WebJun 1, 2024 · Cutaneous lymphomas, both B-cell and T-cell, are not uncommonly seen in the skin, but those lymphomas exhibiting clonality for both B-cell and T-cell populations are scarce. Characterization of dual receptor rearrangement as primary composite lymphoma versus primary lymphoma with reactionary respons … WebB-cell clonality is determined by PCR and fragment sizing analysis of fluorescently labeled products. Master mixes are commercially provided by InVivoScribe in a BIOMED-2 Assay for IgH and IgK. Patterns consistent with polyclonal, oligoclonal and monoclonal B-cell populations are interpreted from fragment-sizing electropherograms.

WebAug 5, 2016 · B cells are a type of cells that produce antibodies. Each B cell produces a different type of antibody. For example, consider the following B cells: C1, C2, and C3, which produce antibodies A1, A2, and A3, respectively. We are dealing with 3 B cell clones, given that they produce 3 different types of antibodies. http://cancergeneticslab.ca/hematological/lymphoma/nhl-clonality/
