Popis: | Immunoglobulin (Ig) and T-cell receptor (TCR) gene rearrangement (GR) studies have been successfully employed to investigate the clonality and cell lineage of various lymphoid malignancies. Several lymphoma cell lines, such as BJAB, RAJI, DG75 and Jurkat cell lines, were often used as the positive controls in GR detection assays. Of those, the DG75 B-cell lymphoma line was found to exhibit biclonality [two or more homoduplex and heteroduplex bands in a polymerase chain reaction (PCR) product of clonality assay] in the PCR of GR detection assays. To further explore these characteristics of the biclonal phenomenon, the PCR products were purified and cloned into a pEGM-T clone vector. The sequences were analyzed using DNA analysis software. The results demonstrated that the two bands originated from two forms of GR of DG75 cell lines, i.e., DG75 is a biclonal cell line in Ig GRs, which has not been reported before. |
