Chemoenzymatic Synthesis of Well‐Defined α(2,8)‐ and α(2,9)‐Linked Oligosialosides

open access: yesAngewandte Chemie International Edition, EarlyView.
Well‐defined α(2,8)‐ and α(2,9)‐linked oligosialic acids of different lengths can be prepared by employing recombinant bacterial polysialyltransferases in combination with chemically modified CMP‐Neu5Ac derivatives. After transfer, a sialoside is formed bearing an artificial entity, which blocks further glycosylation.

Green Fuel Combustion Synthesis of CeO2 and Ag/CeO2 Nanoparticles for Photocatalytic and Antibacterial Applications

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Silver‐doped cerium oxide nanoparticles (Ag/CeO2 NPs) were synthesized using Ricinus communis seed extract as a bio‐derived fuel in a solution combustion method. The combustion reaction, carried out at 450°C with AgNO3 and (NH4)2[Ce (NO3)6] as metal precursors, produced CeO2 and Ag/CeO2 NPs.

Identification Epitope on VP4 Protein of Senecavirus A Recognized by a Monoclonal Antibody

open access: yesAnimal Research and One Health, EarlyView.
This study aims to identify conserved antigenic epitopes on the SVA VP4 protein using monoclonal antibodies, providing valuable tools for further exploring its functions and developing detection methods. SVA VP4 protein was expressed in Escherichia coli and purified with High‐Affinity Ni‐Charged Resin FF.
