Dɛn ne ELISA? Ɛnyɛ den koraa!

Sɛ yɛbɛka no tiawa a, ELISA yɛ ɔkwan titiriw bi a wɔfa so yɛ nhwehwɛmu wɔ aduruyɛdan ahorow mu. Ɛyɛ adwuma te sɛ detective. Ɛhwehwɛ nneɛma bi wɔ yɛn nipadua mu, te sɛ antibodies, antigens , proteins, ne hormones , na ɛkyerɛ emu dodow a yɛwɔ.

Nhwehwɛmufo frɛ eyi ELISA sɛ sika kɔkɔɔ gyinapɛn a wɔde yɛ nipadua mu nkwammoaa a ɛko tia nyarewa . Ɛne sɛ, ɛyɛ ɔkwan a wotumi de ho to so yiye na ɛyɛ pɛpɛɛpɛ.

So wunim sɛ nyinsɛn mu nhwehwɛmu a wɔyɛ wɔ fie mpo gyina ELISA kwan yi so? Wɔhwehwɛ sɛ hormone bi a wɔfrɛ no human chorionic gonadotrophin (HCG) , a wɔsan frɛ no ‘nyinsɛn hormone’ wɔ hɔ.

Enti, dɛn ne saa nipadua no mu tumi a ɛko tia nyarewa yi?

Okay, afei momma yɛnhwɛ nea immunoassays yɛ. Eyinom yɛ sɔhwɛ ahorow a egyina nkitahodi a ɛda antigens ne antibodies ntam wɔ aduruyɛdan mu tebea horow mu (kyerɛ sɛ, wɔ lab mu, ɛnyɛ wo nipadua mu) so.

Sɛ yɛbɛte eyi ase a, ɛho hia sɛ wudi kan te sɛnea antibodies ne antigens yɛ adwuma wɔ wo nipadua mu no ase.

Enti, wɔ immunoassays mu no, nyansahufo a wɔwɔ lab no de antigens anaa antibodies a wɔwɔ wɔ wɔn nsam di dwuma de sɔ hwɛ sɛ antigen anaa antibody pɔtee bi wɔ nsu a wɔagye afi wo hɔ (e.g., mogya nhwɛsode) mu. Ate aseɛ?

Sɔhwɛ ahorow a wɔde ELISA kwan no di dwuma no tumi hu sɛ antigens ne antibodies pɔtee bi wɔ hɔ.

Dɛn na wɔde ELISA kwan no di dwuma?

Wɔde ELISA kwan no na ɛyɛ aduruyɛ mu nhwehwɛmu ahorow pii. Nanso adeɛ a ɛho hia paa ne sɛ wo lab amanneɛbɔ no renka ‘ELISA sɔhwɛ’ ho asɛm.

Ade biako a wɔtaa de ELISA di dwuma ne sɛ wobehu nnuru a ɛko tia nyarewa na wɔasusuw. Nhwɛsoɔ:

Afoforo a wɔtaa de ELISA kwan no di dwuma ne:

Ɔkwan bɛn so na saa ELISA kwan yi yɛ adwuma? Ɛyɛ nwonwa!

Okay, afei momma yɛnhwɛ sɛnea ELISA sɔhwɛ yi yɛ adwuma. Nsonsonoe nketenkete bi wɔ hɔ a egyina sɛ ebia ɛrehwehwɛ antibodies anaa antigens so . Momma yɛmmɔ mmɔden sɛ yɛbɛte eyi ase denam nhwɛso a yɛbɛfa so ahwehwɛ nnuru a ɛko tia nyarewa no so. ELISA sɔhwɛ dodow no ara yɛ automated - kyerɛ sɛ, adwuma dodow no ara yɛ nea mfiri na ɛyɛ. Nanso sɛ yɛbɛte saa kwan yi ase a, momma yensusuw sɔhwɛ bi a yɛde nsa yɛ ho.

Fa no sɛ wɔde ELISA kwan so reyɛ HIV (human immunodeficiency virus) nhwehwɛmu, na wode mogya ama wo dedaw. Nea edi kan no, aduruyɛ mu nhwehwɛmubea nyansahufo anaa mfiridwumayɛfo de HIV mmoawa no fã bi (eyi ne nea ɛyɛ adwuma sɛ antigen) gu sɔhwɛ afiri anaa plastic mprɛte so.

Afei, nyansahufo no de antibody foforo ka ho, saa antibody a ɛto so abien yi ‘hu’ saa HIV antibodies no. Ɛne sɛ, saa antibody a ɛto so abien yi kyekyere HIV antibody biara a kan no akyekyere antigen no. Saa antibody a ɛto so abien yi ne enzyme (ade bi a ɛma nnuru yɛ adwuma ntɛmntɛm) wɔ abusuabɔ.
