The expression profile observed is consistent with what has been described in the literature (PMID: 20596736, 12855640, 26055798).
Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Psoriasin antibody [EPR23482-38] (ab275026)

Immunohistochemical analysis of paraffin-embedded human skin tissue labeling Psoriasin with ab275026 at 1/500 dilution followed by ready to use Rabbit specific IHC polymer detection kit HRP/DAB (ab209101). Positive staining on human skin (PMID: 18223693). The section was incubated with ab275026 for 30 mins at room temperature. The immunostaining was performed on a Leica Biosystems BOND^® RX instrument. Counterstained with Hematoxylin.

Secondary antibody only control: Secondary antibody is ready to use Rabbit specific IHC polymer detection kit HRP/DAB (ab209101).

Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution2) for 20 mins.
Immunocytochemistry - Anti-Psoriasin antibody [EPR23482-38] (ab275026)

Immunofluorescent analysis of 4% Paraformaldehyde-fixed, 0.1% Triton X-100 permeabilized MDA-MB-468 cells labelling Psoriasin with ab275026 at 1/250 (2.132 µg/ml) dilution, followed by ab150077 Goat Anti-Rabbit IgG H&L (Alexa Fluor^® 488) antibody at 1/1000 dilution (Green). Confocal image showing cytoplasmic staining in MDA-MB-468 cells.

Negative control: MDA-MB-231 (PMID: 15994944).

ab195889 Anti-alpha Tubulin mouse monoclonal antibody - Microtubule Marker (Alexa Fluor^® 594) was used to counterstain tubulin at 1/200 dilution (Red). The nuclear counterstain was DAPI (Blue).

Flow Cytometry - Anti-Psoriasin antibody [EPR23482-38] (ab275026)

Flow cytometric analysis of 4% paraformaldehyde fixed 90% methanol permeabilized MDA-MB-468 (Human breast adenocarcinoma epithelial cell) cells labelling Psoriasin with ab275026 at 1/500 dilution (0.1µg) (Red) compared with a Rabbit monoclonal IgG (ab172730) (Black) isotype control and an unlabelled control (cells without incubation with primary antibody and secondary antibody) (Blue).

A Goat anti rabbit IgG (Alexa Fluor^® 488, ab150077) at 1/2000 dilution was used as the secondary antibody.
Immunoprecipitation - Anti-Psoriasin antibody [EPR23482-38] (ab275026)

Psoriasin was immunoprecipitated from 0.35 mg MDA-MB-468 (human breast adenocarcinoma epithelial cell), whole cell lysate with ab275026 at 1/30 dilution (2µg in 0.35mg lysates). Western blot was performed on the immunoprecipitate using ab275026 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP)(ab131366) was used at 1/5000 dilution.
