Accelerating Switchable and
Modular CAR-T Research
with Premium Proteins
|
|
Switchable and modular CAR-T therapies, now in IND-cleared clinical trials for autoimmune diseases and solid tumors, represent a transformative advance in cell therapy. By utilizing adapter molecules to guide CAR-T cells to specific antigens, this approach enables external control, flexible multi-targeting, and enhanced safety. Compared to traditional CAR-T, it reduces off-target effects, offering greater adaptability across both hematologic and solid malignancies. Sino Biological offers a comprehensive portfolio of switchable and modular CAR-T development solutions, featuring newly launched, endotoxin-free recombinant proteins such as B7-H3, BCMA, and HER2 to accelerate your research with high purity and consistency.
