SLIT1 ELISA Kit (Human)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Slit Homolog 1 (Slit1) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Slit Homolog 1 (Slit1) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

MEGF4; multiple EGF-like domains protein 4; multiple epidermal growth factor-like domains protein 4; SLIL1; slit homolog 1; slit homolog 1 protein; SLIT-1; SLIT3.

Thought to act as molecular guidance cue in cellular migration, and function appears to be mediated by interaction with roundabout homolog receptors. During neural development involved in axonal navigation at the ventral midline of the neural tube and projection of axons to different regions (By similarity) . SLIT1 and SLIT2 together seem to be essential for midline guidance in the forebrain by acting as repulsive signal preventing inappropriate midline crossing by axons projecting from the olfactory bulb.

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Slit Homolog 1 (Slit1) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Slit Homolog 1 (Slit1) . Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Slit Homolog 1 (Slit1), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm +/- 10nm. The concentration of Slit Homolog 1 (Slit1) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
