HDB-1

Customer Review

Based on 1 Customer Validation

HDB-1 is a selective inhibitor of the P2Y14 receptor (P2Y14R) with an IC₅₀ of 26 pM. HDB-1 shows no significant inhibition on P2Y1R, P2Y2R, P2Y4R, P2Y6R, and P2Y12R. HDB-1 blocks the activation of hepatic stellate cells (HSC) by inhibiting the PKA/Raf1/MEK/ERK signaling pathway mediated by P2Y14R, thereby alleviating the core pathological process of liver fibrosis. HDB-1 can be used for the study of liver fibrosis.

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.
