PAP Detection Service

Prostatic acid phosphatase (PAP) is a protein synthesized by the prostate gland and has been studied as a biomarker of prostate cancer for many years. Creative BioMart Biomarker provides customers with PAP testing services suitable for different sample types and helps customers accelerate relevant biomarker research. This test is only suitable for research use and not for clinical use.

PAP Testing
Analyte: PAP
Synonyms: prostatic acid phosphatase, prostatic specific acid phosphatase, PSAP
Sample Type: cell culture supernatant, plasma, serum, tissue homogenate and other biological fluids
Assay Platform: ELISA, CLIA
Biomarker Application Area: prostate cancer
* Perform three replicate tests on each sample, and include appropriate controls in each assay.

Assay Background

PAP is a glycoprotein synthesized by lysosomes of prostate epithelial cells with a molecular weight of 100kDa. The expression of PAP is related to testosterone and PAP has two forms, namely in the cellular form (cPAP) and the secretory form (sPAP). Two different forms of PAP have different biochemical properties, including hydrophobicity, glycosylation mode, isoelectric point, etc. cPAP has cellular protein tyrosine phosphatase activity and is highly expressed in prostate cells. Although sPAP is also expressed in prostate, most of it will be released into semen. The mRNA and protein expression levels of cPAP are reduced in prostate cancer tissues. Down-regulation of cPAP expression affects extracellular signal-regulated kinase (ERK)/mitogen-activated protein kinase (MAPK) signal transduction pathway, PI3K-AKT-AR pathway, and changes the RANKL/OPG system, in which the activation of ERK/MAPK signal transduction pathway is related to the development of prostate cancer. PAP can be used as a biomarker of prostate cancer, which is of significance for the monitoring and management of prostate cancer.
