Human Suppressor of tumorigenicity 14 protein (ST14) ELISA Kit

ST14 is an epithelial-derived, integral membrane serine protease. This protease forms a complex with the Kunitz-type serine protease inhibitor, HAI-1, and is found to be activated by sphingosine 1-phosphate. This protease has been shown to cleave and activate hepatocyte growth factor/scattering factor, and urokinase plasminogen activator, which suggest the function of this protease as an epithelial membrane activator for other proteases and latent growth factors. The expression of this protease has been associated with breast, colon, prostate, and ovarian tumors, which implicates its role in cancer invasion, and metastasis. ST14 lacks a signal sequence and is likely to be a membrane-associated serine protease.Expression was also observed in a colorectal adenocarcinoma cell line, but not in several other cell lines tested.

Human Suppressor of tumorigenicity 14 protein (ST14) ELISA Kit has high sensitivity and excellent specificity for detection of Human ST14. No significant cross-reactivity or interference between Human ST14 and analogues was observed.

This Human Suppressor of tumorigenicity 14 protein (ST14) ELISA Kit employs a two-site sandwich ELISA to quantitate ST14 in samples. An antibody specific for ST14 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyST14 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for ST14 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 ST14 bound in the initial step. The color development is stopped and the intensity of the color is measured.

• 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.
