Purification
Greater than 98% by SDS-PAGE and HPLC
Bio-Activity
Determined by its ability to stimulate the proliferation of human ANBL-6 cells. The expected ED50 is <=0.5 ng/ml, corresponding to a specific activity of >=2 x10^6 units/mg.
Endotoxin
Less than 0.1 ng/µg of protein (less than 1EU/µg).
Presentation
Sterile filtered, lyophilized from 10 mM sodium phosphate, pH 7.6
Reconstitution
Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. 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.
Storage
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.
Restrictions
For research use only. Intended for use by laboratory professionals.
