anti-Plakophilin 2 guinea pig polyclonal, serum

Plakophilin 2 is a desmosomal plaque protein in simple and glandular epithelia, basal layer of stratified epithelia and in some nonepithelial tissues, e.g. myocard; in some cells devoid of desmosomes, PP2 is enriched in the karyoplasm.

Tested species reactivity bovine, human, mouse, pig, rat (negative with amphibia and fish)


Tested applications Tested dilutions
Immunocytochemistry (ICC)/ Immunofluorescence (IF) assay dependent
Immunohistochemistry (IHC) - frozen 1:100 (preincubated for 5 min with 0.2% Triton X-100 prior to antibody application recommended; longer incubation could result in a loss of nuclear PP2-staining; fixation with 2% formaldehyde to prevent wash-out of soluble forms)

Western Blot (WB) assay dependent



PP2 antiserum stains specifically desmosomal plaques present in simple and glandular epithelia, the basal layer of certain stratified epithelia, all layers of some stratified epithelia, and desmosome-possessing nonepithelial cells such as myocardium, Purkinje fibers, and dendritic reticulum of lymph node follicles. In all these cells, including a variety of cell types devoid of desmosomes, plakophilin 2 is highly enriched in the karyoplasm.
