    • Disclosed in the present invention is a method for inducing the fusion of a dendritic cell with a tumour cell, in the fusion process, successively adding an amount of polyethylene glycol and collagen to induce cell fusion highly efficiently, wherein polyethylene glycol can make the lipid molecules of the plasma membrane at the contact point between the two cells disperse and recombine, and then the cells fuse due to the mutual affinity between the bilayer membranes at the interface of the two cells and the surface tension between each other. The collagen can retrench the cell membrane and repair the cell membrane after fusion, thereby forming stable fusion cells highly efficiently, so it is suitable for the production of specific biological products such as tumour vaccines and monoclonal antibodies etc.
    • 在本发明中公开了一种用于诱导树突状细胞与肿瘤细胞融合的方法,在融合过程中,依次加入一定量的聚乙二醇和胶原来高效诱导细胞融合,其中聚乙二醇可制成脂质分子 在两个细胞之间的接触点处的质膜分散和重组,然后由于在两个电池的界面处的双层膜之间的相互亲和力和彼此之间的表面张力而使细胞融合。 胶原蛋白可以缩短细胞膜并融合后修复细胞膜,从而高效形成稳定的融合细胞,适用于生产特定的生物制品,如肿瘤疫苗和单克隆抗体等。
