Chiyambi cha Centrifugation ndi Ntchito Zake

Kugawa zinthu pogwiritsa ntchito centrifugation ndi njira yomwe imagwiritsidwa ntchito kwambiri m'magawo a sayansi ndi mafakitale pogawa zinthu zosiyanasiyana zosakaniza kutengera kuchuluka kwake. Mwa kusinthasintha mofulumira chitsanzo pa liwiro lalikulu, kugawa zinthu pogwiritsa ntchito centrifugation kumagwiritsa ntchito mfundo za mphamvu yokoka ndi mphamvu yapakati kuti zilekanitse zosakaniza m'zigawo zosiyana. Kuyambira kuyeretsa zitsanzo zamoyo mpaka kulekanitsa zinthu zosiyanasiyana zamafakitale, kugawa zinthu pogwiritsa ntchito centrifugation kwakhala chida chofunikira kwambiri m'magawo ambiri.

Kulekanitsa Zosakaniza Zofanana Pogwiritsa Ntchito Centrifugation

Zosakaniza zofanana, momwe zigawozo zimagawika mofanana, zimafuna njira zapadera zoyezera kuti zilekanitse. Njira imodzi yomwe imagwiritsidwa ntchito kwambiri ndi differential centrifugation, yomwe imagwiritsa ntchito njira zingapo zoyezera pa liwiro losiyanasiyana kuti ilekanitse tinthu kutengera kukula ndi kuchuluka kwake. Mwa kuwonjezera liwiro pang'onopang'ono, tinthu tating'ono timayamba kutayikira, ndikusiya tinthu tating'onoting'ono pamwamba. Njira imeneyi nthawi zambiri imagwiritsidwa ntchito pofufuza za biochemical kuti ilekanitse organelles kuchokera ku maselo kapena zigawo za maselo zosiyana.

Kumbali inayi, kusinthasintha kwa kachulukidwe ka madzi kumalekanitsa tinthu kutengera kuchulukana kwa madzi komwe kumayandama. Mwa kupanga kuchuluka kwa madzi pogwiritsa ntchito njira yolemetsa (monga sucrose) pansi pa tinthu topepuka, chitsanzocho chimayikidwa pamwamba pake. Tinthu tikakhala pakati, timadutsa mu kachulukidwe ka madzi mpaka titafika pamlingo woyenera malinga ndi kuchuluka kwawo. Njira imeneyi imalola kulekanitsa ma nucleic acid, mapuloteni, ndi zinthu zina zomwe zili mu zitsanzo zamoyo.

Njira Zogwiritsira Ntchito Centrifugation pa Zosakaniza Zosiyanasiyana

Zosakaniza zosiyanasiyana, zomwe zimakhala ndi zigawo zosiyana, zimatha kulekanitsidwa pogwiritsa ntchito njira zosiyanasiyana zoyezera. Kuyezera kwa sedimentation kumagwiritsidwa ntchito kwambiri pazosakaniza zotere. Monga momwe dzinalo likusonyezera, njira imeneyi imaphatikizapo kuyika tinthu tating'onoting'ono kutengera kuchuluka kwake. Tinthu tolemera timakhazikika pansi pa chubu cha centrifuge pomwe zinthu zopepuka zimatsalira mu supernatant.

Nthawi zina, zosakaniza zosiyanasiyana zimatha kulekanitsidwa pogwiritsa ntchito njira yotchedwa filtration centrifugation kapena screen centrifugation. Njirayi imagwiritsa ntchito fyuluta, monga sefa, kuti isunge tinthu tating'onoting'ono tomwe timalowamo pamene timalola tinthu tating'onoting'ono kudutsa. Pogwiritsa ntchito kusiyana kwa kukula kwa tinthu, filtration centrifugation imalekanitsa bwino zinthu kutengera kukula kwake. Njirayi yagwiritsidwa ntchito pochiza madzi otayira, kupanga mankhwala, ndi mafakitale ena osiyanasiyana.

