Provided by the present invention are an anti-coagulant comprising a polysaccharide having a structural unit in which an abundance ratio of glucose, glucuronic acid and rhamnose is 2:1:1 mole, preferably a polysaccharide having a structural unit represented by Formula (1) and more preferably a compound obtained by partially sulfating a hydroxyl group of gellan and an anti-thrombus agent or a blood contact face-treating agent for medical equipment comprising this anti-coagulant.
摘要:
This invention provides a selective cellular fibronectin (cFN) adsorbent utilizing a nonwoven cellulose sulfate fabric and a method for fractional purification of FN which-comprises contacting an FN matter containing both plasma fibronectin (pFN) and cellular fibronectin (cFN) with the nonwoven cellulose sulfate fabric to separate pFN and cFN from each other. By the fractional purification method of the invention, cFN and pFN can be fractionated in an expedient manner and with high efficiency and both pFN and cFN can be recovered in high purity and good yield.
