Folasaga o Elisa Plate

2024-04-24

ELISA PALIT: I le Enzyme Linked Immunosorbent Assay (ELISA), o le mama, faʻatonuga ma le fua faatatau o antigens, antibodies, faʻailoga faʻamaʻi poʻo antigens o loʻo aʻafia i le immunological reaction; ituaiga pa'u, fa'atonuga ma Tulaga e pei o le malosi o le ionic, tau o le pH, le vevela o le tali ma le taimi o lo'o i ai se sao taua. E le gata i lea, o le pito i luga ole solid-phase polystyrene (Polystyrene) e avea o se ave taavale e taua foi i le adsorption o antigens, antibodies poʻo antigen-antibody complexes.

Antigens, antibodies ma isi biomolecules o loʻo faʻapipiʻiina i luga o le vaʻavaʻa e ala i le tele o auala, e aofia ai le adsorption passive e ala i le hydrophobic bonds, hydrophobic / ionic bonds, faʻapipiʻi faʻatasi e ala i le faʻaofiina o isi vaega faʻamalosi e pei o amino ma carbon group, ma e ala i suiga i luga. . Feso'ota'iga Hydrophilic pe a uma feusua'iga.


O leElisa Platae mafai ona vaevaeina i le 48-vaieli ma le 96-vaieli e tusa ai ma le numera o pu. O le mea masani e faʻaaogaina o le 96-well, lea e tatau ona filifilia e tusa ai ma lau faitau microplate.


E le gata i lea, o loʻo i ai mea e mafai ona faʻaaogaina ma e le mafai ona faʻaaogaina. Mo mea e le mafai ona fa'amavaeina, o pa'u i luga o le laupapa atoa e feso'ota'i fa'atasi. Ona, mo mea e mafai ona aveese, o paʻu i luga o le laupapa e vavae ese, ma o laupapa vavaeese E iai le 12-pu ma le 8-pu. E masani lava, e masani ona fa'aaogaina i aso nei o papatusi e fa'aigoaina enzyme. Afai na e fa'atauina muamua ni ipu fa'apena, e mafai ona e fa'atau mai ni fasi pepa fa'ailoga enzyme i le taimi nei.


E ui lava o microplates na faia e tagata gaosi eseese e foliga tutusa i le aotelega, o nisi faʻamatalaga laiti o le a eseese, e pei o le fausaga, ma isi. O le mea lea, a e faʻaaogaina Pe a filifili e faʻatau se microplate reader, e tatau foi ona e mafaufau pe o le a le foliga o lau microplate reader. Ae masani lava e fetuutuunai, na o nisi o le a eseese. Talu ai o mea o le enzyme plate e masani lava o le polystyrene (PS), ma o le polystyrene e le lelei le mautu o vailaʻau ma e mafai ona faʻamavaeina e le tele o vailaʻau faʻalaʻau (e pei o le aromatic hydrocarbons, halogenated hydrocarbons, ma isi), ma o le a faʻaleagaina e le malosi malosi. ma alkalis. , e le faʻasaʻo i gaʻo, ma faigofie ona sui lanu pe a uma ona faʻaalia i le malamalama ultraviolet, ia mautinoa ia faʻalogo i nei mea pe a faʻaaogaina leElisa Plata.
