Bwe tufuna omusujja oba omusujja, gutereera mu nnaku ntono, nedda? Wali weebuuzizzaako engeri ekyo gye kibaawo? Tulina n’eggye eddene munda mu mibiri gyaffe, erirwanyisa obuwuka obuleeta endwadde okuva ebweru. Omu ku bajaasi abasinga okuba ab’enjawulo mu ggye eryo ayitibwa ‘antibodies’. Leero tugenda kwogera ku kika kya antibody eky’enjawulo, ‘Polyclonal Antibodies’. Wadde erinnya lino liwulikika nga lya ssaayansi katono, emboozi nnyangu nnyo. Ka tulabe ebikwata ku bikuuma omubiri bino.
Mu ngeri ennyangu, obutoffaali buno obuziyiza endwadde (polyclonal antibodies) kye ki?
Polyclonal antibodies ze puloteyina entonotono ezibeera ekitundu ku baserikale baffe abaserikale b’omubiri. Okusingira ddala, zikolebwa ekibinja ky’obutoffaali obuyitibwa obutoffaali bwa plasma B.
Kati kino ka twongere okwanguyizaako katono. Kuba akafaananyi ng’omulabe azze mu nsi yo. Okusobola okuzuula omulabe oyo, waliwo ‘obubonero’ obw’enjawulo ku mubiri gwe. Kye kimu n’obuwuka, akawuka oba obuwuka, bwe buyingira mu mubiri gwaffe. Akawuka ako kalina ‘akabonero’ ak’enjawulo ku ngulu. Mu busawo, akabonero kano tukayita ‘antigen’ .
Abaserikale baffe ab'omubiri bwe balaba antigen eno, bagitegeera ne bagamba nti, "Oh... ono si omu ku ffe, muntu ava bweru." Olwo eggye lyaffe, kwe kugamba, antibodies, ne ligenda mu bikolwa.
Naye waliwo akatono akalala wano. Ku antigen emu, kwe kugamba, ku mubiri gw’omulabe omu, waliwo ebifo ebiwerako antibodies zaffe ze zisobola okukwata. Nga bwe waliwo ebituli ebiwerako ebisumuluzo okuyingira mu mulyango gumu. Buli kimu ku binnya bino tukiyita ‘epitope’ .
Ekigambo ‘polyclonal’ kitegeeza ‘okuva mu bika eby’enjawulo’. Kale, obutafaali obuziyiza endwadde (polyclonal antibodies) nkuŋŋaanya y’ebika by’obuziyiza bingi eby’enjawulo ebisobola okulumba ebifo eby’enjawulo (epitopes) ku mulabe omu (antigen). Kino kikendeeza nnyo ku mikisa gy’omulabe okuwonawo.
Wadde nga bino bikolebwa mu butonde mu mibiri gyaffe, okukozesebwa mu ddagala oluusi biggibwa mu mibiri gy’ebisolo ng’enkazaluggya n’endiga, oba mu musaayi gw’abantu abawonye endwadde ezimu.
Bino bikola bitya munda mu mubiri?
Enkola ya kino enyuma nnyo. Kilowoozeeko ng’ekisumuluzo n’enkwale.
1. Omulabe ayingira: Akawuka oba obuwuka buyingira mu mubiri gwaffe. Kirina ‘pigment’ ku ngulu. Zino ze antigens.
2. Ebikwata ku nkwaso: Naye buli nkwaso erina ebituli by’ebisumuluzo ebiwerako. Zino ze bitundu ebiyitibwa epitopes.
3. Eggye ly’ebisumuluzo lituuka: Amangu ddala ng’abaserikale baffe abaserikale balaba ekiwuka kino, kikola ‘ebika by’ebisumuluzo eby’enjawulo’ bingi ebiyingira mu buli kinnya. Eggye eryo ery’ebisumuluzo liyitibwa polyclonal antibodies.
