Product Overview

Description: Human insulin like growth factor binding protein 2 (IGFBP-2) ELISA kit (0.156-10 ng/mL) is an ELISA-based in vitro research tool designed specifically for the quantitative detection of IGFBP-2 in human samples with a range of 0.156-10 ng/mL and a minimum detectable dose (sensitivity) of 0.062 ng/mL. The kit is highly sensitive and easy to use.

Assay Principle: This kit utilizes a sandwich enzyme immunoassay technique. A microplate is pre-coated with a capture antibody specific to IGFBP-2. Standards or samples are introduced into the wells along with a biotin-conjugated detection antibody. This process forms a "sandwich" complex, effectively capturing any IGFBP-2 present in the specimen. After incubation, an avidin-HRP conjugate is added to each well. A final wash step removes all unbound components before the addition of a TMB substrate solution. The resulting colorimetric change is measured spectrophotometrically at 450 nm ± 10 nm after the enzymatic reaction is terminated with a sulfuric acid solution. The concentration of IGFBP-2 in the samples is then determined by comparing their absorbance (O.D.) to a standard curve.

Background: IGFBP-2 is a multifunctional molecule that plays a crucial role in human growth, metabolism, and cellular processes by regulating the biological activity of insulin-like growth factors (IGFs). Primarily through binding to IGF proteins, IGFBP-2 prolongs their half-life in the body and modulates their interactions with cell surface receptors, thereby inhibiting or enhancing the pro-growth effects of IGFs. The role of IGFBP-2 in obesity has garnered increasing attention. Its reduced levels are closely associated with obesity, dyslipidemia, and insulin resistance.

Synonyms: IBP-2; IGF-binding protein 2; IGFBP2; BP2, IBP2; Insulin-Like Growth Factor Binding Protein 2, 36kDa; Insulin-Like Growth Factor-Binding Protein 2

Applications: Human insulin like growth factor binding protein 2 (IGFBP-2) ELISA kit (0.156-10 ng/mL) is used to quantify IGFBP-2 in serum, plasma, urine, tissue homogenates, and other biological fluids of humans, providing data to support research in a wide range of areas, including immunity, endocrinology, signal transduction, obesity, and others.
