Abstract
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.
