UKUSETSHENZISWA OKUHLOSIWE
Ikhithi YokuxilongaI-Prostate Specific Antigen (ukuhlolwa kwe-fluorescence immunochromatographic) iyi-fluorescence immunochromatographic
ukuhlolwa kokuthola inani le-Prostate Specific Antigen (PSA) ku-serum noma ku-plasma yomuntu, esetshenziswa kakhulu ekuxilongeni okusizayo kwesifo se-prostate. Wonke amasampula abonisa ukuthi akhona kumele aqinisekiswe ngezinye izindlela. Lokhuukuhlolwakuhloswe ngakho
ukusetshenziswa kochwepheshe bezempilo kuphela.
ISIFINYEZO
I-PSA（Prostate Specific Antigen） ikhiqizwa futhi ikhishwe ngamaseli e-prostate epithelial ibe yi-semen futhi ingenye yezingxenye eziyinhloko ze-plasma yesidoda. Iqukethe ama-amino acid residues angu-237 futhi isisindo sayo sama-molecule singama-34kD. Inomsebenzi we-serine protease we-single chain glycoprotein, ihlanganyela enkambisweni yoketshezi lwesidoda. I-PSA egazini iyisamba se-PSA kanye ne-PSA ehlanganisiwe. Amazinga e-plasma yegazi, ku-4 ng/mL ngenani elibalulekile, i-PSA kumdlavuza we-prostate Ⅰ ~ Ⅳ isikhathi sokuzwela okungu-63%, 71%, 81% kanye no-88% ngokulandelana.
