Anti-PSD-95 (K28/43) Recombinant Guinea Pig Chimeric mAb

Our guinea pig Anti-PSD 95 recombinant monoclonal antibody is a chimeric antibody derived from NeuroMab clone K28/43. It is KO validated, detects chicken, human, mouse, non-human primate, and rat PSD 95, and is purified by affinity chromatography. It works in WB, IHC, ICC, IP, ELISA.

Product Specifications

Background

PSD-95 is a member of the MAGUK (membrane associated guanylate kinase) family (which also includes PSD-93, SAP97 and SAP102) and functions as a scaffold protein that can cluster membrane receptors, ion channels, including NMDA receptor subunits, Kv1 potassium channels and Caspr2. The protein is encoded by DLG4, contains hallmark PDZ, SH3 and GuK domains and is found at post synaptic densities where it plays an important role in the formation and maintenance of synaptic junctions (Zhou and Blumberg, 2003) . Indeed, overexpression or depletion of DLG4 changes the ratio of excitatory to inhibitory synapses in hippocampal neurons. Antibodies against PSD95/DLG4 are frequently used in conjunction with pre-synaptic markers to localize synapses by microscopy

Notes

This recombinant antibody is a chimeric antibody created by replacing the mouse heavy and light constant regions of clone K28/43 with guinea pig IgG heavy and light constant regions. As such this antibody retains the same binding performance as the original clone K28/43 but can be detected using standard anti-guinea pig secondary antibodies allowing flexibility for multiplexing applications. This antibody is expressed recombinantly in mammalian cells and then affinity purified from the cell culture media.
