Featured product from Qkine


Recombinant human vascular endothelial growth factor 165 (also known as VEGF165/ VEGF-165/ VEGF-A/ VEGF165) protein is widely used in culturing primary endothelial cells (ECs), such as human umbilical vein endothelial cells (HUVEC), under serum-free conditions for blood vessel developmental studies. VEGF 165 is commonly used with human-induced pluripotent stem cells (hiPSC) or embryonic stem cells (ESC)-derived EC for developing human vascular tissue models for disease mechanism studies. VEGF-165 has many applications including its use in neural research involving oligodendrocyte precursor cells, Schwann cells, astrocytes, and microglia. It plays a role in bone formation, regulates mesenchymal stem cell differentiation, and serves as a survival factor for chondrocytes, hematopoietic stem cells, and tumor cells.

A highly bioactive 38 kDa homodimer, which is animal-derived component-free (ADCF) and carrier protein-free (CF).
