background permanent antigenic variation of influenza viruses causes a major concern to develop an effective human influenza vaccine. conserved antigens are new vaccine candidates because it is not necessary to match the prepared vaccine with circulating strains. ion channel m2 protein is conserved among all influenza a viruses, allowing the virus to enter host cells. objectives to prepare an e...

background: prediction of interaction sites within the membrane protein complexes using the sequence data is of a great importance, because it would find applications in modification of molecules transport through membrane, signaling pathways and drug targets of many diseases. nevertheless, it has gained little attention from the protein structural bioinformatics community. methods: in this stu...

results the results showed that sensitivity and specificity were respectively 84.12% and 92% for‎ recombinant protein srs3 and 92% and 96% for rsag1. conclusions recombinant proteins srs3 and rsag1 are promising antigens in diagnostic assays for detection of specific antibodies against t. gondii. background infections by the protozoan parasite toxoplasma gondii (t. gondii) are widely prevalent ...

introduction: normal homeostasis system has several inhibitor mechanisms in front of the amplifier’s natural clotting enzyme to prevent fibrin clots in the vessels. the main inhibitors of coagulation pathway are antithrombin (at), protein c and protein s. patients with hereditary deficiency of coagulation inhibitors are susceptible to venous thromboembolism (vte). one of the major clinical mani...

Recombinant protein purification is a kind of sensitive and expensive method in genetics engineering. Genetic manipulation leads to the expression of various proteins; it should be isolated with high purity finally. Differed methods for protein purification are categorized, based on cast, quality, Easy work and side effect of protein. In this article, we are investigating his His-tag protein pu...

circumsporozoite protein (csp) is one of the stage specific antigens, which is used for the development of vaccines and to investigate the genetic diversity in plasmodium falciparum malaria parasite. polymerase chain reaction was used for typing of csp genes on 67 positive falciparum malaria patients from sistan and baluchistan province of iran. three fragments were detected for csp gene. twent...

Synchronization of rumen available protein and energy is one of the conceptual methods to increase the efficiency of utilization of nutrients by the ruminants The concept of synchronization energy and protein was first by Jhonson, Implying that maximum microbial protein synthesis could be achieved by matching the rate of Organic Matter and protein degradation. Synchronization of rumen available...
