Rhipicephalus (Boophilus) annulatus is an important tick, which can transmit parasites and bacteria to cattle. It can also cause hides damage, growth reduction and sometimes paralysis. So, the tick infestation can be regarded as a major problem in the livestock industry. Different control methods including the chemical ones are used to fight ticks, but because of developing resistance to chemical treatments, researchers try to find some immunogenic proteins for vaccine production. Investigating these tick proteins could be an important step in the identification of biological molecules for the purpose of developing control strategies. The aims of present study were to evaluate and analyze Boophilus annulatus larval extract proteins by 2- dimensional gel electrophoresis patterns (proteomic profiling) and identification of some its immunogenic proteins by two dimensional immunoblotting and MALDI TOF/TOF mass spectrometry referred to as Mazandaran strains. The steps followed here were: tick preparation and culture, 1-D electrophoresis, and then 2-D electrophoresis, Western blotting and Mass spectrometry and then Mass data were analyzed by Mascot software. Analysis of the produced 2D image identified approximately 80 protein spots with different Molecular weight and PI by Coomassi blue staining. Based on immunogenicity (through Western blotting) and high concentration, 10 protein spots (between 14 and 97 kDa) candidates for MALDI TOF and MALDI TOF - TOF MS. Among the 10 proteins spots, Vitellogenin, Vitellogenin-2 precursor, tropomyosin, hypotethical protein ISCW001652 were identified proteins with immunogenic properties. Also, quantification analysis showed some proteins had more quantity in soluble larvae protein extract and some such as vitellogenin had some isoforms. The results of this study could be a preliminary step towards selecting proteins candidated to develop vaccines against ticks.
