DLG4 ELISA Kit (Mouse)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Discs, Large Homolog 4 (DLG4) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Discs, Large Homolog 4 (DLG4) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

Discs large homolog 4; discs, large homolog 4; disks large homolog 4; Dlgh; Dlgh4; postsynaptic density protein 95; PSD; PSD-; PSD95; PSD-95; PSD-95 alpha 2b; PSD-95 beta; SA; SAP90; SAP-90; SAP90A; synapse-associated protein 90.

Interacts with the cytoplasmic tail of NMDA receptor subunits and shaker-type potassium channels. Required for synaptic plasticity associated with NMDA receptor signaling. Overexpression or depletion of DLG4 changes the ratio of excitatory to inhibitory synapses in hippocampal neurons. May reduce the amplitude of ASIC3 acid-evoked currents by retaining the channel intracellularly. May regulate the intracellular trafficking of ADR1B. Also regulates AMPA-type glutamate receptor (AMPAR) immobilization at postsynaptic density keeping the channels in an activated state in the presence of glutamate and preventing synaptic depression (Probable) .

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 Discs, Large Homolog 4 (DLG4) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Discs, Large Homolog 4 (DLG4) . 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 Discs, Large Homolog 4 (DLG4), 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 Discs, Large Homolog 4 (DLG4) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
