In Situ Lipoprotein‐seeking Dye for in Vivo Real‐Time Imaging of Lipid Dysregulation Diseases

Advanced Science, EarlyView.
This study develops lipoprotein‐seeking NIR‐II dyes that specifically bind circulating lipoproteins. These dyes form ultra‐stable complexes with endogenous lipoprotein, enabling real‐time, high‐contrast imaging of fatty liver and atherosclerotic plaques. Tunable binding kinetics allow customized imaging windows.

MALDI-TOF MS: A Microbiological Perspective

, 2022
Mass spectrometry is an analytical technique in which chemical compounds are ionized into charged molecules and ratio of their mass to charge (m/z) is measured (Everley et al., 2008). Matrix-assisted laser desorption ionization (MALDI) is an ionization technique that uses a laser energy absorbing matrix to create ions from large molecules with minimal ...

A Reactive Antagonist Strategy: Cysteine‐Directed Covalent Molecular Glue in Plant Hormone Receptor Regulation

Advanced Science, EarlyView.
The plant hormone jasmonate is perceived by COI1‐JAZ co‐receptors comprising a single F‐box protein COI1 and multiple JAZ repressors with overlapping functions, complicating genetic analysis. We present a reactive antagonist (RA) strategy that selectively promotes COI1 binding to a cysteine‐engineered JAZ variant while blocking wild‐type JAZs, enabling
