Product Description
Human Anti-tissue transglutaminase IgA (IgA-tTG) ELISA Kit | KTE62552 | Abbkine
Application: This Human Anti-tissue transglutaminase IgA (IgA-tTG) ELISA Kit employs a two-site sandwich ELISA to quantitate IgA-tTG in samples. An antibody specific for IgA-tTG has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyIgA-tTG present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for IgA-tTG 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 IgA-tTG bound in the initial step. The color development is stopped and the intensity of the color is measured.
Detection Method: Colorimetric
Conjugate: N/A

Usage Note: • 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.
Storage Instruction: The unopened kit should be stored at 2 - 8°C. After opening, please store refer to protocols.
Shipping: Gel pack with blue ice.

Background: Tissue transglutaminase (abbreviated as tTG or TG2) is a 78-kDa, calcium-dependent enzyme (EC 2.3.2.13) of the protein-glutamine γ-glutamyltransferases family (or simply transglutaminase family) . Like other transglutaminases, it crosslinks proteins between an ε-amino group of a lysine residue and a γ-carboxamide group of glutamine residue, creating an inter- or intramolecular bond that is highly resistant to proteolysis (protein degradation) . Aside from its crosslinking function, tTG catalyzes other types of reactions including deamidation, GTP-binding/hydrolyzing, and isopeptidase activities. Unlike other members of the transglutaminase family, tTG can be found both in the intracellular and the extracellular spaces of various types of tissues and is found in many different organs including the heart, the liver, and the small intestine. Intracellular tTG is abundant in the cytosol but smaller amounts can also be found in the nucleus and the mitochondria. Intracellular tTG is thought to play an important role in apoptosis. In the extracellular space, tTG binds to proteins of the extracellular matrix (ECM), binding particularly tightly to fibronectin. Extracellular tTG has been linked to cell adhesion, ECM stabilization, wound healing, receptor signaling, cellular proliferation, and cellular motility. tTG is particularly notable for being the autoantigen in celiac disease, a lifelong illness in which the consumption of dietary gluten causes a pathological immune response resulting in the inflammation of the small intestine and subsequent villous atrophy.
