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 degree 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.
* Allow all reagents to warm to room temperature for at least 30 minutes before opening.

Description: This Human Kallistatin (SERPINA4) ELISA Kit employs a two-site sandwich ELISA to quantitate SERPINA4 in samples. An antibody specific for SERPINA4 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any SERPINA4 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for SERPINA4 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 SERPINA4 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Background: Kallistatin is a serine proteinase inhibitor (serpin) and a heparin-binding protein. It is localized in vascular smooth muscle cells and endothelial cells of blood vessels, suggesting that it may be involved in the regulation of vascular function.The 1,284-bp cDNA encodes 427 amino acid residues, including a 26-residue signal peptide and a 401-residue mature peptide. The translated amino acid sequence of kallistatin matches the protein sequence and shares 44 to 46% sequence identity with human alpha-1-antichymotrypsin (AACT), alpha-1-antitrypsin (PI), corticosteroid-binding globulin (CBG), thyroxine-binding globulin of serum (TBG), and protein C inhibitor (PCI). All of these except TBG, which is encoded by the X chromosome, are encoded by genes on chromosome 14.

Uniprot Description
SERPINA4: Inhibits human amidolytic and kininogenase activities of tissue kallikrein. Inhibition is achieved by formation of an equimolar, heat- and SDS-stable complex between the inhibitor and the enzyme, and generation of a small C-terminal fragment of the inhibitor due to cleavage at the reactive site by tissue kallikrein. Belongs to the serpin family.

Product Notes
The Human KST serpina4 (Catalog #AAA9714369) is an ELISA Kit and is intended for research purposes only. The product is available for immediate purchase. The AAA9714369 ELISA Kit recognizes Human KST. It is sometimes possible for the material contained within the vial of "Kallistatin (SERPINA4), ELISA Kit" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
