Anti-PSD-93 Antibody

Postsynaptic density protein 93 (PSD-93, also known as DLG2 or Chapsyn-110) is a MAGUK-family scaffolding protein critical for organizing NMDA receptor clusters and associated signaling complexes at excitatory synapses. This rabbit polyclonal reagent from Antibodies.com recognizes PSD-93 across Human, Mouse, and Rat samples, supporting studies of glutamatergic synapse maturation, receptor trafficking, and neurological disease models involving DLG2 dysfunction.

Supplied as 100 µl of liquid at 1 mg/ml in phosphate buffered saline (PBS) containing 0.05% sodium azide at approximately pH 7.2, the unconjugated antibody is validated for Western blot and immunocytochemistry workflows. Researchers commonly use it to probe synaptic protein expression in rodent brain lysates, primary neuron cultures, and fixed tissue sections where postsynaptic density composition is being characterized. Aliquot upon arrival, refrigerate short term, and freeze at -20 degrees C in working volumes to limit freeze-thaw cycles and preserve binding activity. Because sodium azide is included as a microbial preservative, the reagent is for research use only and is not recommended for live-cell imaging or diagnostic assays sensitive to azide.
