β-galactosidase antibody; Mouse IgG2a isotype control
Recombinant mouse IgG2a isotype control mAb against E. coli β-galactosidase
InvivoGen’s Anti-β-Gal-mIgG2a InvivoFit™ antibody
InvivoGen provides a recombinant anti-β-Gal-mIgG2a monoclonal antibody (mAb). It is expressed and produced in chinese hamster ovary (CHO) cells, ensuring reliability and lot-to-lot reproducibility. Thereby, common hybridoma-related drawbacks such as the generation of non-relevant mAbs containing aberrant light chains are avoided. This control antibody targets E. coli's β-galactosidase (β-Gal), an antigen that is not present in mice. In addition, it displays very high ADCP (antibody-dependent cell-mediated phagocytosis), high ADCC (antibody-dependent cell-mediated cytotoxicity) and high CDC (complement-dependent cytotoxicity) effector functions .
The sequence of Anti-β-Gal-mIgG2a InvivoFit™ is 100% murine (constant and variable regions), as the original clone (clone T9C6) was raised in mice using a proprietary method. This feature allows for reduced immunogenicity and risks of fatal hypersensitivity reactions upon repeated mAb injections into mice .
Anti-β-Gal-mIgG2a InvivoFit™ is provided in the InvivoFit™ grade, suitable for in vivo studies. All InvivoFit™ products are handled in a clean room, filter-sterilized, and tested for bacterial contaminants. Additionally, this grade guarantees low levels of endotoxins (<1 EU/ml). The buffer formulation is specifically adapted for in vivo studies.

InvivoFit™ is a high-quality standard specifically adapted for in vivo studies. InvivoFit™ products are filter-sterilized (0.2 µm) and filled under strict aseptic conditions in a clean room. The level of bacterial contaminants (endotoxins and lipoproteins) in each lot is verified using a LAL assay and a TLR2 and TLR4 reporter assay.Back to the top
