Methanol extracts of lesser chickweed from Egypt showed the strongest phenolic content, antioxidant scavenging, and antimicrobial activity in new laboratory screening, with molecular docking suggesting which compounds deserve further study.
By Vivienne Raper, PhD A new technique combining two forms of spectrometry could help biopharmaceutical companies improve their choice of formulation buffer for antibody manufacturing by revealing how molecular forms and three-dimensional shapes of complex biologics respond to their environment.
The work focuses on building a workflow that can separate glycol contaminants from the many non-volatile ingredients found in syrups. By coupling chromatographic separation with mass spectral identification, the method aims to distinguish target analytes even when the sample matrix…
HPLC is a powerful tool for evaluating research-compound purity, but its results must be interpreted within the limits of the method.
