Humanized

Human

Detects human CD20. This non-therapeutic antibody uses the same variable region sequence as the therapeutic antibody Ofatumumab. This oaftumumab biosimilar is for research use only.

This monoclonal antibody was purified using multi-step affinity chromatography methods such as Protein A or G depending on the species and isotype.

Ofatumumab biosimilar is an IgG1κ human monoclonal antibody with a molecular weight of approximately 149 kDa. The antibody is produced in a recombinant CHO cell line using standard mammalian cell cultivation and purification technologies.
