Background: Rabies virus (RABV) is a deadly neurotropic virus that causes the disease of rabies in humans and animals. L protein is one of the large structural protein of rabies virus, which displays multiple enzymatic activities, and is required for viral transcription and replication. Objectives: A truncated L protein of Rabies virus is being cloned, expressed and purified to produce relevant...

Antifungal agents are causing different problems in the agriculture industry. Plants are using various defense mechanisms for resistance against fungal pathogens. Some examples of these mechanisms are making physical barriers, producing chemical components and pathogenesis-related proteins such as lipid transfer protein (LTP) and Osmotin which can inhibit the growth of fungi at micro-molar conc...

Background: Bovine follicle stimulating hormone (bFSH) belongs to the family of glycoprotein hormones that are released from the pituitary gland or the placenta. This hormone is a heterodimer consisting of common α- and specific β-subunit. Bovine FSH is used for reproductive technology such as superovulation in farm animals and polycystic ovary syndrome treatment. Also this hormone is produced ...

objective: the secreted aspartic proteinases (sap2) of candida albicans has prominent role on candida adherence, invasion, and pathogenicity. the aim of this study was cloning, expression and characterizing of sap2 enzyme. also in this study for the first time, the expression system p. pasturis was used for expressing the recombinant protein. materials and methods: c. albicans sap2 gene was am...

objectives: in present study we aimed to clone the lux i gene encoding n-acyl-homoserine synthase detected in biofilm forming clinical isolates of acinetobacter baumannii and study its expression in escherichia coli transformants. materials and methods: four a. baumannii hospital strains which demonstrated strong biofilm activity were selected in this investigation. the presence of lux i gene w...

PURPOSE To evaluate the capacity of a replication-defective adenoviral vector to transport retrogradely from the superior colliculus to the nuclei of retinal ganglion cells and to express in these cells vector-encoded transgene. METHODS A replication-deficient adenovirus encoding an expression cassette for the Escherichia coli gene lacZ was injected into the right superior colliculus of mice....

background: the aim of present study was to evaluate the protective efficacy of live recombinant l. tarentolae expressing kmp11-ntgp96-gfp fusion as candidates for live engineered recombinant vaccine against visceral leishmaniasis in balb/c mice. methods: kmp-11 and nt-gp96 genes cloned into the pjet1.2/blunt cloning vector and then into pegfp-n1 expression vector. the kmp-11, nt-gp96 and gfp f...

DNA polymerase gene from Thermus aquaticus strain YT1 was amplified using VENTTM DNA po-lymerase and cloned under the control of X.PR promoter and expression was induced by a shift in tern perature. The culture was then sonicated, and after centrifugation the lysate was treated with poly‌ethyleneimine followed by a salting-out step. Finally the protein was precipitated with ammonium sulfate and...
