Ngesikhathi sokukhishwa, iphrotheni inamathele ku-BNP esebenzayo ngokomzimba (77th kuya ku-108th amino acids) kanye ne-n-terminal fragment NT-proBNP (1st kuya ku-76th amino acids).Lapho i-BNP, engama-amino acid angu-32 ubude, ikhishelwa egazini, ibophezela kuma-receptors ayo (NPRA kanye ne-NPRB) futhi ilawula umfutho wegazi ngokusebenzisa izindlela ezihlukahlukene.I-NT-proBNP, engama-amino acid angu-76 ubude, ayinawo umsebenzi webhayoloji, kodwa ngenxa yokuthi inohhafu wempilo ende kune-BNP, ifaneleka kakhulu njengenkomba yokuthola izifo ezihlukahlukene zenhliziyo.Ekuhlolweni komtholampilo kwezilwane ezifuywayo, ukugcwala kwegazi kwe-NT-proBNP ezinjeni kungaphezu kuka-900 pmol/L, futhi amakati angaphezulu kuka-270 pmol/L, futhi kunengozi enkulu yezifo ezihlobene nenhliziyo.Kodwa-ke, kufanele kuqashelwe ukuthi ngenxa yokuthi i-NT-proBNP ikhishwa yizinso, lapho isilwane sihlushwa izifo ezihlobene nezinso, ukuhlushwa kwe-NT-proBNP emzimbeni kuzophinde kwande futhi kubonakale amanga ekuhlolweni.
Lo mkhiqizo usebenzisa i-fluorescence immunochromatography ukuthola okuqukethwe kwe-fNT-proBNP ku-serum/plasma ngokobuningi.Isimiso esiyisisekelo: Kunemigqa engu-T no-C kulwelwesi lwefayibha ye-nitric acid ngokulandelana, futhi umugqa ongu-T umbozwe nge-antibody a eqaphela ngokukhethekile i-fNT-proBNP.Iphedi yenhlanganisela ifuthwa ngenye i-fluorescent nanomaterial ebhalwe ukuthi i-antibody b ekwazi ukuhlonza ngokuqondile i-FDT-probNP.Kusampula, i-FDT-probNP iqala ngokuhlangana ne-nanomaterial enelebuli ye-antibody b ukuze yakhe inkimbinkimbi, bese kuba i-chromatography ephezulu, inkimbinkimbi ihlangana ne-T-line antibody A ukuze kwakheke isakhiwo sesemishi.Lapho isasasa lomsebe wokukhanya, i-nanomaterial ikhipha amasiginali we-fluorescence.Amandla esignali ahlotshaniswa kahle nokugxila kwe-fNT-proBNP kusampula.
Selokhu yasungulwa, imboni yethu ibilokhu ithuthukisa imikhiqizo esezingeni lomhlaba ngokulandela isimiso
yekhwalithi kuqala.Imikhiqizo yethu izuze idumela elihle kakhulu embonini kanye nokwethenjwa okubalulekile phakathi kwamakhasimende amasha namadala..
