Downstream Workflows for Intermediate Purification of Lentiviral Vectors Using Tangential Flow Filtration and AEX Membrane Chromatography

Engineering in Life Sciences, Volume 25, Issue 10, October 2025.
ABSTRACT The growing demand for large quantities of high‐purity lentiviral vectors (LVs) has driven the development of scalable, cost‐effective purification strategies. Membrane chromatography is particularly well‐suited for purifying large biological entities like LVs due to its low mass transfer resistance and minimal back pressure.

Alistipes senegalensis is Critically Involved in Gut Barrier Repair Mediated by Panax Ginseng Neutral Polysaccharides in Aged Mice

Advanced Science, Volume 12, Issue 36, September 25, 2025.
An integral functional axis through which GPN and functional metabolites of Alistipes senegalensis can hydrolyze tryptophan into indoles. Furthermore, the Alistipes senegalensis‐indole‐AhR pathway is found to be associated with increased expression of tight junction‐associated proteins and activation of gut stem cells.

Development of a Triticale‐Based Amylolytic Biocatalyst for Starch Hydrolysis With Applications in Brewing Wort Sugar Enhancement

Food Bioengineering, Volume 4, Issue 3, Page 305-317, September 2025.
Co‐immobilization of α‐amylase and β‐amylase from triticale malt in cross‐linked gelatin improved kinetic parameters and achieved over 100% immobilization efficiency. The triticale malt‐based α‐amylase and β‐amylase biocatalyst enhanced reducing sugar release in barley wort by 11.8 g/L in the first cycle and retained 5.8 g/L after five reuse cycles ...
