Chromogenic TAL Assay (Chromogenic Endotoxin Test Assay)
TAL reagent yog lyophilized amebocyte lysate uas tau muab rho tawm los ntawm cov ntshav xiav ntawm Limulus polyphemus lossis Tachypleus tridentatus.
Endotoxins yog amphiphilic lipopolysaccharides (LPS) nyob rau hauv lub cell membrane ntawm cov kab mob gram-tsis zoo.Cov khoom lag luam parenteral kis nrog pyrogens suav nrog LPS tuaj yeem ua rau muaj kev txhim kho kub taub hau, ua rau cov lus teb inflammatory, poob siab, lub cev tsis ua haujlwm thiab kev tuag ntawm tib neeg.Yog li ntawd, cov teb chaws thoob plaws ntiaj teb tau tsim cov kev cai, xav kom cov khoom lag luam uas thov kom tsis muaj menyuam thiab tsis yog pyrogenic yuav tsum tau sim ua ntej tso tawm.Gel-clot TAL assay yog thawj zaug tsim rau cov kab mob endotoxins kuaj (piv txwv li BET).Txawm li cas los xij, lwm txoj hauv kev siab dua ntawm TAL kev soj ntsuam tau tshwm sim.Thiab cov txheej txheem no yuav tsis tsuas yog kuaj pom tab sis kuj suav tias muaj cov endotoxins hauv cov qauv.
Sib nrug los ntawm cov txheej txheem gel-clot, cov tswv yim rau BET kuj muaj cov txheej txheem turbidimetric thiab cov txheej txheem chromogenic.
Bioendo, mob siab rau kev kuaj pom endotoxin, yog cov kws tshaj lij tsim khoom tsim kom muaj kev kuaj chromogenic TAL.BioendoTMEC Endotoxin Test Kit (End-point Chromogenic Assay) muab kev ntsuas ceev rau endotoxin kom muaj nuj nqis.Peb kuj muab BioendoTMKC Endotoxin Test Kit (Kinetic Chromogenic Assay) thiab incubation microplate nyeem ELx808IULALXH, uas tuaj yeem ua kom ntseeg tau thiab ua haujlwm ntawm koj qhov kev sim.
