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. Reconstitution with sterile water or bacteriostatic water is straightforward, and the resulting solution should be used promptly or stored according to your protocol. We regularly supply university laboratories, contract research organizations and distributors, and can provide quantity-based quotations within one business day.
