Prepared from fresh frozen human plasma. Human Factor XI is a two-chain glycoprotein with molecular weight of 160,000 daltons. The two chains are identical disulfide bonded polypeptides with molecular weights of 80,000 daltons. Factor XI is activated to Factor XIa by Factor Xlla. Purity of Factor XI is assessed by SDS-PAGE. Activity is determined by clotting assay.
The above protein was purified from Human plasma units that test negative for antibodies to HBc, HCV, HIV 1/2, HTLV-I/II, and non reactive for HBsAg, HIV-1 RNA, HCV RNA, HBV DNA and Syphilis by FDA approved tests. Donors are screened for CJD.
