• CDK9 inhibitor (A3294): Practical Lab Guide

  2026-08-13

  CDK9 inhibitor (A3294) is a selective serine/threonine kinase inhibitor for studying CDK9-dependent transcription elongation and P-TEFb-related processes. It is appropriate for focused biochemical, cell viability, and MT4 HIV-1 research workflows, but not for broad-spectrum CDK inhibition or long-term storage of prepared solutions.
