Fig. 4From: Optimization of recombinant antibody production based on the vector design and the level of metabolites for generation of Ig- producing stable cell linesSelection of subclones for developing stable cell lines by IgG production, cell concentration, and metabolic selection. IgG productivity was determined by ELISA. Level of lactate production and ammonia concentration for selected subclones 5B11/C12 and 7D2/G11was determined by commercial kitsBack to article page
