Mechanism of Action

Information	Vemurafenib is a potent and selective BRAFV600E kinase inhibitor. It affects the MAPK/ERK signaling pathway by blocking MEK and ERK phosphorylation, effectively inhibiting cell proliferation and migration, and inducing apoptosis in BRAF-mutated cancer cells.

Frequently Asked Questions

Question 1:
How about its half-life?

Answer:
It was reported that this compound has a half-life of 57 hours.

Question 2:
When prepared in 4% DMSO/30% PEG 300/5% Tween 80/ddH2O solutions, it forms a pellet down the tube?

Answer:
When preparing this kind of vehicle, please dissolve it in DMSO clearly first. If it dissolves not readily, please sonicate and warm in the water bath at about 45 degree. Then add PEG and Tween. After they mixed homogeneously, then dilute with water.

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration _(start) x Volume _(start) = Concentration _(final) x Volume _(final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

*When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).
