Optimizing Pichia Pastoris Cell‐Free Protein Synthesis to Improve Economics

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Cell‐free protein synthesis (CFPS) is a powerful and versatile platform that supports a wide range of applications, from fundamental studies of the genetic code to scalable and rapid protein production. The recently developed Pichia pastoris CFPS combines advantages of both prokaryotic and eukaryotic systems, including a rapid growth rate ...

Tetrazine Ligation in Living Systems: Beyond Fast Kinetics to Effective Bioorthogonality

open access: yesChemistry – A European Journal, EarlyView.
Rapid reaction kinetics (k2) alone do not ensure successful tetrazine ligation in living systems. This review introduces ‘effective orthogonality’—focusing on chemical survival, availability, and encounter—as a practical framework. We highlight how bottlenecks shift from cellular sinks to in vivo delivery limits, offering design strategies for reliable

Microsome Isolation from Tissue

open access: yesBIO-PROTOCOL, 2014
This protocol details the extraction of microsomes from frozen tissue in order to further examine the protein-protein interactions occurring within the endoplasmic reticulum. This protocol was adapted from Abisambra et al. (2013) with modifications made in order to optimize for subsequent use.

Unveiling Hepatic Protein Alterations in Neonatal and Infant Biliary Atresia

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Pediatric populations differ from adults in drug elimination capacity. While current scaling methods account for enzyme and transporter maturation, they overlook comorbidities, such as biliary atresia (BA), a liver disease appearing within the first 2–8 weeks of life that can progress to cirrhosis.

Activation of proestrogens from hops (Humulus lupulus L.) by intestinal microbiota; Conversion of isoxanthohumol into 8-prenylnaringenin [PDF]

open access: yes, 2005
Hop, an essential ingredient in most beers, contains a number of prenylflavonoids, among which 8-prenylnaringenin (8-PN) would be the most potent phytoestrogen currently known. Although a number of health effects are attributed to these compounds, only a
