General description

PSD95 (postsynaptic density 95) represent a class of anchoring proteins which serve to localize various neuronal ion channels to post-synaptic densities. PSD95 and related proteins contain PDZ domains, which interact with NMDA receptors and voltage-gated K+ channels via a ET/SXV motif in the cytoplasmic carboxyl terminus of the receptor channels.


Recombinant protein corresponding to human PSD95.


Detect PSD95 using this Anti-PSD95 Antibody, clone K28/43 validated for use in IH, WB & IC.

Immunohistochemistry Analysis: 1:500 dilution from a previous lot detected PSD95 in rat cortex tissue.

Immunocytochemistry Analysis: A previous lot was used by an independent laboratory in IC. (Maeda, T., et al. (2005). Invest. Ophthalmol. Vis. Sci. 46(11):4320-4327.)
