Me pēhea te wehewehe a te centrifugation rerekē i ngā whekau
Te Whakapūtanga Rerekētanga: Te Wetewete i ngā Mea Ngaro o ngā Organelles
Kupu Whakataki
He tikanga kaha te centrifugation rerekētanga e whakamahia ana i roto i te rangahau koiora hei wehewehe i ngā wāhanga pūtau i runga i tō rātou rahi me te mātotoru. He mahi nui tāna ki te whakamārama i ngā mahi me ngā taunekeneke o ngā momo okana i roto i ngā pūtau. Mā te tuku i ngā mea ōrite ki roto i ngā pūtau ki tētahi raupapa o ngā mahi centrifugation raupapa i ngā tere rerekē, ka taea e ngā kaipūtaiao te wehewehe me te wehe i ngā okana, ka whakatakoto huarahi mō te tātaritanga hohonu. I roto i tēnei tuhinga, ka tūhuratia e mātou ngā mātāpono, ngā tikanga, me ngā tono o te centrifugation rerekētanga, me te whakamārama me pēhea e taea ai te wehewehe me te ako i ngā okana.
I. Te Mātāpono o te Whakapūtanga Rerekētanga
Mā te whakamahi i te centrifugation rerekē ka whakamahia ngā rerekētanga o te rahi, te āhua, me te mātotoru i waenga i ngā wāhanga pūtau hei wehewehe i a rātou. Mā te whakamahi i ngā kaha centrifugation, ka taea te wehewehe i ngā wāhanga i runga i ō rātou tere whakatō. Kei roto i te tukanga he maha ngā mahi centrifugation i ngā tere piki haere, e taea ai te wehe haere i ngā whekau motuhake.
II. Te Whakatū i tētahi Kawa Whakaterenga Rerekē
Hei whakahaere i te centrifugation rerekētanga kia whai hua, me āta hoahoa e ngā kairangahau tētahi tikanga e arotau ana i te wehenga o ngā whekau. Kei roto i tēnei ko te whiriwhiri i te tere, te roa, te pāmahana, me te reo e tika ana. Hei tāpiri, he mea nui te whakamahi i ngā arai tika me te whakarite i te ōritetanga o te tauira hei karo i te rerekētanga o te whakamātautau.
III. Ngā Hipanga Whakapūtanga Rerekē
1. Hipanga 1: Te Whakaōrite
Ko te taahiraa tuatahi i roto i te centrifugation rerekē ko te homogenization, arā, ka pakaruhia ngā pūtau, ngā kiko rānei kia tukuna ai ō rātou wāhanga. Ko te tikanga ka tutukihia tēnei mā roto i ngā tikanga miihini, pērā i te huri, te sonication rānei, hei hanga i tētahi whakatārewatanga pūtau, i tētahi homogenate rānei.
2. Hipanga 2: Te Whakapūngao Tere-Papaku
Ka tukuna te ranunga ki te taahiraa whakatere tere-iti hei tango i ngā para o te pūtau me ngā pūtau kāore anō kia pakaru. Mā te whakatere i te tere tata ki te 1,000 ki te 2,000 × karamu mō te wā poto ka pakaru te rauemi taumaha, ka waiho he waikeri kua whakakiia ki ngā whekau koretake.
3. Hipanga 3: Te Whakapūtanga Rerekētanga
Ko te wai i tangohia mai i te taahiraa whakapūngao tere-iti ka whakawhitia ki tētahi ngongo hou, ā, ka tukuna ki tētahi whakapūngao tere-nui ake. Ko te whāinga o tēnei taahiraa he wehewehe i ngā whekau i runga i ō rātou kiato. Hei tauira, ko ngā mitochondria ka pupuhi i ngā tere mai i te 6,000 ki te 10,000 × g, ko ētahi atu whekau ka noho tonu i roto i te wai.
4. Hipanga 4: Te Wehewehenga Anō
Hei wehe i ngā whekau motuhake, hei whakakore rānei i ngā wāhanga pūtau-iti, ka taea te mahi i tētahi atu wāhanga o te centrifugation rerekē. Ko te tikanga o tēnei ko te tango i te wai i runga ake i te taahiraa o mua, ka tukuna ki te kaha centrifugal teitei ake. Mā te whakatikatika i te tere me te roa, ka taea e ngā kairangahau te whakarei ake i ngā whekau motuhake me te whakaiti i te poke.
