Monoclonal mouse IgG2a antibody against E. coli β-galactosidase for in vivo use

Anti-β-Gal-mIgG2a InvivoFit™ is a recombinant monoclonal antibody (mAb) comprising the variable region of the hybridoma-derived mAb Mouse IgG2a Control (clone: T9C6) that targets E. coli β-galactosidase (β-Gal).

This mAb does not react with murine proteins.

Anti-β-Gal-mIgG2a InvivoFit™ features the murine IgG2a isotype, a major immunoglobin present in serum. This isotype displays very high ADCP, high ADCC, and high CDC [1].

This mAb is provided as an isotype control in an InvivoFit™ grade for use with InvivoGen's IgG2a antibodies in the mouse anti-mouse mAbs collection.

It has been produced in CHO cells and purified by affinity chromatography with protein A.


Key features of Anti-β-Gal-mIgG2a InvivoFit™:

  • Sequence is 100% murine
  • Filter-sterilized (0.2 µm), endotoxin level < 1 EU/mg
  • Suitable for parenteral delivery in mice (azide-free)
  • Low aggregation < 5%
  • Produced in both animal-free facilities and defined media
