Product List

Creative Biolabs has successfully developed plenty of anti-CD276 CART related products to support global customers’ projects. We are pleased to receive any inquiries about the anti-CD276 CART development, please do not hesitate to get reach to us.

Background

B7-H3 (CD276) is a member of the B7 family that plays an important role in immune regulation in the T cell response, serving as a potential target for tumor immunotherapy. Studies have shown that B7-H3 participates in several key processes, such as inhibiting T cell activation and expansion, taking part in tumor immune escape, and affecting the immune responses and tumor manifestations. Abnormal B7-H3 expression is present in various tumor types, and is related to poor prognosis. B7H3-targeted immunotherapy will be a promising approach for disease treatment.

Anti-CD276 CAR-T In Vivo Assays

Efficacy Test of Anti-B7H3 CAR-T

To accelerate the CART development, we have established various mouse models and developed several in vivo experimental platforms to assess the efficacy of CAR-T cells to support customers' projects. Our mouse models include but are not limited to cell line-derived xenografted (CDX) models, and patient-derived xenografted (PDX) models, patient-derived organoid models for customers to choose from.

Toxicity Evaluation Anti-CD276 CAR-T

Toxicity testing is a necessary step in the in vivo evaluation process for CART development. The results of toxicity testing often give us more safety considerations for CAR-T cells. At Creative Biolabs, we offer a variety of methods for relevant detection to assess the treatment effect, such as H&E staining analysis of major organs in animal models treated with CAR-T cells.
