Data for engineering lipid metabolism of Chinese hamster ovary (CHO) cells for enhanced recombinant protein production.

The data presented in this article relates to the manuscript entitled 'Engineering Chinese hamster ovary cell lipid metabolism results in an expanded and enhanced ER recombinant biotherapeutic protein production', published in the journal Metabolic Engineering [1].  In the article here, we present data check excess of modifying lipid metabolism and SREBF1 SCD1 gene in CHO cells by densitometry of Western E.coli Recombinant Proteins  Blot and by using mass spectrometry to investigate the impact on a particular lipid species. We also immunofluorescence data present on the SCD1 protein levels and SREBF1 excess.  Data growth profile during the batch culture and control CHO cells CHO cells engineered to overexpress SCD1 and SREBF1 during batch culture are also reported. Finally, we report data on the model results secretion of recombinant proteins produced from the control, SCD1 or SREBF1 engineered cells using a transient expression system. Alanine Substitution Cross-React in...

Optimization of recombinant Zika virus NS1 protein secretion from HEK293 cells.

Sensitive, accurate and cost-effective diagnostic tests are needed to detect the Zika virus (ZIKV) infection. Nonstructural 1 (NS1) glycoprotein is an excellent diagnostic marker because it was released in a hexameric conformation of the infected cells into the bloodstream of patients in the early course of infection. We established a stable system of his rZNS1-expression in HEK293 cells through lentiviral transduction.  New optimization approach to improve Cavia Recombinant Proteins  his rZNS1 secretion of proteins in mammalian expression systems is achieved through incubation of 50 nM rapamycin followed by incubation in serum-free media for 9 days, attaining the protein from ~ 10 mg / l of culture medium.  His rZNS1 purified hexamer recognized by anti-NS1 antibodies in serum ZIKV patients, and demonstrated the ability to induce a humoral response in mice immunized. recombinant proteins obtained are reliable biological tool that can potentially be applied in the develop...

A Simple Method for the Design and Development of Flavivirus NS1 Recombinant Proteins Using an In Silico Approach.

Even in countries that do not currently face a flavivirus epidemic, the spread of mosquito flaviviruses prize increased public threat, due to climate change, international travel, and other factors. Many of these countries do not have the resources (strain of the virus, clinical specimens, etc.) necessary for research that can help overcome Canine Recombinant Proteins  the threat imposed by flaviviruses, and therefore, an alternative approach is needed.  Using in silico approach to the global database, we aim to design and develop a recombinant flavivirus NS1 protein with consideration of antigenic variation. NS1 gene were analyzed in this study included a total of 6823 sequences, of the dengue virus (DENV), Japanese encephalitis virus (JEV), West Nile virus (WNV), Zika virus (ZIKV), and yellow fever virus (YKV).  We extracted and analyzed 316 DENV NS1 sequence type (ST), 59 ST JEV, WNV ST 75, 30 YFV ST and 43 ST ZIKV using a simple algorithm based on phylogenetic analys...

Mycobacterium tuberculosis PE31 (Rv3477) Attenuates Host Cell Apoptosis and Promotes Recombinant M. smegmatis Intracellular Survival via Up-regulating GTPase Guanylate Binding Protein-1.

Mycobacterium (M.) tuberculosis acidic (PE) proline-glutamic subfamily proteins associate with virulence, pathogenesis and host-immune modulation. While the function of most of the family members have not been explored. Here, we explore the function of "PE only" subfamily members PE31 (Rv3477) in virulence and host-pathogen interactions. Viral Recombinant Proteins We have stated M. tuberculosis PE31 in non-pathogenic Mycobacterium smegmatis strain (Ms_PE31) and shows that a significant change aspects of the cell PE31 features including colony morphology and biofilm formation. PE31 expressing M. smegmatis showed more resistant to low pH, diamide, H2O2 and surface stress. In addition, the intracellular survival Ms_PE31 showed higher macrophage THP-1 cells. Ms_PE31 significantly down-regulated the production of IL-12p40 and IL-6, while up-regulate the production of IL-10 in macrophages.  Ms_PE31 also induced the expression of guanylate-binding protein-1 (GBP-1) in macrophages. ...

Cost analysis based on bioreactor cultivation conditions: Production of a soluble recombinant protein using Escherichia coli BL21(DE3).

The impact of the strategy on the cultivation of recombinant protein production costs are very important to define cost-effective bioreactor operating conditions. This paper presents a methodology to assess and compare the impact of costs associated with utilities and media composition, using the simple design equations and data can be accessed. Data from batch bioreactor culture Parasite Recombinant Proteins  is used as a case study involving the production of pneumococcal surface protein A, soluble recombinant proteins, employing E. coli BL21 (DE3). aquaculture strategy and the corresponding cost of the process include a variety of operating conditions, including different media, inducers, and temperature.  Core costs associated with the media and cooling. When the price of peptone is above the threshold value of US $ 30 / kg, the medium is defined to be the best choice. IPTG and temperatures around 32 ° C led to a culture that is shorter and lower production costs PspA4Pro...

In Vivo Removal of N-Terminal Fusion Domains From Recombinant Target Proteins Produced in Nicotiana benthamiana.

Plants show great potential for the production of recombinant proteins in a cost-effective manner. Many strategies have therefore been used to express high levels of recombinant proteins in plants. Although foreign domains fused with the target protein expression or as a high-affinity tag for purification, retention of foreign domain to its target protein may not be desirable, especially for biomedical purposes. Thus, their removal is often important at a certain time point after translation.  Here, we develop new strategies Monkey Recombinant Proteins  to produce a target protein without foreign domain. It engages in vivo elimination of foreign domains fused to the N-terminus with a modifier (SUMO) domain / SUMO-specific protease systems associated ubiquitin-small.  This strategy successfully tested by generating a recombinant gene, beep: p38: bdSUMO: His: hLIF, which produce human leukemia inhibitory factor (hLIF) fused to p38, Turnip crinkle virus coat protein; the inc...
