epstein-Barr virus gp350 protein. The recombinant MOPC-21 IgG1 kappa isotype control and mutants (natural and engineered mIgG1 isotype controls) are useful for in vitro and in vivo studies from ELISA, Western blot (WB), to cell-based assay to animal model study. Mouse IgG1 isotype control and mutants (natural and engineered mIgG1 isotype controls) are useful for in vitro and in vivo studies from ELISA, Western blot (WB), to cell-based assay to animal model study. The isotypes of mouse IgG antibody reagents used in scientific research and clinical diagnostics are mainly mouse IgG1 kappa. Mouse IgG1 antibodies and engineered mutants are also used in therapeutic drug discovery. Mouse IgG1 antibodies are more like human IgG4 antibodies than human IgG1 antibodies, which behave more like mouse IgG2a or IgG2c antibodies. Many antibody drugs especially those targetting immune checkpoint proteins use the human IgG4 constant regions. As an ideal recombinant mouse IgG1 isotype control, the recombinant MOPC-21 mIgG1 kappa isotype control has low or no specific binding to any mouse sample, and completely mouse variable regions and the mouse IgG1 kappa constant regions. The mouse IgG1 kappa isotype control and mutants can be used in ELISA, Western blot (WB), the cell-based assay or animal model as the antibody negative control. Please contact us to ask for a quote for the engineered MOPC-21 mouse IgG1 isotype control mutants, mIgG1 isotype control and mutants with Avi-, His-, and Flag-tags, and biotinylated mIgG1 isotype control and mutants. A variety of conjugates (such as dyes and fluorophores) with the MOPC-21 mouse IgG1 isotype control and mutants are available.
