Genes reported to be crucial for spermatogenesis are often exclusively expressed in the testis. The putative amino acid sequence encoded by the cDNA of the Pxt1 gene contains a conserved Asn-His-Leu (NHL)-motif at its C-terminal end, which is characteristic for peroxisomal proteins. Pxt1-EGFP fusion protein is co-localized with known peroxisomal marker proteins in transfected NIH3T3 cells. The peroxisomal targeting signal NHL is functional and responsible for the correct subcellular localization of the Pxt1-EGFP fusion protein. In male germ cells peroxisomes were reported only in spermatogonia. The Pxt1 gene is so far the first gene coding for a putative peroxisomal protein which is expressed in later steps of spermatogenesis, namely in pachytene spermatocytes.

Human Peroxisomal testis-specific protein 1 (PXT1) ELISA Kit employs a two-site sandwich ELISA to quantitate PXT1 in samples. An antibody specific for PXT1 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyPXT1 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for PXT1 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of PXT1 bound in the initial step. The color development is stopped and the intensity of the color is measured.
