Creative Biolabs provides comprehensive technical support for the CD276 recombinant antibody products, including assistance with experimental design, optimization of assay conditions, troubleshooting, and data analysis. Our team of experienced scientists is available to answer any inquiries regarding product usage, storage, and handling, ensuring that researchers can effectively utilize the antibody for their experiments. Additionally, we also offer validation data and recommended protocols to aid researchers in obtaining reliable and reproducible results with the antibody.
The CD276 protein (B7-H3) is a promising target for disease treatment due to its roles in regulating the immune response and promoting tumor growth. When CD276 binds to its receptor on T cells, it can inhibit their activity and suppress the immune response, which can be beneficial in autoimmune diseases where the immune system is overactive. Besides, CD276 is also overexpressed in many types of cancer, where it promotes tumor growth and evasion of the immune system. In these cases, targeting CD276 can help enhance the anti-tumor immune response and inhibit tumor growth.
Our anti-CD276 recombinant antibody products are monoclonal antibodies that specifically target and block the CD276 protein. These recombinant antibodies are engineered for increased potency and specificity, making them valuable research tools for studying the role of CD276 in cancer development and potentially for developing targeted cancer therapies. Our list of anti-CD276 recombinant antibody products includes a variety of formulations and conjugation options to suit different experimental needs.
