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. Each vial holds a white lyophilized powder at >=99% HPLC purity. Detailed product documentation, flexible pack sizes and global shipping options support both academic and industrial workflows. IGF-2 is used in growth-factor research where insulin-like signaling, cell proliferation and differentiation pathways are investigated in multiple cell systems, and its cross-reactivity with insulin receptors makes it an important comparator in receptor-binding studies. Investigators typically dose the peptide in serum-free media and measure phosphorylation cascades, proliferation indices and phenotypic changes over defined intervals. The lyophilized material reconstitutes readily in dilute acid or buffer, and our batch documentation supports consistent experimental conditions. We offer flexible pack sizes for dose-response work and larger supplies for extended culture studies, and our team can advise on reconstitution and storage that preserve bioactivity for research use. When designing receptor-competition assays, investigators often compare this growth factor against insulin and IGF-1, so lot-to-lot consistency matters, and our batch records make those comparisons reproducible. We also provide guidance on the dilute-acid reconstitution that minimizes aggregation, and our packing protects the lyophilized material during international shipping. Bulk quantities support extended culture programs, and our support team answers technical questions about formulation and storage throughout the ordering process. 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.
