Fibronectin Human, Purified Protein is a native protein purified from Human plasma. It has a molecular weight of 440 kDa. APPLICATION: Fibronectin is useful for the induction of cell attachment to a variety of surfaces including plastic and glass tissue culture labware, petri dishes, coverslips, microcarrier beads, etc. Fibronectin is useful for growth and maintenance of cells in low serum conditions. In general, the reconstituted fibronectin should be diluted with sterile physiological saline or serum-free medium to a concentration of 10-50 ¿g/ml. PURITY: 95.0% or greater. FORMULATION: The Human Fibronectin was lyophilized from a non sterile 2 mg/ml buffer of 10mM sodium phosphate, pH 7.5 and 0.15M NaCl. OTHER NAMES: Cold insoluble globulin, FINC, LETS, MSF, FN.
