Recombinant mAbs for SARS-CoV-2 Research 

Monoclonal antibodies (mAbs) against SARS-CoV-2 antigens or host pro-inflammatory cytokine receptors are under therapeutic investigation for fighting COVID-19. InvivoGen offers isotype families of recombinant mAbs related to COVID-19 research.



These antibodies are available with different immunoglobulin isotypes, either native or engineered. The different isotypes can trigger or hinder mAb effector functions including, complement-dependent cytotoxicity (CDC) and antibody-dependent cellular cytotoxicity (ADCC). Depending on your target and application, InvivoGen offers:

  • Human isotypes

hIgG1: highly-represented in the serum and a potent inducer of ADCC and CDC
hIgG1NQ: non-glycosylated hIgG1 exhibiting ablated ADCC and severely compromised CDC
hIgA: main antibody isotype present in mucosal secretions (i.e. in the respiratory tract) and a moderate inducer of ADCC
hIgM: first antibody isotype raised in the immune response and a potent inducer of CDC

  • Mouse isotypes

mIgG2a: most potent inducer of ADCC and CDC among murine isotypes
mIgG1e3: effectorless mIgG1 with a D265A point mutation


As a guarantee of quality, our antibody constructs are fully sequenced and their target binding has been validated.

InvivoGen’s products are for research use only, and not for clinical or veterinary use.