4. Olutalo lutandika:Ebika by’ebisumuluzo bino eby’enjawulo (antibodies) byesiba ku bituli eby’enjawulo (epitopes) mu mubiri gw’omulabe. Balumba omulabe omu okuva mu bifo ebingi.
5. Asaanyaawo omulabe: Obuziyiza bwe bunywerera bwe buti, obutoffaali obulala mu baserikale b’omubiri busobola bulungi okutegeera n’okusaanyaawo omulabe ono.
Mu ngeri ennyangu, eky’enjawulo ekiri mu buziyiza obuziyiza endwadde (polyclonal antibodies) kwe kuba nti mu kifo ky’okulumba omulabe omu mu ngeri emu yokka, zimulumba okuva mu nsonda ez’enjawulo era mu ngeri ez’enjawulo. Kino kifuula abaserikale b'omubiri okuba ab'amaanyi ennyo era okukola obulungi .
Bino bikozesebwa ki mu ddagala?
Ng’oggyeeko okukolebwa mu butonde mu mibiri gyaffe, obuziyiza buno obuyitibwa polyclonal antibodies bukozesebwa okukola emirimu mingi emikulu mu busawo.
- Okuzuula: Ebimu ku bikeberebwa mu laboratory, nga ELISA ne immunohistochemistry, bikozesebwa okuzuula oba waliwo yinfekisoni oba kookolo.
- Ku kunoonyereza kwa ssaayansi: Abanoonyereza bakozesa bino okutegeera engeri emibiri gyaffe gye gikolamu n’engeri endwadde gye zikula.
- Okujjanjaba n’okuziyiza endwadde: Obuziyiza obuyitibwa Polyclonal antibodies bukozesebwa okujjanjaba embeera ng’eddagala erimu erisukkiridde, okulumwa omusota, n’endwadde ezimu ez’omusaayi.
| Enkola y’obujjanjabi | Ennyinyonnyola ennyangu |
|---|---|
| Eddagala eritta omusota (Antivenom) . | Zino zirimu obutoffaali obuziyiza endwadde obukoleddwa okuziyiza obutwa obuyingira mu mubiri ng’omusota guluma. |
| Plasma ewona | Plasma y’omusaayi gw’omuntu awonye obulwadde obusiigibwa erimu obutoffaali obuziyiza endwadde obuyitibwa polyclonal antibodies obukoleddwa okulwanyisa obulwadde obwo. Plasma eno eweebwa omulwadde okufuna obujjanjabi. |
| Digoxin abaserikale b’omubiri fab | Empiso eweebwa singa omuntu asusse okukozesa eddagala ly’omutima erya Digoxin. |
| Rho(D) ekirungo ekiziyiza endwadde ekya globulin | Eddagala lino liweebwa maama ow’olubuto alina ekika ky’omusaayi ekitali kya Rh okuziyiza ebizibu (rhesus isoimmunization) ebiyinza okubaawo singa ekika ky’omusaayi gw’omwana kifuuka Rh-positive. Era eweebwa ng’eddagala erijjanjaba obulwadde bw’omusaayi obuyitibwa ITP (immune thrombocytopenia). |
Njawulo ki eriwo wakati w’obutoffaali obuziyiza endwadde obuyitibwa polyclonal ne monoclonal antibodies?
Oyinza n’okuwulira ku ‘obuwuka obuziyiza endwadde obuyitibwa monoclonal antibodies.’ Wadde nga bino byombi bilumba antigens, waliwo enjawulo entono naye nga nkulu.