Kukonza Zinthu M'mafakitale: Kuyambira Mankhwala Kupita Kukakonza Chakudya

Kutsegula mpweya m'thupi (centrifugation) kumagwira ntchito yofunika kwambiri m'mafakitale osiyanasiyana, kuphatikizapo mankhwala, sayansi ya zamoyo, ndi kukonza chakudya. Mu gawo la mankhwala, kutsegula mpweya m'thupi (centrifugation) kumagwiritsidwa ntchito kwambiri pofufuza mankhwala, kupanga katemera, komanso kulekanitsa zosakaniza zogwira ntchito. Kumathandiza kuyeretsa mankhwala ndikuchotsa zinyalala, kuonetsetsa kuti mankhwala otetezeka komanso ogwira mtima apangidwa.

Mu gawo la sayansi ya zamoyo, kugawa maselo m'maselo n'kofunika kwambiri pa kugawa DNA, kuyeretsa mapuloteni, ndi kugwiritsa ntchito maselo. Mwa kulekanitsa zigawo zosiyanasiyana za maselo, kugawa maselo m'maselo kumalola ofufuza kuphunzira ndi kusanthula mamolekyulu enaake, kuthandiza m'madera monga kafukufuku wa majini ndi chitukuko cha mankhwala.

Mu makampani opanga chakudya, centrifugation imagwiritsidwa ntchito poyeretsa, kuyeretsa, ndi kuyika madzi m'thupi. Imagwiritsidwa ntchito kwambiri popanga madzi a zipatso, mafuta odyedwa, mkaka, ndi zakumwa zoledzeretsa. Centrifuge imathandiza kuchotsa tinthu tosafunikira, kulekanitsa madzi ndi zinthu zolimba, ndikuwonjezera ubwino wonse wa chinthu chomaliza.

Kupita Patsogolo mu Ukadaulo wa Centrifugation

Kwa zaka zambiri, ukadaulo wa centrifugation wapita patsogolo kwambiri, zomwe zapangitsa kuti pakhale zotsatira zogwira mtima komanso zolondola zolekanitsa. Kuyambitsidwa kwa centrifuge yothamanga kwambiri komanso yolimba kwasintha kwambiri gawoli, zomwe zathandiza ofufuza kukonza zitsanzo zambiri munthawi yochepa.

Kuphatikiza apo, kupita patsogolo kwa kapangidwe ka centrifuge kwapangitsa kuti pakhale njira zapadera zogwiritsira ntchito zinazake. Mwachitsanzo, ma microcentrifuge amapangidwira zitsanzo zazing'ono, pomwe ma ultracentrifuge amatha kufika pa liwiro lalikulu kwambiri, zomwe zimathandiza kulekanitsa zigawo za subcellular ndi ma macromolecules.

Kutsegula magetsi pogwiritsa ntchito makina oyendera magetsi kwapindulanso ndi kupita patsogolo kwa makina oyendetsera magetsi ndi owongolera, zomwe zathandiza kuti pakhale kulondola komanso kubwerezabwereza. Makina oyendera magetsi amakono ali ndi mawonekedwe osavuta kugwiritsa ntchito, makonda okonzedwa, komanso zinthu zotetezeka, zomwe zimapangitsa kuti ogwiritsa ntchito osiyanasiyana azitha kuwagwiritsa ntchito mosavuta m'mafakitale osiyanasiyana.

Pomaliza, centrifugation ndi njira yosinthasintha yolekanitsira zosakaniza kutengera kuchulukana kwawo. Kuyambira kulekanitsa zosakaniza zofanana pogwiritsa ntchito differential and density gradient centrifugation mpaka kulekanitsa zosakaniza zosiyanasiyana pogwiritsa ntchito sedimentation ndi sefa centrifugation, njira iyi yagwiritsidwa ntchito kwambiri m'magawo asayansi ndi mafakitale. Ndi kupita patsogolo kwina mu kapangidwe ka centrifuge ndi ukadaulo, tsogolo la centrifugation lili ndi kuthekera kwakukulu kowonjezera luso lolekanitsa ndikuwongolera zokolola.
