Cbl-b-IN-29

Cbl-b-IN-29 is an orally active CBL-B inhibitor. Cbl-b-IN-29 binds to the CBL-B active pocket. Cbl-b-IN-29 induces Jurkat cell release IL-2 with an EC₅₀ of 159 nM, effectively inhibiting the function of immune E3 ubiquitin ligase. Cbl-b-IN-29 demonstrates robust anti-tumor efficacy in vivo with good tolerability and no observed adverse reactions. Cbl-b-IN-29 can be used for cancer immunotherapy, colorectal cancer and immune-oncology combination research.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