| Engeri | Obuziyiza obuziyiza endwadde (Polyclonal) . | Obulwadde obuziyiza endwadde obuyitibwa monoclonal antibodies (Monoclonal) . |
|---|---|---|
| Engeri gye kitondebwamu | Kikolebwa okuva mu kukuŋŋaanyizibwa kw’obutoffaali bwa B obw’ebika eby’enjawulo. | Zikolebwa mu laboratory okuva mu kkopi (clones) z’obutoffaali bumu obwa B. |
| Okuteeba | Zilumba epitopes (ebifo) eby’enjawulo ku antigen emu. | Kilumba epitope emu yokka entongole ku antigen emu. |
| Okufulumya | Bufunibwa mu butonde okuva mu musaayi gw’ebisolo oba abantu. | Guggibwa mu musaayi gw’ebisolo ne gukolebwamu obuwumbi n’obuwumbi bwa kkopi mu laboratory. |
| Enkula | Omutabula gw’obutoffaali obuziyiza endwadde obw’enjawulo. Omutindo guyinza okwawukana okusinziira ku kibinja. | Olw’okuba zonna za kika kya antibodies kye kimu, zibeera nnywevu nnyo era eby’obugagga byabwe tebikyuka. |
Birungi ki ebiri mu kino?
- Ensimbi entono ez’okukola: Zino nnyangu okukola okusinga antibodies eziyitibwa monoclonal antibodies, ezikolebwa mu ngeri enzibu mu laboratory.
- Obusobozi obulungi obw’okuzuula: Ne bwe kiba nti obungi bwa antigen mu sampuli butono nnyo , bino bisobola bulungi okugizuula kubanga esobola okwesiba mu bifo eby’enjawulo.
- High specificity: Olw’okuba antigen y’emu esiba ku bifo ebingi, eky’okuddamu kisinga kukwatagana.
Olwo tewali kizibu kyonna?
Kya lwatu nti waliwo n’ebizibu.
- Enjawulo mu mutindo: Olw’okuba zino zibeerawo mu butonde, wayinza okubaawo enjawulo mu mutindo wakati w’ekibinja ekimu eky’obutafaali obuziyiza endwadde n’ekirala. N’olwekyo, obulungi bwabyo buyinza okwawukana.
- Obusobozi bw’ebivuddemu ebirungi eby’obulimba: Oluusi, wabaawo okusobola okusalasala n’ekiziyiza ekirala ekifaananako n’ekiziyiza ekigendererwa. N’olwekyo, ebivudde mu kunoonyereza okw’obulimba bisobola okubaawo mu kukeberebwa.
- Allergic reactions: Obuziyiza obuyitibwa polyclonal antibodies obuva mu bisolo bwe bukozesebwa okujjanjaba abantu, wabaawo akabi k’okulwala alergy oba ebizibu ebirala.
Kale, nga bw’olaba, obuziyiza buno obuyitibwa polyclonal antibodies kitundu kikulu nnyo mu baserikale b’omubiri gwaffe, awamu ne mu ddagala. Zitera okukozesebwa mu kunoonyereza n’okukebera okuzuula obulwadde. Bw’oba olina ekibuuzo kyonna ku nsonga eno naddala ng’oweebwa bino olw’obujjanjabi obw’enjawulo, kirungi n’obuuza omusawo oba nnansi akunnyonnyola.
Obubaka Obutwala Awaka
- Polyclonal antibodies kibinja kya butonde obuziyiza obukolebwa ebika by’obutoffaali eby’enjawulo mu baserikale b’omubiri gwaffe.
- Bino bikola nga bilumba ebifo eby’enjawulo (epitopes) ku mulabe omu (antigen) ne biyamba okusaanyaawo omulabe oyo. Kino kifuula okuddamu okuba okw’amaanyi ennyo.
- Mu busawo, zikozesebwa okuzuula n’okunoonyereza, wamu n’okujjanjaba ng’obutwa bw’omusota n’okugema bamaama b’embuto abatalina Rh.
- Zino za njawulo ku antibodies eziyitibwa monoclonal antibodies, ezikolebwa mu laboratory okuva mu katoffaali kamu ne zilumba ekigendererwa kimu kyokka.
- Bw’oba olina ekikweraliikiriza ku bujjanjabi bwonna bw’oweebwa ku nsonga eno, buteese bulungi n’omusawo wo.
