A small library of oligoarginine peptides equipped with terminal cysteines was studied with respect to their cell-penetrating properties. The peptides themselves were inactive but gained the ability to enter cells upon extension of their sequence through disulfide bridge formation.

introduction: a noninvasive method of detecting exposure of phosphatidylserine (ps) on the external surface of the plasma membrane such as nuclear imaging could assist the diagnosis and therapy of apoptosis related pathologies. the most studied imaging agent for apoptosis is annexin v so far. because of limitations of annexin v other agents have been introduced such as small peptides and molecu...

Bottom-up proteomics provides often small amounts of highly complex samples that cannot be analysed by direct mass spectrometry (MS). To gain a better insight in the sample composition, liquid chromatography (LC) and (comprehensive) two-dimensional (2D-LC or LC × LC) can coupled to MS. Low-flow separations are attractive for HRMS analysis, but they tend lengthy. In this work, low-flow, online, ...

we have employed a peptide-based antibody generation protocol for producing antibody against human nestin. using a 12-mer synthetic peptide from repetitive region of human nestin protein devoid of any n- or o-glyco-sylation sequences, we generated a mouse monoclonal antibody capable of recognizing human, mouse, bovine, and rat nestin. a wide variety of nestin proteins ranging from 140-250 kda w...

introduction: tobacco smoke is involved in the pathogenesis of several diseases in different body systems. saliva is the first body fluid that confront inhaled cigarette smoke which is injurious to the oral cavity and is associated with several oral diseases and cancer. the aim of our study was to evaluate the influence of smoking on the activity of alpha-amylase in the saliva of healthy smoker...
