Effect of B-CLL cells obtained from 3 different patients on in vivo antigen-induced B cells capable of IgG-tet secretion obtained from the blood of 3 different healthy volunteers who had been immunized with tet 6 days earlier.
Blood B cells (5 × 105 cells/mL) were cultured in the absence and in the presence of increasing numbers of B-CLL cells for 7 days. IgG-tet secreted into the culture supernatant was determined by ELISA.
