CD40LG and Hodgkins lymphoma: To test QC cloning with a variety of targets, we cloned the variable regions of the heavy and light chains of immunoglobulins expressed in two non-Hodgkin lymphoma biopsy samples: T109, which contains a tumor-associated immunoglobulin of the isotype IgG,L (heavy chain Gamma, light chain Lambda), and T069, with the isotype IgM,K (heavy chain Mu, light chain Kappa).
