Te Tere o te Pūwero hei Wehewehe i ngā Ribosome Koreutu: He Tikanga Matua mō te Rangahau Koiora Ngota
Kupu Whakataki:
He mahi nui tā ngā ribosome kore utu i roto i te hanganga pūmua, ā, he mahi matua te wehe i a rātou mai i ētahi atu wāhanga pūtau i roto i te rangahau koiora ngota. E tūhuratia ana e tēnei tuhinga te hiranga o te tere o te centrifuge i roto i te wehewehe i ngā ribosome kore utu, me te whakaatu i ngā tikanga me ngā whakaaro mō tēnei tukanga.
I. Te Mārama ki ngā Ribosome Koreutu:
Hei mārama ki te hiranga o te tere o te centrifuge i roto i te wehewehe i ngā ribosome kore utu, he mea nui kia mārama ki te āhua me ngā mahi a ēnei wāhanga pūtau. Ko ngā ribosome kore utu he hanganga iti, he kirikiri e kitea ana e rere noa ana i roto i te cytoplasm, e kawenga ana mō te hanga pūmua i roto i te pūtau. Kāore he hanganga here-kiri-kiri i roto i a rātou, e wehewehe ana i a rātou mai i ngā ribosome e piri ana ki te reticulum endoplasmic. Mā te wehewehe i ngā ribosome kore utu ka taea te mārama ake ki ō rātou tūranga nui i roto i te hanga pūmua pūtau.
II. Ngā Mātāpono o te Whakapūtanga:
He tikanga whānui te whakamahi i te centrifugation hei wehewehe i ngā wāhanga pūtau i runga i te rahi, te mātotoru, me te taumaha ngota. Kei roto i tēnei ko te whakamahi i te kaha centrifugation, i hangaia e te hurihuri i ngā tauira i ngā tere teitei, hei wehewehe i ngā para pūtau, ngā whekau, me ngā macromolecules. Hei whakatutuki i te wehenga o ngā ribosomes kore utu, he mea nui kia arotauhia te tere me te roa o te centrifugation, nā te mea he nui te pānga o ēnei āhuatanga ki te pai o te wehenga.
III. Te Arotautanga o te Tere o te Pūwero:
A. Te Tūhura i ngā Awhe Tere:
Ko te whakatau i te tere tika o te centrifuge mō te wehewehe i ngā ribosome kore utu e whakawhirinaki ana ki ētahi āhuatanga, tae atu ki te momo tauira me te taumata parakore e hiahiatia ana. I te nuinga o te wā, ka mahi ngā kairangahau i roto i te whānuitanga o ngā tere, mai i ngā tere iti ki te whakakore i ngā para pūtau nui ake, ā, ka piki haere mārire. Ko te whānuitanga tere pai rawa atu i waenga i te 10,000 ki te 100,000 xg, me ngā rerekētanga i runga i ngā āhuatanga motuhake o te tauira.
B. Ngā Āhuatanga Tauira:
He rerekē ngā taumata o te nui o ngā ribosome i roto i ngā pūtau me ngā kiko rerekē. Hei tauira, ko ngā kiko he nui ake te tere o te pākia o te tinana, pērā i ngā pūtau uaua, ate rānei, he nui ake ngā ribosome kei roto. Me whakarerekē te tere o te centrifuge kia whiwhi ai i te pai o te wehenga e hiahiatia ana.
IV. Ngā Tikanga Whakapūmau mō te Wehewehenga Ribosome Koreutu:
A. Te Whakarite Tauira:
Hei wehe angitu i ngā ribosome kore utu, he mea nui te whakarite tauira tika. Me whakamahi i ngā tikanga wehewehe pūtau, pērā i te sonication, te whakakorenga pūtau rānei mā te whakamahi i ngā hopi horoi, hei wawahi i ngā pūtau me te tuku i ō rātou ihirangi. Muri iho, ka haere ngā tauira kua pakaru ki roto i tētahi raupapa o ngā mahi centrifugation hei tango i ngā paru, ka puta he waikura mārama kei roto ngā ribosome.
B. Te Whakapūtanga Rerekētanga:
Ko te tikanga whakapūtā rerekē, he tikanga e whakamahia whānuitia ana, he maha ngā takahuri whakarārangi i ngā tere whakapūtā e piki haere ana. Mā tēnei tikanga ka taea e ngā kairangahau te wehe i ngā ribosome mai i ētahi atu wāhanga pūtau me te whai hua. Mā ngā takahuri tere iti tuatahi ka tangohia ngā para pūtau, ā, ka whai ake ko ngā tere waenga hei wehe i ngā whekau me ngā pūmua pūtau nui ake. Hei whakamutunga, ka whakamahia ngā takahuri tere teitei hei whiwhi i te wāhanga e hiahiatia ana e whai kiko ana i roto i ngā ribosome kore utu.
C. Te Whakapūtanga Rōrahi:
Mā te whakamahi i te pūwero whakarara ka whakamahia he rauemi whakarara kiato, pērā i te sucrose, te cesium chloride rānei, hei wehewehe i ngā ribosome i runga i ō rātou kiato pōkarekare. Mā te whakatakoto i te tauira ki runga i te whakarara kiato me te pūwero i te tere whakahaeretia, ka taea te wehewehe i ngā ribosome me te taumira teitei ake. Ka tukuna e tēnei tikanga he parakore ake, ā, ka taea te wehe i ngā momo ribosome rerekē i runga i ō rātou tere whakatō.
V. Ngā Take e Pā Ana ki te Arotau i te Tere o te Pūwero:
A. Te Rōrahi Tauira:
He nui te pānga o te rahinga o te tauira ki te tere o te centrifuge. Tērā pea ka roa ake te wā centrifuge, ka nui ake rānei ngā tere e hiahiatia ana mō ngā rahinga tauira nui ake kia tika ai te wehenga. Heoi, he mea nui kia mōhiotia ko te tere nui rawa, ko te roa rānei o te wā centrifuge ka arahi pea ki te kino o te ribosome me te pā ki ngā whakamātautau o muri mai.
B. Momo Rotor:
He rerekē ngā tere me ngā kaha mōrahi o ngā rotor centrifuge rerekē. He mea nui te whiriwhiri i tētahi rotor tika hei karo i ngā kino o ngā taputapu, hei pupuri hoki i te wehenga tika. He mea nui kia tirohia te pukapuka kaiwhakamahi a te centrifuge me ngā taunakitanga a te kaihanga ina whiriwhiria ana te momo rotor i runga i te tere e hiahiatia ana me te rahinga tauira.
Whakatau:
He mea nui te arotau i te tere o te centrifuge mō te wehenga angitu o ngā ribosome kore utu, kia taea ai te ako i tā rātou mahi i roto i te hanganga pūmua pūtau. Mā te whai i ngā tikanga motuhake me te whakaaro ki ngā āhuatanga tauira, ka taea e ngā kairangahau te wehewehe i ngā ribosome kore utu, me te whakarato i ngā māramatanga whai hua ki ā rātou mahi me ngā taunekeneke i roto i te taiao pūtau.
