Human Mucin-4 (MUC4) ELISA Kit

The major constituents of mucus, the viscous secretion that covers epithelial surfaces such as those in the trachea, colon, and cervix, are highly glycosylated proteins called mucins. These glycoproteins play important roles in the protection of the epithelial cells and have been implicated in epithelial renewal and differentiation. MUC4 encodes an integral membrane glycoprotein found on the cell surface, although secreted isoforms may exist. At least two dozen transcript variants of MUC4 have been found, although for many of them the full-length transcript has not been determined or they are found only in tumor tissues. MUC4 contains a region in the coding sequence which has a variable number (>100) of 48 nt tandem repeats.

Human Mucin-4 (MUC4) ELISA Kit has high sensitivity and excellent specificity for detection of Human MUC4. No significant cross-reactivity or interference between Human MUC4 and analogues was observed.

This Human Mucin-4 (MUC4) ELISA Kit employs a two-site sandwich ELISA to quantitate MUC4 in samples. An antibody specific for MUC4 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyMUC4 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for MUC4 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 MUC4 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.
