Insulin-Like Growth Factor Binding Protein 7 (IGFBP7), recombinant human protein is supplied as a lyophilized powder. It is suitable for use in protein studies such as protein structure analysis and protein-protein interactions. In general, recombinant proteins can also be used as an immunogen, as a protein standard, or in cell biology research applications.

This recombinant protein was expressed from a DNA sequence encoding the human IGFBP7 (Q16270) (Met 1-Leu 282) fused to the Fc region of human IgG1 at the C-terminus.

Activity: Measured by its binding ability in a functional ELISA.
1. Immobilized IGFBP7 at 20 µg/ml (100 µl/well) can bind biotinylated human IGF2. The EC₅₀ of biotinylated human IGF2 is 0.06 µg/ml.
2. Immobilized human CCL21 at 2 µg/ml (100 µl/well) can bind human IGFBP7 with a linear ranger of 0.16-4 µg/ml.

Formulation: Lyophilized in 140 mM NaCl, 2.7 mM KCl, 10 mM Na₂HPO₄, 1.8 mM KH₂PO₄, pH 7.4, 5% Mannitol, 5% Trehalose, 0.02% Tween 80.

Reconstitution: Dissolve the protein in sterile double distilled water to a concentration of 25 mg/ml or lower. It is recommended that the protein be aliquoted and be used as soon as possible. Store aliquots under sterile conditions at -20°C. Avoid repeated freeze-thaw cycles.

Expiration Date: Expires one year from date of receipt when stored as instructed.
