Human Matrix metalloproteinase 9/Gelatinase B (MMP-9) ELISA Kit | KTE62621

Product Overwiew:

This Human Matrix metalloproteinase 9/Gelatinase B (MMP-9) ELISA Kit employs a two-site sandwich ELISA to quantitate MMP9.

Background:

MMP-9 (also known as gelatinase B) is secreted as a 92 kDa zymogen. Cleavage of pro-MMP-9 at or near residue 87 results in the active enzyme with a mass of approximately 82 kDa. MMP-9 has three fibronectin type II domains, a hemopexin-like domain and a proline-rich type V collagen-homologous domain.Pro-MMP-9 can be activated by MMP-3 or by certain bacterial proteinases. MMP-9 is inhibited byα2-macroglobulin or by TIMP-1, which binds to pro-MMP-9 as well as to active MMP-9.Pro-MMP-9 is secreted by monocytes, macrophages, neutrophils, keratinocytes, fibroblasts, osteoclasts, chondrocytes, skeletal muscle satellite cells, endothelial cells, and various tumor cells. Pro-MMP-9 expression is upregulated by TGF-β1, IL-1β, TGF-α, PDGF-AB,

Application:

This Human Matrix metalloproteinase 9/Gelatinase B (MMP-9) ELISA Kit employs a two-site sandwich ELISA to quantitate MMP9 in samples. An antibody specific for MMP9 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyMMP9 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for MMP9 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of MMP9 bound in the initial step. The color development is stopped and the intensity of the color is measured.

Used for:

ELISA

Features & Benefits:

Human Matrix metalloproteinase 9/Gelatinase B (MMP-9) ELISA Kit has high sensitivity and excellent specificity for detection of Human MMP9. No significant cross-reactivity or interference between Human MMP9 and analogues was observed.

Usage Notes:

• Do not mix components from different kit lots or use reagents beyond the kit expiration date.
• Allow all reagents to warm to room temperature for at least 30 minutes before opening.
• Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination.
• Unused wells must be kept desiccated at 4 °C in the sealed bag provided.
• Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes.
• It is recommended that all samples and standards be assayed in duplicate or triplicate.
