Spectrochim Acta A Mol Biomol Spectrosc. 2021 Dec 02;268:120689. doi: 10.1016/j.saa.2021.120689. Epub 2021 Dec 02.

Herein, we established a fluorescent detection platform for baicalein (Bai) based on copper nanoclusters, which were prepared by using copper sulfate as the precursor, trypsin (Tryp) as the template and hydrazine hydrate as the reducing agent. The entire preparation...

Thiol-Cleavable Biotin for Chemical and Enzymatic Biotinylation and Its Application to Mitochondrial TurboID Proteomics.

Journal of the American Society for Mass Spectrometry

J Am Soc Mass Spectrom. 2021 Sep 01;32(9):2358-2365. doi: 10.1021/jasms.1c00079. Epub 2021 Apr 28.

Protein biotinylation via chemical or enzymatic reactions is often coupled with streptavidin-based enrichment and on-bead digestion in numerous biological applications. However, the popular on-bead digestion method faces major challenges of streptavidin contamination, overwhelming signals from endogenous biotinylated proteins, the...

Cancers (Basel). 2021 Aug 27;13(17). doi: 10.3390/cancers13174349.

Intra-tumor heterogeneity (ITH) results from the coexistence of genetically distinct cancer cell (sub)populations, their phenotypic plasticity, and the presence of heterotypic components of the tumor microenvironment (TME). Here we addressed the potential association between phenotypic ITH revealed by mass...

Gut microbiota and age shape susceptibility to clostridial enteritis in lorikeets under human care.

Animal microbiome

Minich D, Madden C, Navarro MA, Glowacki L, French-Kim K, Chan W, Evans MV, Soares K, Mrofchak R, Madan R, Ballash GA, LaPerle K, Paul S, Vodovotz Y, Uzal FA, Martinez M, Hausmann J, Junge RE, Hale VL.
PMID: 35000619
Anim Microbiome. 2022 Jan 09;4(1):7. doi: 10.1186/s42523-021-00148-7.

BACKGROUND: Enteritis is a common cause of morbidity and mortality in lorikeets that can be challenging to diagnose and treat. In this study, we examine gut microbiota in two lorikeet flocks with enteritis (Columbus Zoo and Aquarium-CZA; Denver Zoo-DZ)....

Effect of trypsin concentration on living SMCC-7721 cells studied by atomic force microscopy.

Journal of microscopy

Microglial cells are the main immune cells of the retina. The primary culture of the retinal microglia is critically important in investigating the cells' properties and behaviors in neurodegenerative and inflammatory retinal disease. Here, we described a modified protocol...

Mimicking LysC Proteolysis by 'Arginine Modification-cum-Trypsin Digestion': Comparison of Bottom-up & Middle-down Proteomic Approaches by ESI Q-TOF MS.

Protein and peptide letters

Pandeswari PB, Chary RN, Kamalanathan AS, Prabhakar S, Sabareesh V.

BACKGROUND: Middle-down (MD) proteomics is an emerging approach for reliable identification of post-translational modifications and isoforms, as this approach focuses on proteolytic peptides containing > 25-30 amino acid residues (a.a.r.), which are longer than typical tryptic peptides. Such longer...

α1-anti-trypsin (A1AT), encoded by SERPINA1, is a neutrophil elastase inhibitor that controls the inflammatory response in the lung. Severe A1AT deficiency increases risk for Chronic Obstructive Pulmonary Disease (COPD), however, the role of A1AT in COPD in non-deficient individuals...
