UKUSETYENZISWA OKUHLOSIWEYO
Diagnostic KityeProstate Specific Antigen (i-fluorescence immunochromatographic assay) yi-fluorescence immunochromatographic
Uvavanyo lokufumanisa ubungakanani beProstate Specific Antigen (PSA) kwiserum yabantu okanye iplasma, esetyenziswa ikakhulu ukufumanisa isifo sedlala lengqula. Olu vavanyo lwenzelwe
ukusetyenziswa kwezempilo kuphela.
USHWANKATHELO
I-PSA (i-Prostate Specific Antigen) idityanisiwe kwaye ikhutshelwe ngeeseli ze-prostate epithelial kwi-semen kwaye yenye yezona nxalenye eziphambili ze-plasma ye-seminal.Iqulethe iintsalela ze-amino acid ezingama-237 kunye nobunzima bayo bemolekyuli malunga ne-34kD.Inomsebenzi we-serine protease wekhonkco elinye. glycoprotein, bathathe inxaxheba kwinkqubo ye-semen liquefaction. I-PSA egazini sisimbuku sePSA apho kunye nePSA edibeneyo. amanqanaba eplasma yegazi, kwi-4 ng/mL yexabiso elibalulekileyo, i-PSA kumhlaza wesibeleko Ⅰ ~ Ⅳ ixesha lovakalelo lwe-63%, 71%, 81% kunye ne-88% ngokulandelanayo.
