Recombinant full length human insulin-like growth factor binding protein 1, expressed in Escherichia coli.
Localization:
Secreted
Species Reactivity:
Cross-reacts with Human. Not yet tested in other species.
Applications:
Uses:
ELISA: Use at a concentration of 2 ug/ml. In the ELISA capture assay, plates are coated with 100 ul/well of the capture antibody (2 ug/ml) in combination with 100 ul/well of a detection antibody (affinity-purified biotinylated polyclonal anti-human IGFBP1 antibody at 100 ng/ml). An ELISA range of 62.4 to 4000 pg/ml may be obtained. Neut: Use at a concentration of 10 - 40 ug/ml. The Neutralization Dose50 (ND50) for this antibody is 10-40 ug/ml in the presence of approximately 5 ug/ml of recombinant human IGFBP1 and approximately 6 ng/mL of recombinant human IGF1, using human MCF7 cells. WB: Use at a concentration of 1-2 ug/ml. The detection limit for recombinant human IGFBP1 is approximately 0.5 ng/lane under non-reducing conditions. ot tested in other applications. Optimal dilutions/concentrations should be determined by the end user.

Insulin-like growth factor binding protein-1 (IGFBP-1) is a member of the superfamily of insulin-like growth factor (IGF) binding proteins which include six high-affinity IGF binding proteins (IGFBP) and at least four low-affinity binding proteins referred to as IGFBP related proteins (IGFBP-rP). The IGFBP members are cysteine-rich proteins with conserved cysteine residues, clustered in the amino-terminal and the carboxyterminal regions of the molecule. Contained within IGFBP-1 and
