this paper reviews recent strategies used for increasing specific yield and productivity in high cell density cultures. high cell density cultures offer an efficient means for the economical production of recombinant proteins. however, there are still some challenges associated with high cell density cultivation (hcdc) techniques. a variety of strategies in several aspects including host design...
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...

Background and purpose: The 50 KDa protein (50 µg) in carboxylic domain of the neurotoxin heavy chain (BoNT/A-Hc) recognizes surface receptors on target neurons and this fragment contains the principle protective antigenic determinants. Recently, this fragment has been used as a recombinant vaccine candidate for botulism. The study aimed to compare the evaluation of BoNT/A-Hc production in fed-...

The objective of this study was to evaluate the apoptotic effects of increasing granulosa cell density and increasing estradiol on relative gene expression associated with apoptosis factors (Bcl-2, Bax and GADD45β) and cell cycle (CCDN-2). For this reason after collecting ovaries of cows from an abattoir, granulosa cells were separated from 4- to 8-mm follicles. Then, viable cells were counted ...
Microfluidics is poised to have an impact on life sciences research. However, current microfluidic methods are not compatible with existing laboratory liquid dispensing and detection infrastructure. This incompatibility is a barrier to adoption of microfluidic systems and calls for improved approaches that will enhance performance and promote acceptance of microfluidic systems in the life scien...
cell lines derived from mammalian are dominant systems for the production of recombinant therapeutic proteins because of their capacity for correct protein folding, assembly and post-translational modification. in the search of an efficient method for the production of a recombinant protein using animal cell culture, we investigated the effects of different treatment including fetal calf serum...
