Deionized or distilled water. 500 mL graduated cylinders. Test tubes for dilution.

Application Details

Application Notes: Before using Kit, spin tubes and bring down all components to bottom of tube. Duplicate well assay was recommended for both standard and sample testing.

Sample Volume: 100 μL

Plate: Pre-coated

Protocol: ELISA Kit is based on standard sandwich enzyme-linked immune-sorbent assay technology. An antibody has been precoated onto 96-well plates. Standards and test samples are added to the wells, a biotinylated detection antibody specific for target is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the target amount in sample captured in plate.

Target Details for IGFBP4

Target: IGFBP4 (Insulin-Like Growth Factor Binding Protein 4 (IGFBP4))

Alternative Name: IGFBP4

Background:

Background: Insulin-like growth factor-binding protein 4 is a protein that in humans is encoded by the IGFBP4gene. This gene is a member of the insulin-like growth factor binding protein (IGFBP) family and encodes a protein with an IGFBP domain and a thyroglobulin type-I domain. The protein binds both insulin-like growth factors (IGFs) I and II and circulates in the plasma in both glycosylated and non-glycosylated forms. Binding of this protein prolongs the half-life of the IGFs and alters their interaction with cell surface receptors. In addition, IGFBP-4 is a unique protein and it consistently inhibits several cancer cells in vivo and in vitro. Its inhibitory action has been shown in vivo in prostate and colon. It is secreted by all colon cancer cells.
