HEK 293 Cells

Human

Greater than 95% by SDS-PAGE and HPLC

Recombinant Human Vitronectin promotes attachment of hESC and iPSC in serum-free, feeder conditions at 5 µg/ml.

Less than 0.1 ng/µg of protein (less than 1EU/µg).

Sterile filtered, lyophilized from 20 mM sodium phosphate, pH 7.5

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. For extended storage it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.

If lyophilized, can be stored for 1 month at room temperature, 6 months at 4°C, or through the expiration date at -20°C to -80°C. Once reconstituted per the supplied instructions, can be stored for 3 months at -20°C to -80°C, or for 1 week at 2°C to 8°C. Avoid freeze-thaw cycles.
