摘要: DNA amplification by polymerase chain reaction (PCR) with primers designed on the widely distributed Alu sequences allows production of specific inter-Alu DNA-fingerprints. Amplification tumour and matched normal can show differences due to genetic alterations within genome. We applied this approach study low-grade extranodal marginal zone B-cell lymphoma (of MALT type). After digestion restriction enzymes, samples were separately amplified PCR three different Alu-primers. A comparison between fingerprint pattern from was made. Inter-Alu bands differing two excised gel, cloned sequenced. Nine cases MALT-lymphomas have been analysed, giving seventeen normal. sequence analysis showed identities for them available at GenBank. The methodology Alu-PCR detect DNA-based abnormalities, in addition or combination R...
