objective: in this study, two conserved genes (m1 and np) of influenza virus were expressed in a bicistronic vector in order to develop a universal gene based vaccine. materials and methods: plasmids m1-pires2-egfp, pires2-np were constructed by cloning the pcr products of m1 and np genes which were amplified from the a/peurto rico/8/34 (h1n1) influenza virus strain into the plasmid expression...

conclusions the results of the present study will increase our knowledge about molecular cloning and expression of the l. infantum kmp-11 gene, and this may be used as an effective target for controlling visceral leishmaniasis. results the kmp-11 gene was successfully subcloned in pcdna3 as a eukaryotic expression vector. recombinant kmp-11 protein was confirmed by the reverse transcriptase pol...

Background: Human epidermal growth factor receptor 2 (HER2) is over-expressed in breast, ovarian, gastric, and prostate cancers used as a tumor marker the diagnosis of cancer. Monoclonal antibodies have been diagnostic therapeutic tool against HER2. Because difficulties associated with stability complexity construct high cost antibody production, we aimed to investigate, cloning, expression HER...

Bacterial-based systems as live vectors for the delivery of heterologous antigens offer a number of advantages as vaccination strategies. Developments in genetic engineering have given Gram-positive lacticacid bacteria (LAB) the advantage of being used as a host expression system for antigen delivery to inducethe immune response. A fragment containing the full length of the “eprA1” ...

background and objectives: during past decades hansenula polymorpha has attracted global attention for the expression of recombinant proteins due to its high growth rate, minimal nutritional porequirements and use of methanol as a low cost inducer. materials and methods: the corresponding nucleotide sequences for the expression of heterologous genes in hansenula poylmorpha were extracted and as...

Alcanivorax borkumensis is a marine bacterium that has ability to grow on limited substrates that mainly is alkanes. The ability to use wide range of hydrocarbons is advantage of this bacterium to other marine community bacteria. A. borkumensis have two genetic systems for alkane biodegradation. The First system is alkane hydroxylase (alk-B1and alk-B2) and the second system is...
