Invitrogen™ Mouse MCPT-1 (mMCP-1) Uncoated ELISA Kit with Plates

Description

The Mouse MCPT-1 (mMCP-1) Uncoated ELISA Kit contains pre-matched antibody pairs, plates and reagents for performing quantitative enzyme linked immunosorbent assays (ELISA) to detect and quantify protein levels of mouse MCPT-1. Wash Buffer and Stop Solution are needed to complete the ELISA reaction and are sold separately. Principle of the method ELISAs are designed to measure the amount of the target bound between a matched antibody pair. A target-specific antibody is coated to the bottom of the wells of a microplate, which is an overnight process. Samples, standards, or controls are then added into these wells and bind to the immobilized (capture) antibody. A sandwich is formed by the addition of the second (detector) antibody, a substrate solution is added that reacts with the enzyme-antibody-target complex to produce measurable signal. The intensity of this signal is directly proportional to the concentration of target present in the original specimen.

MCPT-1 is the only chymase expressed by intestinal mucosal mast cells, which are found in the intestinal epithelium. Although it is expressed constitutively and is detectable in the sera of normal mice, parasites in the gut cause systemic levels to increase dramatically within two days and peak at two weeks following infection. It plays an important role in host defense against intestinal parasites, as mice deficient in MCPT-1 display delayed response upon infection. Elevated MCPT-1 levels are also observed during intestinal allergic hypersensitivity reactions. The mechanism of its action is not fully understood, although it is believed to increase intestinal permeability similarly to rMCPT-II, possibly by cleaving the proteins at tight junctions between cells.
