sida loo kala saaro lysosomes-ka sameynta peroxisomes centrifugation
Hordhac ku saabsan Lysosomes iyo Peroxisomes
Lysosomes iyo peroxisomes waa laba organelles unug oo kala duwan oo leh shaqooyin kala duwan oo door muhiim ah ka ciyaara dheef-shiid kiimikaadka unugyada iyo homeostasis-ka. Lysosomes waa organelles xuub ku xiran oo ay ka buuxaan ensaymo dheefshiid oo mas'uul ka ah burburinta walxaha qashinka unugyada, walxaha shisheeye, iyo jeermisyada. Peroxisomes, dhanka kale, waxay ku lug leeyihiin falcelinno dheef-shiid kiimikaad oo kala duwan, gaar ahaan kuwa la xiriira sunta iyo dheef-shiid kiimikaadka lipid. Si aan si gaar ah u baranno organelles-kan, hal hab oo caadi ahaan loo isticmaalo waa centrifugation. Maqaalkan, waxaan ku sahamin doonnaa sida centrifugation loogu isticmaali karo si guul leh looga sooco lysosomes-ka iyo peroxisomes-ka.
Mabaadi'da iyo Farsamooyinka Centrifugation-ka
Centrifugation waa farsamo awood badan oo loo isticmaalo in lagu kala saaro qaybaha kala duwan ee isku darka kala duwan iyadoo lagu saleynayo cabbirkooda, cufnaantooda, iyo qaabkooda. Waxay ka shaqeysaa mabaadi'da ceelasha, halkaas oo walxaha culus ay si dhakhso ah u degaan iyagoo saameyn ku leh xoogga centrifugal. Si loo kala saaro lysosomes-ka iyo peroxisomes-ka, waxaa la isticmaali karaa farsamooyin centrifugation oo kala duwan, sida centrifugation-ka kala duwan iyo centrifugation-ka cufnaanta,.
Kala-soocidda Kala-duwanaanshaha: Soo saarista Lysosomes iyo Peroxisomes
Kala-soocidda kala-soocidda waxay ku lug leedahay taxane tallaabooyin centrifugation ah oo xawaare iyo muddooyin kala duwan leh si loo kala saaro organelles iyadoo lagu saleynayo cufnaantooda. Waa kan sida loo isticmaali karo in lagu soo saaro lysosomes iyo peroxisomes:
Tallaabada 1: Is-dhexgalka
Tallaabada ugu horreysa waa in si tartiib ah loo kala furfuro unugyada oo la sii daayo waxa ku jira iyadoo la adeegsanayo farsamo isku-dhafan. Tan waxaa lagu gaari karaa iyadoo la isticmaalayo sonicating ama isticmaalka homogenizer gaar ah. Isku darka ka dhasha waxaa loogu yeeraa homogenate.
Tallaabada 2: Centrifugation-ka Xawaaraha Hoose
Dabadeed homogenate-ka waxaa lagu sameeyaa centrifugation xawaare hoose (qiyaastii 1,000-2,000 xg) muddo gaaban. Tallaabadani waxay ka caawisaa kala soocidda qashinka unugyada waaweyn iyo jajabka nukliyeerka inta kale ee organelles-ka ku jira homogenate-ka.
Tallaabada 3: Centrifugation-ka Xawaaraha Dhexe
Dusha sare ee laga helo tallaabada centrifugation-ka xawaaraha hoose waxaa lagu sameeyaa centrifugation xawaare dhexdhexaad ah (qiyaastii 10,000 xg) oo ay ku fadhiisiyaan organelles culus sida lysosomes iyo peroxisomes. Tallaabadani waxay keentaa pellet ka kooban organelles-kan.
Tallaabada 4: Dhaq oo dib u jooji
Kiniinka laga helay tallaabadii hore waxaa lagu dhaqaa xal ku habboon oo la keydiyey ka dibna dib loo hakiyo si loo helo jajab lysosome iyo peroxisome ah oo la safeeyey.
