Comparison of Two Different Methods for the Extraction of Outer Membrane Vesicles from the Bordetella pertussis as a Vaccine Candidate [PDF]
Archives of Razi Institute, 2021 Despite the availability of a vaccine, pertussis is still a worldwide health problem. Outer membrane vesicles (OMVs) in gram-negative bacteria can stimulate the immune system due to several outer membrane proteins and are very good candidates in vaccine ...

Reincarnation of the Analytical Ultracentrifuge: Emerging Opportunities for Nanomedicine.
Analytical Chemistry, 2021 The analytical ultracentrifuge (AUC) and the modern field of analytical ultracentrifugation found its inception approximately a century ago. We highlight the scope of its major experimental opportunities as a transport-based method, contemporary and up ...

A Miniature Sucrose Gradient for Polysome Profiling
Bio-Protocol, 2023 Polysome profiling by sucrose density gradient centrifugation is commonly used to study the overall degree of translation (messenger RNA to protein synthesis). Traditionally, the method begins with synthesis of a 5–10 mL sucrose gradient onto which 0.5–1

Journal of Analytical Methods in Chemistry, 2020 Introduction. As a common interferer in clinical chemistry, lipemic specimens could be a source of significant analytical errors. Ultracentrifugation has been by far the only reliable, but an unavailable and expensive, method to eliminate the lipemic ...
