Professors from Tsinghua University proved Heat Shock Proteins 90α（Hsp90α）as the biomark for tumours for the first time. And the Quantitative Testing Reagent Kit for Hsp90α has passed clinical test and been approved by China and EU.

 It is been found that Hsp90α can be produced by cancer cells. And Hsp90α can be used as a biomark to test various cancer. The reagent kit, compared with regular methods, is cheaper and much more efficient.
