One-Stop CAR-B Therapy Development

Over the past decade, great progress has been made in the field of immunotherapy, especially in the field of T cell therapy. Chimeric antigen receptor (CAR)-engineered T cell therapy is the most promising approach, which has shown remarkable ability in the elimination of a variety of tumors. While, as more studies focused on B cells, researchers have found that the engineered B cells also have great therapeutic potential in various diseases.

Based on advanced technology and years of research, Creative Biolabs has developed high-quality custom services covering the entire CAR-B therapy development process to best suit customer's technical, program, and budget requirements which can greatly assist customer's research, preclinical investigation, and clinical stage development.

Our CAR-B therapy development services harness the power of two main advantages:

Gene delivery:

As the best pseudotype candidate, using the LVs pseudotyped with the BaEV envelope to achieve efficient B-cell gene transfer, which can facilitate efficient transduction of resting and stimulated human B cells. This system will be useful in B cell lines, and the range of alternative glycoproteins can be screened for optimal infectivity.

CRISPR-Cas9-mediated replacement of endogenous antibodies with engineered emAbs targeting RSV, HIV-1, influenza, or EBV in primary human B cells.

B cell genome engineering:

CRISPR/Cas9 system has been widely used in recent years due to its advantages of high specificity, high activity, and simple design. The CRISPR design algorithms will be used to develop effective knock-out strategies to remove endogenous BCR (B cell receptor) expression from a B cell line.
