the aim of this study was to clone the serine alkaline protease-encoding gene from bacillus subtilis 168. this protease, which can have many applications especially in detergent, may be industrially an important enzyme. for the amplification of the gene, pcr was performed with a pair of primers specifically designed for this purpose. electrophoresis of the pcr product showed the expected band o...
The pLE2SCX vector was developed for the stable expression of exogenous genes in the protozoan parasite Leishmania. The pLE2SCX construct contains three independent selection markers: herpes simplex virus thymidine kinase (HSV-TK), cytosine deaminase (CD) and streptothericin acetyltransferase gene (sat) in multiple cloning site, flanking by 5’ and 3’ untranslated regions of the previously clone...
Background & Aims: Salmonella Typhimurium is a negative-gram, non-spore, free capsule, moving bacteria with Trish Perry flagella. Salmonella is the most common cause of food poisoning. The ability to enter and survive in host cells is the condition for pathogenic Salmonella species. Proteins of invasive Salmonella are transferred to the host cells by bacteria. This study was performed for gener...
Background and Objective: Breast cancer is the fifth common cause of death in the world and is considered as the leading cause of cancer related death among females. HER2 is a surface antigen which is overexpressed in 30% of breast cancer cases. The aim of this study was cloning of HER2 receptor gene in pCDNA3.1Hygro+ expression vector, expression of this protein in LL2 eukaryotic cell line and...
Background and Aims: DNA cloning, sub-cloning and site directed mutagenesis are the most common strategies in nearly all projects of recombinant protein production. The classical method of restriction site cloning is unsatisfactory due to the need for supply of restriction enzymes and the inefficiency of the digestion reaction. Many new methods, including recombinatorial cloning and ligation in...

Background and purpose: Polymerase chain reaction (PÇR) is a rather quick and accurate method employed for gene detection and isolation. Primer designing is an important issue in this technique and plays a critical role in considering both the genome properties and cloning of the isolated genes. Streptomycin antibiotic is produced by Streptomyces griseus using str gene cluster with more than 25...
Toxoplasma gondii contain various immunogenic antigens. The most important Toxoplasma antigens are somatic and excreted/secreted antigens. Rhoptry proteins are known as excreted/secreted antigens. These antigens have been proposed as a vaccine candidate against toxoplasmosis. The main objective of the present work was cloning rhoptry protein1 (ROP1) Gene of Toxoplasma gondii (RH) in a cloning...
