abstract east azarbaijan province is one of the most important areas for poplar production and has the highest suitability of poplar plantation in iran. three species of poplar trees included populus alba, p. nigra and p. x. euramericana are planted and usually attacked by different pests in this province. melasoma populi l., archips rosana (l.) and pemphigus filaginis are some of important pes...

GalAGs (galactosaminoglycans) are one subset of the GAG (glycosaminoglycan) family of chemically heterogeneous polysaccharides that are involved in a wide range of biological processes. These complex biomacromolecules are believed to be responsible for the inhibition of nerve regeneration following injury to the central nervous system. The enzymic degradation of GAG chains in damaged nervous ti...

Variants of the prototype Murray Valley encephalitis virus (MVE-1-51) were selected by serial plaque purification and amplification in monkey kidney (Vero) cells. Four clones (C1-C4) at passage levels two and nine (P2 and P9) were examined in 21-day-old Swiss outbred mice for neuroinvasiveness (assessed from LD50 values after intraperitoneal inoculation) and neurovirulence (LD50 values after in...

The mAb lan3-6 recognizes a cytosolic antigen which is selectively expressed in the growth cones and axons of a small subset of peripheral sensory neurons fasciculating in a single tract common to all hirudinid leeches. We have used this antibody to clone a novel EF-hand calcium-binding protein, calsensin, by screening an expression vector library. A full-length clone of 1.1 kb identified by th...

PURPOSE Monoclonal antibodies and related conjugates are key reagents used in biomedical researches as well as, in treatment, purification and diagnosis of infectious and non- infectious diseases. METHODS Balb/c mice were immunized with purified human IgG. Spleen cells of the most immune mouse were fused with SP2/0 in the presence of Poly Ethylene Glycol (PEG). Supernatant of hybridoma cells ...

Most current research on human brain tumors is focused on the molecular and cellular analysis of the bulk tumor mass. However, there is overwhelming evidence in some malignancies that the tumor clone is heterogeneous with respect to proliferation and differentiation. In human leukemia, the tumor clone is organized as a hierarchy that originates from rare leukemic stem cells that possess extensi...

BACKGROUND A superior Green Fluorescent Protein (GFP) mutant, known as superfolder GFP (sfGFP), is more soluble, faster folding, and is the brightest of the known GFP mutants. This study aimed to create a codon-adapted sfGFP tag (TtsfGFP) for simultaneous protein localization and affinity purification in Tetrahymena thermophila. RESULTS In vivo fluorescence spectroscopic analyses of clones ca...

The protein productions strategies are crucial towards the development of application based research and elucidating the novel purification strategies for industrial production. Currently, there are few innovative avenues are studies for cloning, upstream, and purification through efficient bioprocess development. Such strategies are beneficial for industries as well as proven to be vital for e...

6.1 Overview In Chapter 5 a new universal cloning strategy for the production of specifically designed surface-active PAA’s was introduced. Here, we apply this strategy to the production of a unique surface-active PAA designed to form brush layers on aluminum oxide surfaces. This chapter discusses the procedure taken in assembling the gene encoding for a PAA diblock consisting of a long zwitter...
