IGF-2 (insulin-like growth factor 2) is a 67-amino-acid single-chain polypeptide that signals through the IGF-1 receptor and the mannose-6-phosphate/IGF-2 receptor to regulate growth, differentiation and survival of cultured cells. It is a standard supplement in serum-free media and a reference protein in growth-factor signaling research. One of the more common reasons to stock this growth factor is to keep serum-free media reproducible, because a defined 67-amino-acid sequence removes the batch drift you get from undefined serum. In practice, it gets used when investigators need a consistent mitogenic signal across many plates, and the mannose-6-phosphate receptor engagement adds a second angle for receptor-cross-talk studies. Researchers tend to reach for it as a clean alternative to crude serum supplements in differentiation and survival assays. We supply it with HPLC-verified purity, keep a traceable lot history, and can set aside the same batch for large screening runs so the whole experiment draws on one source. Supply of this growth factor is handled with traceability in mind, and each order carries the purity report and handling guidance. For screening runs we can set aside the same lot so all plates draw on one source, and delivery is arranged within recommended conditions. Multi-gram quantities are available for long experiments. With a stable supply chain and strict quality control, we serve research teams and distributors in many countries. Every parcel is professionally packed and tracked, and we provide timely communication from order to delivery, plus after-sales support.
