Cov Ntawv Thov
1. Cov tswv cuab thiab Immunohistochemistry (IHC)
Kev siv thawj zaug: Dab yog cov feem ntau siv chromogenic substrate rau portoskas enzymes (tshwj xeeb yog horseradish peroxidase, hrp) hauv IHC staining.
Thaum oxidized los ntawm hrp nyob rau hauv hydrogen peroxide, dab ua cov ntaub ntawv insoluble daj xim av nag los ntawm lub xaib ntawm enzyme kev ua.
Qhov no tso cai rau kev pom ntawm antigens lossis cov protein hauv cov ntaub so ntswg hauv seem hauv lub tshuab tsom.
Feem ntau siv hauv kev kuaj mob pathologalisic los kuaj cov qog nqaij hlav culture, kis tus neeg mob, thiab lwm cov protein.
2. Electron tsom iav
Siv los ua cov yees duab-oxidation reagent mus rau cheeb tsam enzyme hauv chaw ua ultrastries.
Lub dab precumate yog hluav taws xob-tuab, muaj txiaj ntsig rau kev tsheb ciav hlau hauv kev xa khoom hluav taws xob electron (TEM).
3. Kev txheeb xyuas Chemiser
Ua raws li reagent rau ntes peroxidase kev ua si hauv biochemical cia siab.
Ua haujlwm hauv ntau cov enzymatic thiab immunoassay raws.
4. Tshuaj Synthesis
Qee zaus siv los ua lub tsev thaiv lossis nruab nrab hauv cov khoom siv hluav taws xob muaj txiaj ntsig uas muaj ntxhiab tsw qab.
Cov txiaj ntsig
1. High rhiab heev thiab muaj qhov tshwj xeeb
Tsim cov xim muaj zog thiab ruaj khov uas tau yooj yim pom.
Muab kev sib haum zoo heev rau cov ntaub so ntswg tom qab ntawm microscopy.
2. Insoluble thiab tas mus li staining
Dab cov tshuaj tiv thaiv cov khoom noj haus cawv thiab cov kuab tshuaj organic, ua rau nws tsim nyog rau kev npaj swb tas li.
Tuaj yeem tiv taus ntau cov puag ncig ntawm staining lossis tsom xam.
3. Sib txuam
Tau tshaj ntau yam kev nrhiav khoom thiab tshuaj tiv thaiv conjugates.
Ua haujlwm tau zoo hauv ntau cov cheem nrog lwm yam chromogens.
4. Tsawg keeb kwm pib
Thaum siv kom raug, dab tsim cov keeb kwm tsis muaj keeb kwm tsis muaj keeb kwm, txhim kho clarity thiab reproppibility.
Tag
3,3-dhawv dej (dab neeg) ( Nws muaj peev xwm los ua ib qho kev ua haujlwm tas mus li, hluav taws xob-xim xim dub ua rau nws tsis tseem ceeb hauv kev kuaj mob pathology, thiab ultrastration kev tshawb fawb. Kev ua kom zoo yog qhov tseem ceeb vim nws cov tshuaj lom thiab muaj peev xwm carcinogenic xwm.
