Formulation:

Lyophilized from a sterile filtered (through a 0.2 �m filter) solution without additives.

Purity:

>95% by SDS-PAGE analysis.

Biological Activity:

ED50: 1 to 4 ng/ml (determined by measuring the dosedependent proliferation of human TF-1 cells. A concentration range of 0.1 to 10.0 ng/ml is effective for most in vitro applications. The optimal concentration should be determined for each specific appli
