LR3IGF-I, Human, Rapid™ ELISA assay-1 Plate Kit

Human LR3 insulin-like Growth Factor-I (LR3IGF-I) was developed by GroPep Bioreagents (www.gropep.com) specifically for supplementation of mammalian cell culture to support the survival and proliferation of cells. It is engineered to have a higher biological potency than native IGF-I or IGF-II and has several advantages over recombinant insulin. Supplementation of cell cultures with LR3IGF-I at a much lower concentration results in equivalent or better productivity than supplementation with standard concentrations of insulin. LR3IGF-I is better able to stimulate the type I IGF receptor and thus induce a higher level of activation of intracellular signalling molecules, which are responsible for promoting cell survival by inhibition of apoptosis.

This LR3IGF-I Rapid ELISA kit combines GroPep's many years of expertise in the field of IGF research and Biosensis' newly established Rapid ELISA platform. This collaboration has resulted in the new LR3IGF-I Rapid ELISA kit, which provides for the sensitive, specific and reliable quantification of LR3IGF-I protein in less than 3 hours!

The ELISA kit consists of a complete set of reagents and pre-coated plate to allow immediate assay of LR3IGF-I in culture media. Included in the kit are mouse monoclonal anti- LR3IGF-I capture antibody pre-coated onto an ELISA plate, standard LR3IGF-I protein, a biotinylated anti- LR3IGF-I detection antibody and horseradish peroxidase (HRP)-conjugated streptavidin. The addition of a substrate (3,3',5,5'-tetramethylbenzidine, TMB) yields a colored reaction product which is directly proportional to the concentration of LR3IGF-I present in samples and the supplied protein standard.

This LR3IGF-I Rapid ELISA kit has been developed, optimized and validated to quantify LR3IGF-I protein in cell culture medium. It is likely to be used to measure LR3IGF-I in media and during downstream processing of media following a production cycle and is not intended for other use. This kit has been configured for research use only and is not to be used in diagnostic or clinical procedures.
