For recombinant antibody production, stable cell lines such as the Chinese hamster ovary (CHO) cells, human embryonic kidney 293 (HEK293), or NS0 murine myeloma cells are more commonly employed. (sigmaaldrich.com)
The induced IgG and IgM antibodies were able to stimulate various Fc-mediated effector mechanisms associated with protection against malaria, including phagocytosis, release of reactive oxygen species, production of IFN-γ as well as complement activation and fixation. (nature.com)
We report that the variable domains of recombinant HIV-1 Env immunogens activate a large number of B cell clones that give rise to many non-neutralizing antibodies, and that removing the variable domains from the immunogen reduces the number of activated B cell lineages and leads to the development of autologous neutralizing antibodies, a step towards bNAb-production.

The researchers published the findings of their study-which was based on an internally-developed antibody test-in Science . (darkdaily.com)
