Proteins for hematological cancer targets

With the newly FDA approved adoptive T-cell therapies, Kymriah and Yescarta, targeted on CD19, there are treatment solutions for a number of previously incurable B cell malignant diseases. In the meantime, new cancerous targets are the hot list for CAR T-cell therapy development.

Therapeutic antibodies need to exert their functional activities in human body. Therefore, it is very critical to identify monoclonal antibodies with functional activities. “Garbage in Garbage out” is the rule of thumb for therapeutic antibody development. DIMA Biotechnology LTD pays special attention on its immunogen development process. All the proteins were made by using HEK293 mammalian cell secretion expression system and we implemented a strict quality control process, including purity testing, antibody-drug interaction verification, freezing and thawing Tests, thermal stability tests, etc. In order to meet the needs, DIMA Biotechnology LTD provide a full spectrum of functional proteins of new CAR T-cell targets.

Product targets:

CD138BCMAGPRC5DCS1CD37CD7
FLT3CD123CD30CD5CD30-LCD34
