Kei te piki haere te aro ki te tiaki kiri i te PDRN, engari kāore te ingoa INCI anake e whakaatu ana me pēhea te pūtake mai, te hanga rānei o tētahi kai.
I roto i te putea PDRN a Uniproma, ko te PDRN i ahu mai i te hāmana me te PDRN i hangaia anōtia kua tohua ko te DNA Konutai. Ahakoa he rite tonu te tohu INCI, he rerekē rawa ngā huarahi e rua i roto i te huarahi whakaputa, te whakahaere kounga me te tauine tuku.
Ko te PDRN i ahu mai i te hāmana he tīmatanga pūtaiao nui nā tōna hītori pumau puta noa i te rongoā whakaora, ngā tono ataahua me te tiaki kiri. I runga i tēnei tohutoro, i whakahaerehia e Uniproma he raupapatanga whānui me te whakataurite i ngā hua PDRN me te PN arumoni, me te whiriwhiri i te 99 ngā kongakonga ira tino pai mō te whanaketanga recombinant.
He rerekē te tangohanga tikanga mai i ngā kiko koiora, ka whai te PDRN recombinant i tētahi ara hanga whakahaeretia:
Kōwhiringa raupapatanga ūnga → hanganga plasmid → whakapūtanga moroiti → hopunga hua ūnga → purenga o raro
Whai muri i te whakapūtanga, ka hangaia ngā tukanga purenga o raro iho hei tango i ngā matū whakaputanga, ngā pūmua pūtau-kaihautū me te DNA pūtau-kaihautū, me te whakarato i tētahi atu taahiraa purenga mā te chromatography whakawhiti-katote. Ka tautokohia e tēnei tukanga whakahaeretia te parakore, te ōritetanga puranga me te whai i ngā āhuatanga hangarau.
Ka whakaitihia hoki e te hangahanga e ahu mai ana i te whakapūkara te whakawhirinaki ki ngā rauemi koiora o te wā, ā, ka whakaratohia he ara tauine mai i ngā rahinga whanaketanga ki te hanga arumoni.
Kua arotakehia hoki te whai huatanga i roto i te tinana ora. I muri i ngā rā 28 o te whakamahinga i te 0.1%, i whakaatuhia e te PDRN recombinant:
·Te whakahekenga o te TEWL o te 17.37%
·Te whakaiti i te whero o te 12.40%
·Te whakapai ake i te ngāwari o te kiri mā te 30.11%
·Te whakaiti i te maha o ngā kita o te 46.67%
E tautoko ana ēnei kitenga i tōna pūmanawa ki te whakatika i ngā ārai, te whakamarie, te whakakaha me te ārai i ngā kita.
Mō ngā kaihanga me ngā waitohu, ko te aromatawai i te PDRN he titiro ki tua atu i te ingoa INCI kia mārama ai ki te pūnaha whakaputa, ngā mana whakahaere kounga me te tauira tuku kei muri i te kai.
Ka whakarato a Uniproma i ngā tuhinga hangarau, ngā aratohu hanga, ngā mōhiohio kounga me te tautoko tuku arumoni mō te whanaketanga PDRN recombinant.
