3.CONCLUSION: Using a PTD mediated antigen transduction system, exogenous BCR/ABL antigen can be transferred into APCs and be processed and presented onto surface of APCs to activate Ag specific CD8 + and CD4 + T cells in vitro . The strategy outlined in this paper may provide a new approach for priming Ag specific CD8 + and CD4 + T cells in vitro and immunotherapy of CML.
9.In this experimental research,it is introduced that a 5kW CO 2 laser with transverse flow for cladding Ni base alloy coat on austenite basic of the sealing surface of medium and high pressure valve for petrochemical industry. After processed by the laser cladding,the laser cladding coat of 3mm thick can be mede with a smooth surface.
