objective: the study of physiological changes in recombinant cell lines provides useful information to improve production performance. in this study, we investigate the effects of an anti-cd33 chimeric igg4 expression on sp2.0 cell growth. methods: variable region genes of light and heavy chains of monoclonal antibody produced by m195 were cloned in pfuse-clig-hk and pfuse-chig-hg4 expression ...
در کمتر از یک دهه، همزمان با به روی کار آمدن نسل های دوم و سوم مخابرات سیار، شرکت های ارائه کننده سرویس مخابرات سلولی به فکر افزودن خدمات مبتنی بر موقعیت به شبکه های مخابرات سیار افتاده اند. طبق تصویب کمیته فدرال مخابرات آمریکا، تمامی شرکت های ارائه کننده خدمات مخابرات سلولی. بایستی مجهز به سیستمی باشند که بتواند موقعیت کاربر را در شبکه در دو سوم موارد (67 درصد) با خطایی کمتر از 100 متر بدست آو...
Background and Objective: Microbial fuel cell (MFC) is a new green technology that uses the catabolic ability of microorganisms to produce bioenergy while simultaneously removing organic matter and other wastewater contaminants. Electrode material is one of the factors affecting the performance of microbial fuel cells. The aim of this study was to investigate the performance of microbial fuel c...
the objective of this research was to investigate the influence of the over-expression of recombinant interferon-g during high cell density cultivation on cellular characteristics of recombinant e. coli. batch and fed-batch culture techniques were employed to grow escherichia coli bl21 for production of human gamma-interferon in pet expression system. final cell densities in batch and fed-batch...
Taguchi L9 orthogonal array was implemented to select optimum values of process parameters and to attain the maximum removal of pollutants and power generation from dairy industry wastewater using double chambered salt bridge microbial fuel cell. The maximum chemical oxygen demand reduction, current, voltage, power, current density and power density in double chambered salt bridge microbial fue...

Seasonal distribution of species composition, cell abundance and biomass of phytoplankton of the Caspian Sea were investigated in 2005. This survey were fulfilled in 6 transects and 26 stations A total of 260 samples were collected during winter to autumn in the southern part of Caspian Sea. Totally, 163 species of phytoplankton were identified (71 species Bacillariophyta, 31 species Chlorophy...
