Product Overview
Sandwich ELISA KitPLP2 encodes an integral membrane protein that localizes to the endoplasmic reticulum in colonic epithelial cells. The encoded protein can multimerize and may function as an ion channel. A polymorphism in the promoter of this gene may be linked to an increased risk of X-linked mental retardation. A pseudogene of this gene is found on chromosome 5. Oliva et al. (1993) cloned a cDNA encoding the A4 differentiation-dependent protein from a human colon cell line. Fisher et al. (1997) identified the …
Assay Principle
This assay employs a two-site sandwich ELISA to quantitate PLP2 in samples. An antibody specific for PLP2 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyPLP2 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for PLP2 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-e…

Stability & Storage
The stability of ELISA kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. The loss rate was determined by accelerated thermal degradation test. Keep the kit at 37°C for 4 and 7 days, and compare O.D.values of the kit kept at 37°C with that of at recommended temperature.

This is a sandwich ELISA kit. It employs a capture antibody pre-coated on the microplate surface and a biotin-conjugated detection antibody. After incubation with streptavidin-HRP and TMB substrate, a colorimetric signal proportional to analyte concentration is generated and measured at 450 nm.
The linear detection range of this kit is 0.156-10 ng/mL. Samples exceeding the upper limit must be diluted prior to testing. Samples below the lower limit may require concentration steps. Always verify that interpolated values fall within the linear portion of the standard curve.
This kit is validated for use with serum and plasma samples. Cell culture supernatants and tissue homogenates may also be tested after appropriate preparation. Avoid grossly hemolyzed, lipemic, or bacterially contaminated samples, as these may produce inaccurate results.
A microplate reader capable of measuring absorbance at 450 nm (with a 540–570 nm reference wavelength) is required. A plate washer is recommended for consistent washing steps. Calibrated micropipettes, incubator (37°C), and standard laboratory consumables are also needed.
