I'm studying at Dalian Medical University in China. I 'm working on CAR-T cells now. And I have the antigen and the antibody. I want to choose a company to obtain custom CAR-T cell generation, or just get the synthesis and cloning of an scFv with selected CAR domains into a lentivirus vector. I have no idea how to choose a good company and which company should I believe. Because the quality of the generation is very important. I have no experience in these companies. This company can be in China or other countries. Hope someone can help me and give me some advice, I will be very grateful. Thank you.
