Detergent/surfactant retention during ultrafiltration in the formulation of biotherapeutics

Biotechnology Progress, EarlyView.
Abstract Surfactants like polysorbate (Tween®) are commonly used as excipients in the production of monoclonal antibodies and other recombinant proteins. The retention behavior of these excipients in the final ultrafiltration step can be difficult to predict due to the presence of both monomers and micelles.

Gene \u3cem\u3emdpC\u3c/em\u3e Plays a Regulatory Role in the Methyl-\u3cem\u3etert\u3c/em\u3e-butyl Ether Degradation Pathway of \u3cem\u3eMethylibium petroleiphilum\u3c/em\u3e Strain PM1 [PDF]

, 2015
Among the few bacteria known to utilize methyl tert-butyl ether (MTBE) as a sole carbon source, Methylibium petroleiphilum PM1 is a well-characterized organism with a sequenced genome; however, knowledge of the genetic regulation of its MTBE degradation ...

Synthetic modeling: A cell‐free approach for faster implementation of Raman spectroscopy in cell culture

Biotechnology Progress, EarlyView.
Abstract Monitoring cell culture is crucial for gaining a deeper understanding of processes and ensuring the production of safe and high‐quality products. The capability to measure in real time several parameters of interest can be achieved with Raman spectroscopy.

5‐Aza combined with VPA reprograms human T lineage acute leukemia Jurkat cells into B‐cell‐like cells by epigenetic activation of PAX5

Biotechnology Progress, EarlyView.
Abstract Epigenetic regulation plays an important role in cell fate reprogramming. Here, we found that inhibitors of epigenetic modifiers, including VPA, TSA, and 5‐Aza‐2'‐deoxycytidine, can induce phenotypic transformation from Jurkat cells into B‐cell‐like cells. When Jurkat cells were treated with 5‐Aza combined with VPA, B cell and stem cell marker

N‐1 semi‐continuous transient perfusion in shake flask for ultra‐high density seeding of CHO cell cultures in benchtop bioreactors

Biotechnology Progress, EarlyView.
Abstract One strategy to enhance the production of biological therapeutics is using transient perfusion in the preculture (N‐1 stage) to seed the production culture (N stage) at ultra‐high cell densities (>10 x 106 viable cells/mL). This very high seeding density improves cell culture performance by shortening the timeline and/or achieving higher final

Comparison of Streptococcus pneumoniae isolates occurring in optochin-susceptible and optochin-resistant variants by analyzing whole-genome sequencing data

Microbiology Spectrum
The paper presents the study of a set of isolates of Streptococcus pneumoniae, which comprised two heterogeneous subpopulations, one of which was susceptible and the other resistant to optochin.
