While surfactants are commonly used in preparing protein samples, their presence in a protein sample can potentially affect the enzymatic digestion process and the subsequent analysis of theExpand
CD8Tc1 and Tc2 cells secrete distinct cytokine patterns in vitro and in vivo but induce similar inflammatory reactions.
Naive CD8 T cells, similar to CD4 T cells, can differentiate into at least two subsets of cytolytic effector cells with distinct cytokine patterns: T cytotoxic-1 (Tc1) cells secrete a Th1-likeExpand
Comparison of SDS‐ and methanol‐assisted protein solubilization and digestion methods for Escherichia coli membrane proteome analysis by 2‐D LC‐MS/MS
Both organic solvent and surfactant have been used for dissolving membrane proteins for shotgun proteomics. In this work, two methods of protein solubilization, namely using 60% methanol or 1% SDS,Expand
IL-10 inhibits cytokine production, vascular leakage, and swelling during T helper 1 cell-induced delayed-type hypersensitivity.
The Th1 group of cytokines (IL-2, IFN-gamma, and lymphotoxin (LT)) is usually associated with delayed-type hypersensitivity (DTH), whereas Th2 cytokines (IL-4, IL-5, IL-6, and IL-10) often accompanyExpand

Tear proteome profiling may generate useful information for the understanding of the interaction between an eye and its contacting objects, such as a contact lens or a lens implant. This is importantExpand
Open tubular immobilized metal ion affinity chromatography combined with MALDI MS and MS/MS for identification of protein phosphorylation sites.
Protein phosphorylation is one of the most important known posttranslational modifications. Tandem mass spectrometry has become an important tool for mapping out the phosphorylation sites. However,Expand
MyCompoundID: using an evidence-based metabolome library for metabolite identification.
Identification of unknown metabolites is a major challenge in metabolomics. Without the identities of the metabolites, the metabolome data generated from a biological sample cannot be readily linkedExpand

The envelope of Escherichia coli is a complex organelle composed of the outer membrane, periplasm-peptidoglycan layer and cytoplasmic membrane. Each compartment has a unique complement of proteins,Expand
Pulmonary toxicity and metabolic activation of tetrandrine in CD-1 mice.
Tetrandrine, a bisbenzylisoquinoline alkaloid, has demonstrated promising pharmacologic activities. The alkaloid has a great potential for clinical use, so a careful, thorough toxicity evaluation ofExpand
