LS-F33296 is a 96-well enzyme-linked immunosorbent assay (ELISA) for the Quantitative detection of Human DLG4 / PSD95 in samples of Plasma, Serum and Tissue Homogenates. It is based upon a Sandwich assay principle and can be used to detect levels of DLG4 / PSD95 as low as 0.188 nanograms per millilter.

Quality Assurance
Due to their limited shelf life, LSBio ELISA kits are not typically stocked as finished goods. Upon receipt of an order each kit is assembled and tested to ensure that it meets specifications before shipping. Minor changes may occur to the Range, Sensitivity, and Precision. In the event of a significant change the order would be confirmed with the customer before shipping ELISA kit lot numbers reflect the date of final assembly and testing for each specific kit rather than a bulk manufactured lot. All kits are tested to confirm that they fall within their defined Inter- and Intra- assay coefficient of variation.

Background
This kit was based on sandwich enzyme-linked immune-sorbent assay technology. Anti- DLG4antibody was pre-coated onto 96-well plates. And the biotin conjugated anti- DLG4 antibody was used as detection antibodies. The standards, test samples and biotin conjugated detection antibody were added to the wells subsequently, and wash with wash buffer. HRP- Streptavidin was added and unbound conjugates were washed away with wash buffer. TMB substrates were used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the DLG4 amount of sample captured in plate. Read the O.D. absorbance at 450nm in a microplate reader, and then the concentration of DLG4 can be calculated.
Restrictions
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. P78352NM_001365NP_001356.1
