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 ...

Exploring the potential of ucuúba (Virola surinamensis) seed fat

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Ucuúba (Virola surinamensis) fat is an important income source for Amazonian communities. Local businesses typically process whole seeds for fat extraction; however, seed structural integrity may influence extraction efficiency and fat quality.

Evaluation of nucleotide MALDI-TOF-MS for the identification of Mycobacterium species

Frontiers in Cellular and Infection Microbiology
BackgroundThe accurate identification of the Mycobacterium tuberculosis complex (MTBC) and different nontuberculous mycobacteria (NTM) species is crucial for the timely diagnosis of NTM infections and for reducing poor prognoses.

Copper(0)-mediated radical polymerisation in a self-generating biphasic system [PDF]

, 2013
Herein, we demonstrate the synthesis of well-defined poly(n-alkyl acrylate)s via copper(0)-mediated radical polymerisation in a self-generating biphasic system. During the polymerisation of n-butyl acrylate in DMSO, the polymer phase separates to yield a

High Yield Branched Puromycin Linker Design Enables Efficient cDNA Display and Chemical Modification of Peptides

Biotechnology and Bioengineering, Volume 123, Issue 5, Page 1399-1404, May 2026.
A novel puromycin linker for cDNA display was synthesized via SPAAC reaction. Its functionality was confirmed by recovering intact DNA after selection against EpCAM. The system also enabled the verification of bicyclic peptides during display, demonstrating its utility for constructing and screening structurally complex peptide libraries.

Sensitive and robust MALDI-TOF-MS glycomics analysis enabled by Girard's reagent T on-target derivatization (GTOD) of reducing glycans

Analytica Chimica Acta, 2018
Sensitive glycomics analysis by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) is of great importance but significantly hampered by their low ionization efficiency and labile sialic acid moieties.

Carrier‐free self‐assembled nanomedicine for combination‐therapy of acute myeloid leukemia

BMEMat, EarlyView.
CPDS combines drugs with three different mechanisms of action to achieve a multi‐mechanism combination therapy for AML by directly killing tumor cells and activating anti‐tumor immunity. Abstract As the main acute myeloid leukemia (AML) clinical treatment, the chemotherapy alone cannot meet the clinical therapeutic needs due to the high heterogeneity ...
