Streptococcus iniae is a major cause of serious bacterial infections in both fish and human beings. Capsular polysaccharide (CPS) of S. iniae is vital to evade phagocytic clearance of the host and serves as an important protective antigen of S. iniae infection in aquatic animals. The CpsD gene was determined to be highly conservative in capsule polysaccharide operon. Prokaryotic expression of t...

Background and Aims: Influenza A virus of Orthomyxoviridae family is able to create pandemic influenza. Vaccination is the most effective way to prevent influenza virus infection. Matrix protein 2 (M2) is a homotetramer ion channel with 97 amino acids length and highly conserved among influenza viruses and is considered for development of a universal influenza vaccine. Materials and Methods: We...

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...

tetrodotoxin binding activity and a protein of ‫072ف‬ kDa (Agnew et al., 1980). Subsequent purification studies showed that the sodium channel from mammalian brain is a complex of ␣ al., 1982), the tetrodotoxin-binding component of the sodium channel purified from eel electroplax is a single Voltage-gated sodium channels are responsible for the protein of 270 kDa (Miller et al., 1983), and the ...

in biaxially strained p-mosfet with si channel, formation of a parasitic parallel channel due to misalignment of energy bands degrades device performance by increasing off-state current. in this paper a new approach has been introduced to eliminate this parasitic channel by increasing the dopant concentration of virtual substrate up to . using simulation the impact of this method on the parasit...

We have recently demonstrated that the amiloridesensitive Na+ channel in the apical membrane of the renal epithelial cell line, AB, is modulated by the ai-3 subunit of the Gi-3 protein. We also showed that a 700kDa protein complex can be purified from the membranes of A6 epithelia which (a) can reconstitute the amiloride-sensitive Na+ influx in liposomes and planar bilayer membranes and (b) con...
