Me pēhea te wehewehe i ngā lysosome mai i ngā peroxisome mā te centrifugation
He Kupu Whakataki ki ngā Lysosome me ngā Peroxisome
Ko ngā lysosomes me ngā peroxisome he whekau pūtau motuhake e rua, he rerekē ā rātou mahi, ā, he mahi nui tā rātou i roto i te pākia o te pūtau me te homeostasis. Ko ngā lysosomes he whekau e herea ana ki te kiriuhi, kī tonu i ngā whākōkī nakunaku e kawenga ana mō te wawahi i ngā para pūtau, ngā matūriki ke, me ngā mate pukupuku. Ko ngā peroxisome, i tētahi atu taha, e whai wāhi ana ki ngā tauhohenga pākia, inā koa ko ērā e pā ana ki te tango paitini me te pākia o te ngako. Hei ako motuhake i ēnei whekau, ko tētahi tikanga e whakamahia whānuitia ana ko te centrifugation. I roto i tēnei tuhinga, ka tūhuratia e mātou me pēhea te whakamahi i te centrifugation hei wehe angitu i ngā lysosomes mai i ngā peroxisome.
Ngā Mātāpono me ngā Tikanga Whakapūtātanga
He tikanga kaha te centrifugation e whakamahia ana hei wehewehe i ngā wāhanga rerekē o te ranunga kanorau i runga i tō rātou rahi, te mātotoru, me te āhua. Ka mahi i runga i ngā mātāpono o te whakatōputanga, arā, ka tere ake te taunga o ngā matūriki taumaha i raro i te mana o te kaha centrifugation. Hei wehewehe i ngā lysosome mai i ngā peroxisome, ka taea te whakamahi i ngā tikanga centrifugation rerekē, pērā i te centrifugation rerekē me te centrifugation gradient density.
Te Whakapūtanga Rerekētanga: Te Tango i ngā Lysosome me ngā Peroxisome
Ko te centrifugation rerekē he raupapa o ngā mahi centrifugation i ngā tere me ngā roanga rerekē hei wehewehe i ngā organelles i runga i tō rātou kiato. Anei te whakamahinga hei tango i ngā lysosomes me ngā peroxisomes:
Hipanga 1: Te Whakaōrite
Ko te taahiraa tuatahi ko te pakaru mārire i ngā pūtau me te tuku i ō rātou ihirangi mā te whakamahi i te tikanga homogenization. Ka taea tēnei mā te sonicating, mā te whakamahi rānei i tētahi homogenizer motuhake. Ko te ranunga hua ka kiia ko te homogenate.
Hipanga 2: Te Whakapūtanga Tere-Pai
Kātahi ka tukuna te ranunga ki te porotītaha tere-iti (tata ki te 1,000-2,000 xg) mō te wā poto. Mā tēnei mahi ka wehea ngā para pūtau nui ake me te wāhanga karihi mai i ngā whekau katoa kei roto i te ranunga.
Hipanga 3: Te Whakapūtanga Tere-Waenga
Ko te wai i tangohia mai i te taahiraa whakapūnga tere-iti ka tukuna ki te whakapūnga tere-waenga (tata ki te 10,000 xg) ki te whakapūnga i ngā whekau taumaha pēnei i ngā lysosome me ngā peroxisome. Ko te hua o tēnei taahiraa he pirepire kei roto ēnei whekau.
Hipanga 4: Horoi me te Whakarewa anō
Ka horoia te pirepire i whiwhihia i te taahiraa o mua ki tētahi otinga ārai e tika ana, kātahi ka whakatārewatia anō kia whiwhi ai i tētahi wāhanga lysosome me peroxisome kua parakoretia.
Te Whakapūtanga o te Rerekētanga Matotoru: Te Whakatikatika i te Wehenga
Ko te centrifugation mātotoru he tikanga centrifugation matatau e āhei ai te purenga me te whakapai ake i ngā lysosome me ngā peroxisome. I roto i tēnei tikanga, ka hangaia he mātotoru mā te whakamahi i tētahi otinga hanga-mātotoru pērā i te sucrose, te iodixanol rānei. Anei te whakamahinga:
Hipanga 1: Te Whakarite i te Rōrahi Matotoru
Ka whakaritea he rauemi whakarara matotoru, pērā i te sucrose, i roto i tētahi ngongo centrifuge, me ngā matotoru rerekē mai i runga ki raro, mai i raro rānei ki runga. Ka āta whiriwhiria te hanganga me te matotoru o te rauemi whakarara, kia māmā ake ai i ngā peroxisome engari kia matotoru ake i ngā lysosomes.
Hipanga 2: Te Whakatakotoranga o te Tauira
Ko te wāhanga lysosome me te peroxisome kua whakatārewatia anō i whiwhi mai i te centrifugation rerekētanga ka ata whakatakotoria ki runga i te reo pikinga kiato.
Hipanga 3: Te Whakapūngao
Kātahi ka tukuna te ngongo ki te centrifugation tere-teitei (ultracentrifugation) hei wehewehe i ngā lysosome me ngā peroxisome i runga i ō rātou kiato pōkarekare. I te wā o te centrifugation, ka neke ngā whekau i roto i te reo kia tae rā anō ki tētahi rohe e ōrite ana tō rātou kiato pōkarekare ki te kiato o te reo e karapoti ana, ka hanga he roopu motuhake.
Te Tātari me ngā Whakamahinga Anō
I muri i te wehenga angitu, ka taea te tātari anō i ngā wāhanga lysosome me peroxisome i whiwhi mā te whakamahi i ngā tikanga maha hei aromatawai i tō rātou parakore, te rahi, te hanganga, me ngā āhuatanga mahi. Mā ngā tikanga pēnei i te karu hikohiko, te immunocytochemistry, me ngā whakamātautau ngohe whākōkī ka taea te whakarato i ngā māramatanga whai hua ki ngā wāhanga kua wehea, hei whakaū i tō rātou tuakiri me te parakore.
Haunga ngā kaupapa rangahau, ko te kaha ki te wehewehe i ngā lysosomes me ngā peroxisomes mā te centrifugation he whakamahinga anō hoki i roto i ngā tātaritanga hauora, te whakawhanaketanga rongoā, me ngā wawaotanga rongoā. Mā te mārama ake ki ngā mahi a ēnei whekau, ka taea e ngā kaipūtaiao te tūhura i ngā rautaki rongoā hou e aro ana ki ngā mate lysosomal, peroxisomal rānei, pērā i ngā mate rokiroki lysosomal, ngā mate biogenesis peroxisome rānei.
Hei whakamutunga, ko te wehenga o ngā lysosomes mai i ngā peroxisome mā te whakamahi i ngā tikanga centrifugation, pērā i te centrifugation rerekētanga me te centrifugation gradient density, he huarahi nui i roto i te rangahau koiora pūtau. Mā ēnei tikanga ka taea e ngā kaipūtaiao te tiki i ngā wāhanga parakore o ngā lysosomes me ngā peroxisomes, hei āwhina i te mārama ki ō rātou tūranga takitahi, ngā ara metabolic, me ngā wawaotanga rongoā pea mō ngā mate e pā ana.
