General description

Human Insulin-like Growth Factor II (IGFII) contains 67 amino acids and shares similar structural features with IGFI, including a 62% sequence homology. In human plasma, IGFI and IGFII are associated with IGF-binding proteins that transport the polypeptides and partially regulate their actions in vivo. In addition to the insulin receptor, IGFII binds to two forms of IGF receptors, both of which are widely distributed in different tissues and cultured cells. IGFII is mitogenic for a variety of cultured cells, including mouse 3T3 cells,12 normal rat kidney cells, human or chicken fibroblasts and MCF-7 human breast carcinoma cells.


Less than 10% cross-reactivity to human IGF-I (Tanaka, H, 1989; Suzuki, T, 1989).
This antibody detects IGF-II.


Partially purified rat IGF-II. Clone S1F2


Detect IGF-II using this Anti-IGF-II Antibody, clone S1F2 validated for use in ELISA, IP, IC, NEUT & WB.
Neutralization: 10 μg/mL of a previous lot inhibited the stimulatory effects of IGF-II (10 ng/mL) on DNA synthesis in chicken embryo fibroblasts. Cell viability was assessed using an ATP endpoint assay (ATPLiteÔ-M, Packard Instruments). Previous lots of antibody were tested to inhibit IGF-II-dependent incorporation of [3H]-thymidine

Purpose: Myxoid liposarcoma is an aggressive disease with particular propensity to develop hematogenic metastases. Over 90% of myxoid liposarcoma are characterized by a reciprocal t(12;16)(q13;p11) translocation. The resulting chimeric FUS-DDIT3 fusion protein plays a crucial role in myxoid liposarcoma pathogenesis;
