Human Eosinophil granule major basic protein (EMBP/MBP) ELISA Kit

Eosinophil granule major basic protein encoded by EMBP/MBP gene is the predominant constituent of the crystalline core of the eosinophil granule. High levels of the proform of this protein are also present in placenta and pregnancy serum, where it exists as a complex with several other proteins including pregnancy-associated plasma protein A (PAPPA), angiotensinogen (AGT), and C3dg. This protein may be involved in antiparasitic defense mechanisms as a cytotoxin and helminthotoxin, and in immune hypersensitivity reactions. The encoded protein contains a peptide that displays potent antimicrobial activity against Gram-positive bacteria, Gram-negative bacteria, and fungi. It is directly implicated in epithelial cell damage, exfoliation, and bronchospasm in allergic diseases. Alternatively spliced transcript variants encoding different isoforms have been found for EMBP/MBP.

Human Eosinophil granule major basic protein (EMBP/MBP) ELISA Kit has high sensitivity and excellent specificity for detection of Human PRG2. No significant cross-reactivity or interference between Human PRG2 and analogues was observed.

This Human Eosinophil granule major basic protein (EMBP/MBP) ELISA Kit employs a two-site sandwich ELISA to quantitate PRG2 in samples. An antibody specific for PRG2 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyPRG2 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for PRG2 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 PRG2 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.
