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...

Quantitative studies of protein abundance rarely span more than a small number of experimental conditions and replicates. In contrast, quantitative studies of transcript abundance often span hundreds of experimental conditions and replicates. This situation exists, in part, because extracting quantitative data from large proteomics datasets is significantly more difficult than reading quantitat...

The advent of sensitive and robust quantitative proteomics techniques has been emerging as a vital tool for deciphering complex biological puzzles that would have been challenging to conventional molecular biology methods. The method here describes the use of two isotope labeling techniques-isobaric tags for relative and absolute quantification (iTRAQ) and redox isotope-coded affinity tags (ICA...

Breast cancer is one of the most frequent and deadly cancers in industrialized countries. The identification of accurate biomarkers that improve the screening, diagnosis, prognostication and prediction of therapeutic response or toxicity, and the identification of novel molecular therapeutic targets are crucial. Today, high-throughput molecular techniques permit investigators to systematically ...

Proteome versus proteins Each organism contains a single genome in virtually all its cells and thus the difference between the numerous cell types within the same organisms are attributed mainly to genetic imprinting, epigenetics, transcriptional and post-transcriptional processes. Thus studying all the protein molecules present in the living system (termed proteomics) at any given time and phy...

Rapidly progressing proteomics techniques have been widely adopted in most areas of biology and medicine. In neurology and neuroscience, many applications of proteomics have involved neurotoxicology and neurometabolism, as well as in the determination of specific proteomic aspects of individual brain areas and body fluids in neurodegeneration. Investigation of brain protein groups in neurodegen...

background : glioblastoma multiforme (gbm) or grade iv astrocytoma is the most common and lethal adult malignant brain tumor. several of the molecular alterations detected in gliomas may have diagnostic and/or prognostic implications, proteomics has been widely applied in various areas of science, ranging from the deciphering of molecular pathogen nests of discuses. method: we extracted protein...

The systematic analysis of biological processes requires an understanding of the quantitative expression patterns of proteins, their interacting partners and their subcellular localization. This information was formerly difficult to accrue as the relative quantification of proteins relied on antibody-based methods and other approaches with low throughput. The advent of soft ionization technique...

Microbial mediated bioremediation has a great potential to effectively restore contaminated environment, but the lack of information about factors regulating the growth and metabolism of various microbial communities in polluted environment often limits its implementation. Newly seeded techniques such as transcriptomics, proteomics and interactomics offer remarkable promise as tools to address ...

Abstract: Introduction: In present situation infertility is one of the chief problem for reproductive couples due to multiple factors including lifestyle. Infertility thought be caused by both male and female in 27 percent cases, with 15 cases being idiopathic. Assisted technologies are used these overcome problems related infertility, but success rate ART appreciated WHO if it reaches 30%. Abo...
