The surface charge of trypanosomatids of the genus trypanosoma

Memorias do Instituto Oswaldo Cruz, 1990
Cell electrophoresis was used for determionation of the electrophoretic mobility (EPM) of epimastigo and trypamastigote forms of several isolates of Trypanosoma cruzi and some stocks of other members of the Schizotrypanum subgenus, such as T. dionisii, T.

Photoelectrochemical Imaging System for the Mapping of Cell Surface Charges [PDF]

Analytical Chemistry, 2019
The surface charge of cells affects cell signaling, cell metabolic processes, adherence to surfaces, and cell proliferation. Our understanding of the role of membrane charges is limited due to the inability to observe changes without interfering, chemically or physically, with the cell or its membrane.

The role of salt bridges, charge density, and subunit flexibility in determining disassembly routes of protein complexes [PDF]

, 2013
Mass spectrometry can be used to characterize multiprotein complexes, defining their subunit stoichiometry and composition following solution disruption and collision-induced dissociation (CID).

Host glycocalyx captures HIV proximal to the cell surface via oligomannose-GlcNAc glycan-glycan interactions to support viral entry

, 2022
Here, we present ultrastructural analyses showing that incoming HIV are captured near the lymphocyte surface in a virion-glycan-dependent manner. Biophysical analyses show that removal of either virion- or cell-associated N-glycans impairs virus-cell ...

Contributions of Ti-xTa cold spray composite interface to in-vitro cell growth

Smart Materials in Manufacturing, 2023
Surface charge of biomaterials is one of the most influential parameters on regulating the complex processes of cell responses in tissue engineering. This study explores the contributions of xTa (x ​= ​5; 10; 30 in wt%) interface with the Ti as matrix on

Salting the charged surface: pH and salt dependence of protein G B1 stability. [PDF]

, 2006
This study shows significant effects of protein surface charges on stability and these effects are not eliminated by salt screening. The stability for a variant of protein G B1 domain was studied in the pH-range of 1.5-11 at low, 0.15 M, and 2 M salt ...

Positively bound: Remapping of Increased Positive Charge Drives SARS-CoV-2 Spike Evolution to Optimize its Binding to Cell Surface Receptors

, 2022
The SARS-CoV-2 Omicron sub-lineage contains a significant number of mutations in the spike protein relative to earlier SARS-CoV-2 variants. Most notably, these mutations significantly increased the positive charge of the spike protein that is postulated ...

New cationic nanovesicular systems containing lysine-based surfactants for topical administration: Toxicity assessment using representative skin cell lines [PDF]

, 2013
Many strategies for treating diseases require the delivery of drugs into the cell cytoplasm following internalization within endosomal vesicles. Thus, compounds triggered by low pH to disrupt membranes and release endosomal contents into the cytosol are ...

Investigation and electrochemical analysis of SEI layer formation in natural graphite anode formation process in lithium-ion battery

e-Prime: Advances in Electrical Engineering, Electronics and Energy, 2023
The solid electrolyte interface (SEI) layer is a surface film formed by the decomposition of the electrolyte in a lithium-ion battery on the anode surface. A proper understanding of the SEI layer formation process in graphite anodes can provide a broader