Santuuqaynta Cufnaanta ee Cufnaanta: Sifeynta Kala-soocidda
Centrifugation-ka cufnaanta waa farsamo centrifugation oo horumarsan oo u oggolaanaysa nadiifin dheeraad ah iyo sifeyn lysosomes iyo peroxisomes. Farsamadan, curfness gradient waxaa lagu sameeyaa iyadoo la isticmaalayo xal gradient-forming ah sida sucrose ama iodixanol. Waa kan sida loo isticmaali karo:
Tallaabada 1: Diyaarinta Cufnaanta Gradient
Dhexdhexaad cufnaanta, sida sucrose, ayaa lagu diyaariyaa tuubo centrifuge ah, oo leh cufnaan kala duwan oo ka bilaabma kor ilaa hoose ama hoose ilaa sare. Halabuurka iyo cufnaanta dhexdhexaadka ayaa si taxaddar leh loo doortaa, iyadoo la hubinayo inuu ka fudud yahay peroxisomes laakiin ka cufan yahay lysosomes.
Tallaabada 2: Lakabeynta Muunadda
Jajabka lysosome-ka iyo peroxisome-ka ee dib loo hakiyey ee laga helay centrifugation-ka kala duwan ayaa si taxaddar leh loogu dhejiyay dusha sare ee cufnaanta.
Tallaabada 3: Centrifugation
Tuubada waxaa markaa lagu sameeyaa centrifugation xawaare sare leh (ultracentrifugation) si loo kala saaro lysosomes iyo peroxisomes iyadoo lagu saleynayo cufnaanta ay leeyihiin. Inta lagu jiro centrifugation, organelles waxay dhex maraan bartamaha ilaa ay gaaraan meel cufnaanta ay ku jiraan ay la mid tahay cufnaanta dhexdhexaadka ku xeeran, iyagoo sameeya xarigyo kala duwan.
Falanqaynta iyo Codsiyada Dheeraadka ah
Ka dib marka si guul leh loo kala saaro, jajabyada lysosome iyo peroxisome ee la helay waxaa si dheeraad ah loo falanqeyn karaa iyadoo la adeegsanayo farsamooyin kala duwan si loo qiimeeyo daahirnimadooda, cabbirkooda, halabuurka, iyo sifooyinka shaqada. Farsamooyinka sida mikroskoobka elektaroonigga ah, immunocytochemistry, iyo tijaabooyinka dhaqdhaqaaqa ensaymka ayaa bixin kara aragtiyo qiimo leh oo ku saabsan jajabyada go'doonsan, iyagoo xaqiijinaya aqoonsigooda iyo daahirnimadooda.
Marka laga reebo ujeeddooyinka cilmi-baarista, awoodda lagu kala saaro lysosomes iyo peroxisomes iyada oo loo marayo centrifugation waxay leedahay codsiyo ku saabsan baaritaanka caafimaadka, horumarinta daawada, iyo faragelinta daaweynta. Iyagoo si fiican u fahmaya shaqooyinka organelles-kan, saynisyahannadu waxay sahamin karaan xeelado cusub oo daaweyn ah oo lagu beegsanayo cilladaha lysosomal ama peroxisomal, sida cudurrada kaydinta lysosomal ama cilladaha bayogenesis peroxisome.
Gunaanadkii, kala soocidda lysosomes-ka iyo peroxisomes-ka iyadoo la adeegsanayo farsamooyinka centrifugation-ka, sida centrifugation-ka kala duwan iyo centrifugation-ka cufnaanta, waa hab lagama maarmaan u ah cilmi-baarista bayoolajiga unugyada. Farsamooyinkani waxay awood u siinayaan saynisyahannada inay helaan jajabyo la safeeyey oo ah lysosomes iyo peroxisomes, iyagoo ka caawinaya fahamka doorarkooda shaqsiyeed, waddooyinka dheef-shiid kiimikaadka, iyo faragelinta daaweynta ee suurtagalka ah ee cudurada la xiriira.
