To the group. I am going to study the clonality of lymphoma using x-linked probes and I need your help. 1. Does anyone happen to know the sequence of M27 beta? Is is PCR-able? 2. Does anyone have the experience using PCR to amplify HPRT for clonality analysis? Would you please tell me the reference. Cheers. Dr Peng HZ UCL Medical School RMKDHHP at UCL.AC.UCL
