a, b, c Cell morphology of murine myeloma Ag8 (a), hybridoma Hyb H12 ab- (b) and hybridoma Hyb CN-13 ab + (c) with phase contrast microscopy at 200× magnification in cell culture. The cells are growing in suspension in medium RPMI 1640 (Methods). Under these conditions Ag8 myeloma and hybridoma Hyb H12 ab- cells form clumps of loosely attached cells, while all hybridoma Hyb CN-13 ab + are settled on the bottom of the culture dish
