IGF-2 (insulin-like growth factor-2) is a 67-amino-acid growth factor structurally related to insulin, signaling through the IGF-1 receptor and IGF-2 receptor to regulate cell growth, differentiation and survival in research models. It is supplied as a high-purity white lyophilized powder at >=99% HPLC purity in sealed vials, offering good stability and easy reconstitution. It is applied in developmental biology, cell-culture studies, cancer research and growth-signaling pathway investigations, and serves as a key reference in growth-factor research. Every manufacturing run is QC-checked and batch-specific analysis reports are provided on request. Unopened vials should be kept sealed at 2-8 degree C away from light and moisture, and for longer-term storage -20 degree C is advised while minimizing freeze-thaw exposure. We welcome both sample orders and large quantities, and offer OEM, private-label and secure neutral packing for international shipping. For laboratory research use only.
