Astrobiology, 2002
Organic compounds are synthesized in the interstellar medium and can be delivered to planetary surfaces such as the early Earth, where they mix with endogenous species. Some of these compounds are amphiphilic, having polar and nonpolar groups on the same molecule.

Permeabilization of Cell Membranes
2009In order to detect intracellular antigens, cells must first be permeabilized especially after fixation with cross-linking agents such as formaldehyde and glutaraldehyde. Permeabilization provides access to intracellular or intraorganellar antigens. Two general types of reagents are commonly used: organic solvents, such as methanol and acetone, and ...

Cell membrane‐mediated cytolysis by membranes from noncytolytic cells
European Journal of Immunology, 1978AbstractCytolysis was obtained with plasma membrane fractions prepared not only from cytolytic T cells, but also from nonimmune lymphoid cells and, moreover, from cell lines of nonlymphoid origin displaying no lytic ability. Furthermore, no relationship exists between the genetic specificity of T cell‐mediated cytolysis and the activity of membrane ...

Affinity chromatography of cells and cell membranes
Journal of Chromatography A, 1980This article attempts to introduce the concept of cellular affinity chromatography as it departs from molecular affinity chromatography. Special emphasis is placed on the selectio of a solid support as well as on the role of lectins as affinity ligands.

The cell membrane and membrane proteins
2018This chapter talks about biological membranes that have a lipid bilayer structure made up of a variety of different lipids held together by noncovalent bonds. It shows that lipids are arranged with their hydrophobic tails pointing to the middle of the bilayer and their hydrophilic sections to the outside.

Electropermeabilization of the Cell Membrane
2014Membrane electropermeabilization is the observation that the permeability of a cell membrane can be transiently increased when a micro-millisecond external electric field pulse is applied on a cell suspension or on a tissue. Applicative aspects for the transfer of foreign molecules (macromolecules) into the cytoplasm are routinely used.

Water Channels In Cell Membranes
Annual Review of Physiology, 1992Although water moves through the lipid domain of all biological membranes, there is strong evidence that facilitated or channel-mediated water transport exists in a number of cell plasma membranes and intracellular vesicles (l0, 37). The kidney proximal tubule contains water transporters in the cell apical and basolateral plasma membranes to facilitate
