Kua roa te umanga miraka e whakawhirinaki ana ki ngā tikanga whakamātautau tuku iho—pērā i te whakatipu moroiti, te titration matū, me te chromatography—hei whakarite i te haumaru me te kounga o ngā hua. Heoi anō, kei te piki haere te werohia o ēnei huarahi e ngā hangarau hou, inā koaWhakamātautau Ārai Mate Pūmua Hononga-Whākī (ELISA)ngā keteI mua i te whakaarotia he taputapu motuhake ngā kete ELISA, engari inaianei kua kitea he tere ake, he tika ake, he iti ake hoki te utu. Me tūhura tātou he aha te take e hurihia ai e te ELISA te whakamātautau miraka, me te whakakore i te pakiwaitara "he pai ake tonu ngā tikanga tawhito."
Ngā Here o ngā Tikanga Tuku Iho
Ahakoa he mea taketake ngā tikanga whakamātautau miraka tuku iho, he nui ngā ngoikoretanga kei mua i a rātou:
- Ngā Tukanga E Pau Ana te WāKo te whakatipu i ngā moroiti he maha ngā rā hei whakatipu i ngā pathogens (hei tauira, Listeria, Salmonella rānei), ā, ka whakaroa i ngā huringa whakaputa.
- Ngā Rerenga Mahi UauaKo ngā tikanga pēnei i te High-Performance Liquid Chromatography (HPLC) e hiahia ana ki ngā taputapu motuhake me ngā kaimahi whakangungua, ā, ka piki ake ngā utu.
- Te Tairongo itiHe uaua ki ngā whakamātautau matū te kite i ngā poke iti (hei tauira, ngā paturopi, ngā mate pāwera rānei), ā, ka tūpono pea he hua kino teka.
Ka ārai ēnei arai i te whakatutukitanga o ngā ture haumaru kai tino pakari (hei tauira, ngā paerewa a te FDA, a te EU rānei) ā, ka whakapiki ake i ngā mōrearea whakahoki mai.
Ngā Kete ELISA: Te Tūturutanga o te Whai Huatanga
Ka whakamahia e te hangarau ELISA ngā taunekeneke paturopi-paturopi hei kimi i ngā ngota ngota ūnga me te motuhaketanga kāore i te rite. I roto i te whakamātautau miraka, he rerekē ngā painga o ēnei:
1. Te Tairongo me te Motuhaketanga Kore e Taea te Whakataetae
Ka taea e ngā kete ELISA te tautuhi i ngā poke ingā wāhanga-mō-ia-piriona (ppb)ngā taumata—he mea nui mō te kimi i ngā toenga pērā i ngā aflatoxins, i te penicillin rānei i roto i te miraka. Mō ngā mate pāwera (hei tauira, te casein, te lactose rānei), ka whakaitihia e te ELISA ngā hapa tauhohenga whakawhiti, kia tika ai te tapanga mō ngā kaihoko tairongo.
2. Te Wā Huringa Tere
Ahakoa e roa ana ngā rā ki te whakatipu, ka puta ngā hua o te ELISA2–4 hāoraMā tēnei tere ka taea te aroturuki i te wā tūturu i te wā whakaputa, ka whakaiti i te wā kore mahi me te para. Hei tauira, ka taea e te wheketere miraka te whakamātautau i te miraka mata mō ngā toenga paturopi i mua i te tukatuka, ka karo i ngā panga puranga utu nui.
3. Te Huarahi Whakahaere me te Whai Huatanga Utu
Ngā tautoko a te ELISANgā whakatakotoranga pereti 96-puna, e āhei ai te whakamātautau i ngā tauira maha i te wā kotahi. Nā ngā pūnaha aunoa i whakaiti ake ngā utu mahi, ā, ka taea te whakawhanui mō ngā mahi nui. I kitea i roto i tētahi rangahau a te Journal of Dairy Science i whakaitihia e te ELISA ngā utu mō ia tauira mā te 40% ki te whakaritea ki te HPLC.
4. Ngāwari te Whakatutuki i ngā Ture
Kua whakamanahia ngā kete ELISA mō ngā paerewa o te ao (hei tauira, ISO 22174), kia māmā ake ai ngā arotake. Pērā i te kaihangaKwinbone tuku ana i ngā kete kua whaimanahia mō ngā EU MRL (Ngā Herenga Toenga Nui) me ngā paepae FDA, e whakahaere ana i ngā kaweake o te ao.
Te Whakakore i ngā Kōrero Pūrākau
E kī ana ngā kairīti kāore i te maha ngā mahi a te ELISA, he ngāwari rānei ki te whakaputa i ngā hua hē. Heoi anō, kua arohia ēnei āwangawanga e ngā whanaketanga:
Pūrākau 1"Ka kitea anake e te ELISA ngā pūmua."
Ko ngā kete hou o nāianei e aro ana ki ngā ngota iti (hei tauira, ngā homoni, ngā paitini) mā roto i ngā whakatakotoranga ELISA whakataetae.
Pūrākau 2"He tino ngawari rawa mō te whakamahinga ahumahi."
Mā ngā kete pakari me ngā tauhohenga pumau ka pono te whakamahi ahakoa i roto i ngā tautuhinga kore-taiwhanga.
Akoranga Take: ELISA i roto i te Mahi
I whakamahia e tētahi rōpū miraka Pākehā te ELISA mō te whakamātautau paturopi β-lactam. I mua i te whakamahi i ngā whakamātautau aukati moroiti, i pāngia rātou e ngā whakaroa 12-hāora me te 5% o ngā reiti kino-hē. Whai muri i te huri ki te ELISA, i heke te wā kitenga ki te 3 hāora, i heke ngā kino-hē ki te 0.2%, ā, i heke ngā utu whakahoki ā-tau mā te €1.2 miriona.
Te Anamata o te Whakamātautau Miraka
Ehara te ELISA i te whakakapi mō ngā tikanga tuku iho katoa engari he whakapai ake rautaki. I te tipu haere o te tono miraka me te whakawhāiti i ngā ture, ka whānui ake tana mahi ki te whakarite i ngā hua haumaru, kounga teitei. E puta ake ana ngā au hou pēnei iELISA maha-pūnaha(te kimi i ngā whāinga maha i te oma kotahi) mengā kaipānui ELISA kawete kupu whakaari ki te whakamana ake i te urunga atu ki te manapori.
Hei whakamutunga, kua whakakorea e ngā kete ELISA te pūrākau e kī ana kāore e taea te whakakapi i ngā tikanga tawhito. Mā te whakakotahi i te tere, te tika, me te utu whaitake, kei te whakatakoto rātou i tētahi paerewa koura hou mō te whakamātautau miraka—he paerewa e mau tonu ana ki ngā hiahia o te ahumahi me ngā tumanakohanga a te kaihoko.
