These methods depend on the quality and purity of antibody used in immunodetection. Availability of purified antigen, free from plant debris, will lead to produce highly purified antibody. The purified antibody in immunodetection methods will increase the sensitivity, specificity and accuracy for virus detection. Cucumber Mosaic Virus (CMV) has worldwide distribution and wide host range. Therefore the presence of highly purified antibody will help us in rapid CMV-immunodetection. The main goal in this study is to compare serologically the sensitivity and accuracy of serological methods by using two antibodies. The first, raised against the recombinant expressed coat protein (Ab/CP) and the second produced against the viral particals (Ab/V) of Ban-CMV. ELISA, Dot blot analysis and Western blotting were used as immunodetection methods. In the three serological methods, both IgGs were able to recognize the presence of Ban-CMV in the tested samples at a dilution I mg/ml. However, Western and dot blot analysis were faster in detection of Ban-CMV than ELISA using Ab/CP.","PeriodicalId":31811,"journal":{"name":"Egyptian Journal of Genetics and Cytology","volume":"9 1","pages":"259-267"},"PeriodicalIF":0.0,"publicationDate":"2013-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68478277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The toxic effects of gentamicin were assessed in term of the changes in relative organs weights in addition the genetic variation in DNA-RAPD profiles in both liver and spleen. Results showed that no significant differences were found between the negative control and all of tested groups for relative liver weights, while the group fed on parsley oil recorded the highest value of relative spleen weight which did not differ than negative control group. For RAPD profiles, the differences in RAPD patterns refer to band intensity, loss of normal bands and appearance of new bands as compared with the negative control group. All these differences were well represented in the patterns produced in gentamicin group as well as all rat groups fed on parsley. Changes in bands intensity which were major event increased by gentamicin effect, were decreased in all groups fed on parsley forms except the group fed on seeds (for liver DNA) and the group fed on parsley leaves extract (for spleen DNA) were increased. Parsley leaves and oil (for liver) and parsley oil (for spleen) exhibited the best effect in reducing the increase in band intensity. All forms of parsley caused a decrease in the genomic template stability (%) values compared to gentamicin group. The major decrease was for leaves extract with regard to liver DNA and for seeds with regard to spleen DNA. Results of this study demonstrated the genotoxic effects of gentamicin on rat's liver and spleen. In addition, the results revealed that parsley oil may be the effective form in reducing gentamicin genotoxic effect followed by parsley fresh leaves.","PeriodicalId":31811,"journal":{"name":"Egyptian Journal of Genetics and Cytology","volume":"42 1","pages":"379-392"},"PeriodicalIF":0.0,"publicationDate":"2013-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68476860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By applying RAPD analysis, 116 bands were obtained from seven primers with 87.07% polymorphism. The UPGMA dendrogram based on genetic distance segregated the five genotypes into two main clusters. Both isozymes and RAPD markers separated teosinte into the first cluster, whereas the four maize types were grouped together in the seconds cluster. Dent and flint types were much close to each other with high similarity indices; 0.842 and 0.792 based on peroxidase and esterase isozymes, respectively.

Seven isozyme systems including Acp (acid phosphatase), Adh (alchol dehydrogenase), α- and β-Est (esterases), Ao (Aldehyde oxidase), Mdh (malate dehydrogenase) and Prx (peroxidase) successfully indicated genetic variability estimated as 70% polymorphism discriminating between seven Cucurbitaceae species.
