Ib yam li ntawd, lub hom phiaj ntawm Permeabilization thaum txhaj tshuaj tiv thaiv yog dab tsi? cov tshuaj tiv thaiv siv rau kev tiv thaiv kab mob yog cov protein ntau molecules uas tsis tuaj yeem hla cov cell memebrane, yog li cov cell membrane yuav tsum tau muab tshem tawm kom tsis muaj antigens sab hauv ntawm tes. Lub voj voog ib feem ntawm cov tshuaj tiv thaiv kab mob uas txuas ncaj qha rau ib qho antigen.
Dhau li, lub hom phiaj ntawm kev kho cov cell yog dab tsi?
Kev kho ntawm cov ntaub so ntswg tau ua tiav rau ntau qhov laj thawj. Ib qho laj thawj yog tua cov ntaub so ntswg kom tiv thaiv kev puas tsuaj tom qab tuag (autolysis thiab putrefaction). Kev kho khaws cov khoom siv roj ntsha (cov ntaub so ntswg los yog hlwb ) kom ze rau nws lub xeev ntuj li sai tau nyob rau hauv cov txheej txheem ntawm kev npaj cov ntaub so ntswg rau kev kuaj.
Dab tsi yog saponin ua rau cov cell?
Cov organic solvents dissolve lipid los ntawm ntawm tes daim nyias nyias ua rau lawv nkag mus rau cov tshuaj tiv thaiv. Vim tias cov kuab tshuaj organic tseem coagulate cov protein, lawv ua tau yuav siv los txhim kho thiab permeabilize hlwb tib lub sijhawm. Saponin cuam tshuam nrog cov roj cholesterol membrane, xaiv tshem nws thiab tawm qhov hauv daim nyias nyias.

Cov kua muag sib xyaw nrog cov hnoos qeev nyob ntawd thiab koj lub qhov ntswg khiav. Tab sis cov ntshav ntxiv no ua rau cov kua ntau ntxiv
Peb yog vim li cas vim li cas lub cell faib?
Nov yog cov laj thawj vim li cas cov cell faib. Vim li cas 1: Mitosis thiab meiosis yog cov txheej txheem tseem ceeb. Vim li cas 2: Cell faib rau lub cev kev loj hlob thiab kev loj hlob. Yog vim li cas 3: Cov cell faib los kho peb lub cev. Kev faib tawm ntawm tes yog qhov tseem ceeb rau peb lub cev kev loj hlob thiab kev loj hlob
Vim li cas tus txha caj qaum thiab lub hlwb hu ua lub hauv nruab nrab lub paj hlwb?
Lub hauv paus paj hlwb muaj lub hlwb thiab tus txha caj qaum. Nws raug xa mus rau "lub hauv paus" vim tias nws ua ke cov ntaub ntawv los ntawm tag nrho lub cev thiab tswj kev ua haujlwm thoob plaws lub cev
Vim li cas peb yuav tsum zom peb cov zaub mov?
Kev zom zaub mov yog qhov tseem ceeb rau kev zom cov zaub mov rau hauv cov khoom noj, uas lub cev siv rau lub zog, kev loj hlob, thiab kho cell. Cov zaub mov thiab dej haus yuav tsum tau hloov mus rau hauv me me molecules ntawm cov as-ham ua ntej cov ntshav absorbs lawv thiab nqa mus rau cov hlwb thoob plaws hauv lub cev
