Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Prostate Specific Antigen antibody [8301] (AB403)

Human normal prostate. Staining is localised as cytoplasmic and secreted. Left panel : with primary antibody at 1 ug/ml. Right panel : isotype control. Sections were stained using an automated system, at room temperature : sections were rehydrated and antigen retrieved with buffers (citrate pH 6.1) in a PT Link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min and detected for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that for manual staining we recommend to optimize the primary antibody concentration and incubation time (overnight incubation), and amplification may be required.

Specificity

Human prostate-specific antigen - 100% PSA/alpha-1-ACT-complex - 59%Kallikrein - <0.04% PAP - <0.04% Cross-reactivity values have been calculated on weight/weight basis using 125-I-labelled human human prostate-specific antigen in assay. They can vary because of the presence of antigen or related impurities in protein preparations used for cross reactivity assays.Affinity constant: 1x10<sup>11</sup> l/mol human prostate-specific antigen.

Prostate Specific Antigen (PSA) also known as kallikrein-related peptidase 3 (KLK3) is a serine protease with a mass of approximately 28.4 kDa. PSA is primarily expressed in the epithelial cells of the prostate gland. This glycoprotein is an important component in the seminal fluid where it performs its proteolytic activity that liquefies semen facilitating sperm motility.

Biological function summary

PSA functions by cleaving the gel-forming proteins present in seminal coagulum. It does not operate as part of a larger protein complex. PSA also interacts with substrates like fibronectin and semenogelin which play roles in seminal coagulation and liquefaction. The expression of PSA in prostate tissue has made it a valuable biomarker for prostate function and pathological conditions.

Pathways

PSA is involved in the kallikrein-kinin system which influences inflammation and blood pressure regulation. PSA is not directly a part of key metabolic or signaling pathways but it is co-expressed with key proteins like androgen receptor (AR) which modulates PSA's expression. The interplay between androgens and PSA highlights its role in hormone regulation within the male reproductive system.

PSA levels serve as an indicator for prostate cancer and benign prostatic hyperplasia (BPH). Elevated PSA levels often correlate with prostate cancer although other prostate conditions such as prostatitis can also increase PSA without cancer. Proteins like PCA3 and the AR are also connected in the context of prostate cancer providing a broader understanding of PSA's role in these diseases.
