Abstract
A recombinant ecarin protein that specifically activates prothrombin, said protein being efficiently prepared by the genetic engineering technique comprising the steps: (1) culturing a transformant microorganism or animal cell transformed with an expression vector in which a gene encoding ecarin is incorporated to the downstream of a promoter so as to produce and accumulate ecarin in culture supernatant or within said transformant and recovering the produced ecarin; and (2) purifying a solution containing the recovered ecarin to obtain purified ecarin. The present invention allows for production of recombinant ecarin on an industrial scale.
