he aha te wehewehenga a te centrifugation
Te Whakapūngao: He aha tāna e Wehewehe ai?
He Kupu Whakataki ki te Whakapūtanga
He tikanga kaha te whakapūtanga e whakamahia whānuitia ana i roto i ngā momo mara pūtaiao, tae atu ki te koiora, te matū, me te rongoā. E ai ki tōna ingoa, ko te whakapūtanga ko te hurihuri i ngā tauira i ngā tere teitei. Ka hangaia e tēnei hurihanga he kaha whakapūtanga ka taea te wehewehe i ngā wāhanga rerekē o te ranunga i runga i tō rātou kiato, i te rahi rānei. Mā te whakamahi i ngā mātāpono o te whakapūtanga, ka taea e ngā kaipūtaiao te wehe me te pure i ngā matū ūnga mai i ngā ranunga uaua. I roto i tēnei tuhinga, ka tūhuratia e mātou ngā kaupapa matua o te whakapūtanga, ka matapakihia hoki ngā matū rerekē ka taea te wehewehe.
Te Wehewehe i ngā Wāhanga Toto: Te Mana o te Whakapūtanga
Ko tētahi o ngā whakamahinga tino noa o te centrifugation ko te wehenga o ngā wāhanga toto. Ko te toto he mea tito mai i ngā toto whero (erythrocytes), ngā toto ma (leukocytes), ngā pereti toto, me te plasma. Hei tiki i ngā wāhanga motuhake mō ngā kaupapa tātaritanga, rongoā rānei, he mea nui te centrifugation. Mā te huri i te toto i roto i te centrifuge motuhake, ka whakapūpūhia ngā toto whero ki raro, ka hanga he paparanga e mōhiotia ana ko te hematocrit. I runga ake i te paparanga hematocrit, ka puta te kahu pūhuruhuru, he mea tito mai i ngā toto ma me ngā pereti toto. Hei whakamutunga, ko te plasma, te wāhanga wai o te toto, kei te paparanga o runga. Mā tēnei wehenga ka taea te wehe i ngā wāhanga toto rerekē mō te tātaritanga, te tukatuka atu rānei.
Te Whakapūtanga Rerekētanga: Te Wehewehe i ngā Organelles Pūtau
He wāhanga nui ngā whekau pūtau i roto i ngā pūtau e mahi ana i ngā mahi motuhake. He maha ngā wā me wehewehe, me ako hoki e ngā kaipūtaiao ēnei whekau kia pai ake ai te mārama ki ngā tukanga pūtau. Ko te centrifugation rerekē he tikanga e whakamahi ana i ngā momo matotoru o ngā whekau hei wehewehe i a rātou. Mā te tuku i ngā homogenate pūtau, i ngā tangohanga rānei ki roto i tētahi raupapa o ngā mahi centrifugation i ngā tere rerekē, ka taea te wehewehe i ngā whekau ki ngā wāhanga motuhake. Hei tauira, ko te centrifugation tuatahi i te tere iti ka tango i ngā hanganga pūtau nui rawa atu, pērā i ngā karihi me ngā para. Ka taea e ngā oma i muri mai i ngā tere teitei ake te whakakōpiri i ngā mitochondria, te endoplasmic reticulum, ngā lysosomes rānei ki roto i ngā wāhanga motuhake. Mā tēnei tikanga ka taea e ngā kairangahau te ako i ngā whekau takitahi me ā rātou mahi.
Te Wehewehe i te DNA mā te Whakapūtanga: He Tikanga Hurihuri
I roto i te mara o te koiora ngota, he taahiraa matua te wehenga DNA i roto i ngā whakamātautau, i ngā tātaritanga rānei. Kua hurihia e te centrifugation te tukanga tango DNA, kia pai ake ai, kia whai hua ai hoki i te wā. I roto i tēnei tikanga, ka tukuna he ranunga kei roto ko te DNA, ngā pūmua, me ētahi atu wāhanga pūtau ki te centrifugation. Nā te mea he ngota roa, he rite ki te miro te DNA, ka tere ake te puta mai i te wairewa i ētahi atu matū ina whakamahia te kaha centrifugal. Mā te āta whakahaere i ngā āhuatanga centrifugal, ka taea e ngā kaipūtaiao te whiwhi DNA parakore ka taea te whakamahi mō ngā rangahau ira, te raupapatanga, me ētahi atu tikanga ngota rānei.
Te Wehewehe i ngā Wāhanga Pūtau: Te Tūranga o te Whakapūtanga Rerekētanga Kiato
Mā te whakamahi i te pūwero mā te whakamahi i te rauemi pikinga mātotoru ka taea te wehewehe i ngā wāhanga he rite te mātotoru engari he rerekē te rahi. Mā te hanga i tētahi rauemi he pikinga mātotoru (teitei ake i raro, iti iho i runga), ka taea e ngā kaipūtaiao te tirotiro i te hekenga o ngā wāhanga rerekē i a rātou e tae ana ki ō rātou tūranga taurite i runga i te mātotoru. Hei tauira, ina whakamahia ki tētahi ranunga o ngā pūmua i roto i tētahi pikinga mātotoru, ka totohu ngā pūmua taumaha ki raro, ko ngā mea māmā ake ka rere ki runga. He tino whai hua tēnei tikanga mō te wehewehe i ngā lipoprotein i roto i ngā rangahau cholesterol, te wehe rānei i ngā huaketo.
Whakatau:
He tikanga whānui te centrifugation, he maha ngā whakamahinga i roto i te rangahau pūtaiao me te tātaritanga hauora. Kua noho hei wāhanga nui o ngā tikanga taiwhanga, e āhei ai ngā kaipūtaiao ki te wehewehe i ngā matū rerekē i runga i ō rātou kiato, i ō rātou rahi rānei. Mai i te wehewehe i ngā wāhanga toto ki te wehe i ngā whekau pūtau me te DNA, kei te whai wāhi tonu te centrifugation ki te whakatairanga i te māramatanga pūtaiao me te whakapai ake i ngā mahi hauora. Mā te whakamahi i te mana o te kaha centrifugal, ka taea e ngā kairangahau te wehe me te pure i ngā wāhanga ūnga, ka whakatuwhera i te ara mō ngā kitenga hou me ngā whanaketanga i roto i ngā mara rerekē.
