Reticular fibers, reticular fibers los yog reticulin yog ib hom fiber ntau hauv cov ntaub so ntswg sib txuas ua los ntawm hom III collagen secreted los ntawm cov hlwb reticular … xws li daim siab, pob txha pob txha, thiab cov ntaub so ntswg thiab cov kabmob ntawm cov lymphatic system.
Reticulin yog dab tsi?
Reticulin yog thib plaub ntawm cov protein hauv cov ntaub so ntswg sib txuas… Thaum kawg, ntau cov pob ntawm fibers tau sib sau ua ke loj ntawm cov fibers thiab ncig los ntawm epimysium, txheej txheej ntawm connective ntaub so ntswg. Cov qauv no yog cov leeg nqaij hauv cov nqaij (Daim duab 12.4).
Reticulin pom nyob qhov twg?
Reticulin fibers txhawb lub cev thiab muaj nyob rau hauv lub siab, spleen thiab raum.
YPuas yog reticulin yog protein?
Stromal proteins, tseem hu ua cov ntaub so ntswg sib txuas, feem ntau suav nrog collagen, elastin, thiab reticulin. Cov no tuaj yeem pom hauv daim tawv nqaij, pob txha, leeg, pob txha mos, thiab cov leeg nws tus kheej.
Yuav siv txoj kev twg los ua kom pom cov reticulin fibers?
Tus Gordon thiab Sweet's silver staining method yog siv los ua kom pom cov reticular (retic) fibers.

Txhais li cas rau cov protein kom denatured thiab yuav ua li cas lawv thiaj ua tau zoo?
Denaturation, hauv biology, txheej txheem hloov kho cov qauv molecular ntawm cov protein… Cov proteins uas tau hloov pauv muaj qhov xoob, ntau dua random qauv; feem ntau yog insoluble. Denaturation tuaj yeem coj los ntawm ntau txoj hauv kev-xws li, los ntawm cua sov, los ntawm kev kho nrog alkali, kua qaub, urea, los yog detergents, thiab los ntawm kev tshee tshee .

Reticulin yog thib plaub ntawm cov protein hauv cov ntaub so ntswg sib txuas… Thaum kawg, ntau cov pob ntawm fibers tau sib sau ua ke loj ntawm cov fibers thiab ncig los ntawm epimysium, txheej txheej ntawm connective ntaub so ntswg.
Nyob rau hauv txoj kev staining rau reticulin?
