phage elisa is a common method to confirm binding of obtained phages from phage display technique to related antigens. enzyme-conjugated antibody directed against the major capsid protein (pviii) or enzyme-conjugated secondary antibody against the primary antibody is used as a detection system in phage elisa. we have suggested to express an acid phosphatase (sapm) enzyme on m13 pix minor coat p...

Molecular Dynamics (MD) simulation and Density Functional Theory (DFT) methods have been used to evaluate the efficiency of four quinoline derivatives on corrosion inhibition in the aqueous phase. Some quantum chemical parameters such as hardness (η), electrophilicity (w), polarizability (a), energy of the highest occupied molecular orbital (EHOMO), energy of th...

although carbon nanotubes (cnt) have been employed as reinforcements in nanocomposites, presence of nano scale defects such as stone-wales and vacancy defects in carbon nanotubes (cnt) weakens the mechanical properties of these materials. in this paper the effects of defects in cnts on nanocomposite elastic behavior are investigated using molecular dynamics. stiffness matrices of cnt and nanoco...

in this work the conduction of ion-water solution through two discrete bundles of armchair carbon and silicon carbide nanotubes, as useful membranes for water desalination, is studied. in order that studies on different types of nanotubes be comparable, the chiral vectors of c and si-c nanotubes are selected as (7,7) and (5,5), respectively, so that    a similar volume of fluid is investigated ...

in this report, we describe a procedure for in-silico design of a novel haloalkane dehalogenase protein that exhibits luciferase property which can be potentially used in biosensor applications. from a pdb blast search, the selected haloalkane dehalogenase (pdb code: 1ede) had a close structural homology with a lucifearse (pdb code: 2psj chain a) sharing an identity of 33%. initially, the amino...
