Cell Culture 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 10-50ug/ml. The plates are treated with the solution, at room temperature 1-2 hours, the supernatant removed and the plates rinsed with fresh media or buffer. Growth media is then added and the coated plates seeded with a suspension of freshly harvested cells. Care should be taken to inactivate serum proteases used in the preparation of the cells, since fibronectin is very sensitive to proteolysis. Optimum concentration of fibronectin depends on the types of cell and the particular surface used. Generally, use 1-5ug/cm? of growth surface.
Formulation
The Fibronectin was lyophilized from a concentrated 1mg/ml solution containing 0.05M Tris Cl pH-7.5 and 0.1M NaCl.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Greater than 95.0% as determined by SDS-PAGE.
Solubility
Purified fibronectin has a tendency to form insoluble aggregates upon reconstitution. We suggest to reconstittue the 1mg Fibronectin with a chaotropic agent such as urea at room temperature at a concentration of 0.2mg/ml using sterile water.
Let stand 1-2 hours.
Source
Human Plasma.
Stability
Lyophilized Fibronectin although stable at room temperature for 1 week, should be stored desiccated below -18¡ãC.
Upon reconstitution Fibronectin should be stored at 4¡ãC between 2-7 days and for future use below -18¡ãC.
Please prevent freeze-thaw cycles.
