Western Blot tekniği, herhangi bir örnekten istenen tek proteini özgün şekilde saptamak için moleküler biyolojide kullanılan eski ve güvenilir yöntemdir. Proteinlerin uyaranlara karşı verdiği yanıtların araştırılmasında, protein ifadesinin var-yok ya da artmış-azalmış olarak değerlendirilmesinde, hücre spesifik izoformlarının belirlenmesinde, genetik hastalıkların ortaya çıkışından sorumlu prot...

it is well accepted that in experimental model of leishmania major infection, balb/c mice mount a th2 response and produce igg1 predominantly whereas c57bl/6mice enhance th1 response with the biased production of igg2a antibodies. therefore, screening for parasite antigens on the basis of reactivity with sera from infected susceptible or resistant mice might be used for the identification of th...

cystic fibrosis is an autosomal recessive disease caused by a wide spectrum of mutations in the gene encoding for the cystic fibrosis transmembrane conductance regulator protein. these mutations that correlate with different phenotypes, vary in their frequency and distribution in different populations. in this study missense mutation r117h that associated with the different clinical symptoms wa...

background and aims: hiv is spreading rapidly among people word wide. infection with this virus leads to immune suppression and finally acquired immune deficiency syndrome (aids).early hiv detection is depended on antibody screening against virus by enzyme linked immunosorbent assay (elisa).some confirmatory tests such as western blot and recombinant immunobloting assay (riba), are used to veri...

serological methods are commonly used methods for detection of viruses. preparation of pure viral antigens is a crucial step in production of antibodies required for serological studies. in this research the gene encoding coat protein of a beet western yellows virus (bwyv) isolate from iran was amplified by pcr and was ligated into a bacterial expression vector (pet26b) to obtain pet-bwyv-cp cl...

citrus tristeza virus (ctv) is among the most destructive pathogens of citrus and causes substantial economic losses in citrus-growing industry worldwide. considering recent distribution of this pathogen and its capability of transmission by existing aphid vectors in iran, detection of this virus is enforceable for controlling the damage caused by this pathogen in iran, as one of the major citr...
