Background Information
PSD-95 (postsynaptic density protein 95) also known as SAP-90 (synapse-associated protein 90) is a protein that in humans is encoded by the DLG4 (disks large homolog 4) gene. PSD-95 is a scaffolding protein of the MAGUK protein family, and engages in several vital protein-protein interactions in the brain with its PDZ domains. It has been suggested that PSD-95 is composed of two supramodules, one of which is the PDZ1-2 tandem domain. It plays an important role in synaptic plasticity and the stabilization of synaptic changes during long-term potentiation. Observed MW of PSD95 is 90-95 kDa due to phosphorylation (PMID: 20682303).

FH Olga (Verified Customer) (10-03-2025) | You can surely dilute it more than 1:1000, as the signal was already saturated at 2.5 seconds of exposition. I find it better for mouse samples as it does not give non-specificity in non-brain tissues (comparing to 20665-1-AP PSD95 antibody) - all the mouse cells tested are of neuronal origin. The principal band size depends on protein marker used (see picture) - and can vary from 80 to 110 kDa.