5. Hipanga 5: Te Whakama me te Tātari
I muri i te centrifugation rerekētanga, ka taea te pure anō i ngā wāhanga kua whakareihia ki ngā whekau motuhake mā te whakamahi i ngā tikanga tāpiri pēnei i te centrifugation pikinga matotoru, te immunoprecipitation rānei. Hei whakamutunga, ka taea te tautuhi pai i ngā whekau motuhake mā te whakamahi i te microscopy, te proteomics, te genomics, me ētahi atu tikanga motuhake.
IV. Ngā Whakamahinga o te Whakapūtanga Rerekētanga
He tikanga matua te centrifugation rerekē i roto i ngā momo mara o te pūtaiao koiora. He whānuitia ōna whakamahinga, mai i te rangahau pūtau taketake ki ngā rangahau tātaritanga me te rongoā. Anei ētahi whakamahinga rongonui:
1. Te Rangahau i ngā Mahi a ngā Organelle
Mā te centrifugation rerekē ka taea e ngā kairangahau te tiki i ngā okana kua purea, hei āwhina i te tautuhi i ā rātou mahi ā-tinana. Mā te ako i ngā okana kua wehea, ka taea e ngā kaipūtaiao te wetewete i ō rātou tūranga i roto i ngā tukanga pēnei i te pākia o te tinana, te hanga pūmua, te whakaputa pūngao, me te homeostasis pūtau.
2. Te tūhura i ngā tikanga mate
He mea nui te mārama ki te pānga o ngā mate ki te hanganga me te mahi a ngā whekau pūtau mō te whakawhanake i ngā maimoatanga. Ka taea te whakamahi i te centrifugation rerekētanga hei whakataurite i ngā whekau pūtau mai i ngā pūtau hauora me ngā pūtau mate, hei whakarato māramatanga ki ngā tikanga mate me ngā whāinga rongoā pea.
3. Te Rangahau i te Whanaketanga Pūtau
I te wā o te whānautanga o te kukune, te rerekētanga rānei o te kiko, ka rerekē te whakaritenga me te hanganga o ngā whekau. Mā te centrifugation rerekē ka taea e ngā kairangahau te tirotiro i ēnei whakarerekētanga hihiri, ka wetewete i ngā tukanga uaua e uru ana ki te whanaketanga me te rerekētanga o te pūtau.
4. Te tautuhi i ngā tohu koiora
He taputapu tino whai hua te centrifugation rerekētanga me te tātari proteomic mō te tautuhi i ngā tohu koiora e pā ana ki ngā mate maha. Mā te ako i ngā whekau, ka taea e ngā kairangahau te kite i ngā pūmua e noho motuhake ana, e whakarerekētia ana rānei i roto i ngā āhuatanga mate, hei āwhina i te tautuhi wawe me te aroturuki maimoatanga.
5. Ngā Pūnaha Tukunga Rongoā
I roto i te ao tuku rongoā, he mea nui te mārama ki te taunekeneke a ngā kaikawe rongoā me ngā momo whekau rerekē. Mā te centrifugation rerekē ka taea te wehe i ngā whekau ūnga, ka hoatu he māramatanga ki te wāhi e tū ai te rongoā, ngā tikanga tukunga, me ngā āwangawanga paitini pea.
Whakamutunga
He mea nui te mahi a te centrifugation rerekētanga ki te wehewehe i ngā whekau, e āhei ai ngā kairangahau ki te wetewete i ā rātou mahi, āhuatanga, me ngā tūranga i roto i ngā tukanga pūtau. Mā te hoahoa āta i ngā kawa me te whakamahi i ngā mahi centrifugation raupapa, ka taea e ngā kaipūtaiao te whakarei ake i ā rātou tauira mō ngā whekau motuhake, ka āwhina i te tātaritanga me te tūhuratanga o ēnei wāhanga pūtau nui. I te haere tonu o te whanaketanga o te hangarau, ka noho tonu te centrifugation rerekētanga hei tikanga matua i roto i te koiora pūtau, ka taea ai ngā kitenga me ngā whanaketanga i roto i ngā momo mara rangahau.
