Recombinant Mouse PIGF-2

Placenta growth factor 2 (PlGF-2) is an isoform of PlGF¹ and a member of the vascular endothelial growth factor (VEGF) family. PlGF-2 has heparin binding properties and Neuropilin-1 is a receptor for PlGF-2.

The biological activity of Mouse PlGF-2 was determined by its ability to bind rmFlt-1/Fc in a functional ELISA. Immobilized rmFlt-1/Fc at 2 μg/ml (100 μL/well) can bind rmPlGF-2 with a linear range of 0.1 - 5 ng/ml.

Lyophilized

The predicted molecular weight of Recombinant Mouse PlGF-2 is Mr 15.1 kDa. However, the actual molecular weight as observed by migration on SDS-PAGE is Mr 19-22 kDa.

15.1

This recombinant protein was lyophilized from a 0.2 μm filtered solution in 35% acetonitrile (CH₃CN) and 0.1% trifluoroacetic acid (TFA).

This lyophilized protein is stable for six to twelve months when stored desiccated at -20°C to -70°C. After aseptic reconstitution, this protein may be stored at 2°C to 8°C for one month or at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. See Product Insert for exact lot specific storage instructions.
