Assessment of intracellular light and heavy chain polypeptides by flow cytometry. a cell pools. b cell mini-pools. Intracellular light and heavy chains polypeptides of ethanol fixed cells were measured using a FITC-labeled goat anti-human kappa light chain antibody and a FITC-labeled goat anti-human IgG (γ chain specific) antibody, respectively.
