Abstract

The ELISA assay is an antigen-antibody reaction system which applicates an antibody coupled enzyme with the substrate is directly proportional to the amount of antibody or antigen present in the sample being tested. lmmunassay was the linkage of solu be antigen or antibody to an insoluble soild phase in a way in which reactivity of the iımnunological component was retained. This was the basis of the techniques known ELISA (Enzyme Linked lmmunosorbent Assay) pioneered by Engvall and colleaques Van Weemen and Schuurs (18). With the appropriate assay can be rcmarkably quick and easy yielding infommtion that would be diffıcult to .detennine by the other tecniques (21 ). The ELISA was fırst introduced in the early 1970's andisa highly sensitive method for assaying either antigens or antibodies. In principle the assay is analogus to radio-immunoassay (RIA), the only major difference being to use of an enzyme other that an isotope. Heterogenous enzyme-immunoassays combine the advantages of inumınoflourescense and radioimmunoassay and overcome many of the disadvantages of the other two methods. Enzyme labelled reagents are cheap, easy to prepare and are highly stable so giving a long shelf life, yet yield assays which approach the sensitivity of radionumıassay and which give objective result that can be determined, either visually or with rather simple equipment. In this study, we standardized to determine the antibody with indirect ELISA technique for Gumboro, Newcastle, Avian Encephalomyelitis and lnfectious Bronchitis diseases of the im portant poulty diseases of o ur country. The ELISA and research labotory of our institute will go on to developELJSA test methods for the other important diseases.

Özet

Son yıllarda soluble antijen veya antikorların enzim immunoassay ile solid faz hale getirilip teşhis edilmesinde büyük gelişmeler kaydedilmiştir. lrrımunoassay, diğer immunokimyasal tekniklerin en önemlilerinden biri olup aynı zamanda diğer tekniklerden daha az komplike, daha kolay ve daha çabuktur (21). Antijen ve antikor tayininde oldukca hassas olan ve ELISA olarak bilinen test 1970'lerin başında Engvall ve arkadaşları Van Weemen ile Schurs tarafından geliştirilmiştir( 18). ELISA yöntemi ile antikorların veya antijenlerin saptanmasında ortam ya antikor yada antijen ile kaplanarak duyarlaştırılır ve üzerine konan antijen veya antikor ile reaksiyona girer, üzerine ilave edilen enzim işaretli antiimmunoglobulin ve substrat ile renk değişimi şeklinde substratın parçalanma oranına göre test sonuçlanır ve mikropleytde oluşturulan bu reaksiyonda bir pleyt üzerinde çok sayıda numune işlenebilmektedir. Bu araştırmada şu anda ülkemiz tavukculuğunun önemli hastalıklardan Newcastle, Gumboro, Epidemik tremor ve Enfeksiyöz bronşitis için antikor tayin etmekte kullanılacak olan indirekt ELI SA metodu laboratuvarıınızda standardize edilmiştir.
