Background: IGFBP-rp1/IGFBP-7

The superfamily of insulin-like growth factor (IGF) binding proteins include the six high-affinity IGF binding proteins (IGFBP) and at least four additional low-affinity binding proteins referred to as IGFBP related proteins (IGFBP-rP). All IGFBP superfamily members are cysteine-rich proteins with conserved cysteine residues, which are clustered in the amino- and carboxy-terminal thirds of the molecule. IGFBPs modulate the biological activities of IGF proteins. Some IGFBPs may also have intrinsic bioactivity that is independent of their ability to bind IGF proteins. Post-translational modifications of IGFBP, including glycosylation, phosphorylation and proteolysis, have been shown to modify the affinities of the binding proteins to IGF. ALS (Acid Labile Subunit) is a liver-derived protein that exists in a ternary complex with Insulin-like Growth Factor (IGF)-binding Protein-3 (IGFBP-3) or IGFBP-5, and either IGF-I or IGF-II. ALS increases the half-life of IGF/IGFBP complexes in circulation.

Human IGFBP-rp1/IGFBP-7 DuoSet ELISA
By Anonymous on 10/01/2020
Sample Tested: Urine

Fantastic performance. Remember this uses reagent kit 3 not 2 (most of the duosets I use require to 2) which messed me up at first. Used for human urine @ 1:500 dilution.

Human IGFBP-rp1/IGFBP-7 DuoSet ELISA
By Rambabu Surabattula on 09/13/2019
Sample Tested: Human serum

I used this kit for quantifying IGFBP7 in human serum. It works very well and easy to use protocol. I have used almost 6X 5kit so far.
