Determined by the dosedependent stimulation of the proliferation of human umbilical vein endothelial cells (HUVEC) using a concentration range of 4.0-8.0 ng/mL.
Activity assay SDS-PAGE The optimal working dilution should be determined by the end user.
Lyophilized from sterile solution with no additives
Store at -20°C. Reconstitute in water to a concentration of 0.1-1.0 mg/mL. Do not vortex. For extended storage, to further dilute in buffer containing carrier protein (e.g. 0.1% BSA) and store in aliquots at -20°C to -80°C is recommended.
