Mammalian plasma membranes

Nature, 1975
1975 is the fiftieth anniversary of the proposal, by Gorter and Grendel, that biological membranes are based on a lipid bilayer. Now well established, this proposal, like the DNA double helix, was a major breakthrough in molecular cell biology. Here we discuss current concepts about the molecular composition, organisation and behaviour of the plasma ...

Carcinogenesis and the plasma membrane

Medical Hypotheses, 1999
Presented is a two-stage hypothesis of carcinogenesis based on: (1) plasma membrane defects that produce abnormal electron and proton efflux; and (2) electrical uncoupling of cells through loss of intercellular communication. These changes can be induced by a wide variety of stimuli including chemical carcinogens, oncoviruses, inherited and/or acquired

Isolation of Plasma Membrane and Plasma Membrane Microdomains

2016
The plasma membrane surrounds the cytoplasm of a cell and functions as a barrier to separate the intracellular compartment from the extracellular environment. Protein and lipid components distribute nonuniformly and the components form clusters with various functions in the plasma membrane.

Dehydrogenases of the Plasma Membrane

1979
Oxidation-reduction reactions are widespread in biological systems and are basic to life processes and cellular metabolism. Nicotinamide-nucleotide-linked electron transport is generally part of a complex chain or array of carriers linked both structurally and functionally to cellular membranes. Some of the carriers may be loosely bound to the membrane

Sperm plasma membrane receptors for the porcine oocyte plasma membrane

Zygote, 1998
In vitro fertilisation (IVF) was used to assess the ability of solubilised sperm plasma membrane (PM) proteins to inhibit the interaction of intact gametes. This is a first step before evaluating the ability of individual isolated proteins to competitively inhibit sperm-oocyte interaction as part of the process of studying the molecular events of ...

Isolation of the plasma membrane

1986
Publisher Summary Plasma membranes of plants are purified by using either sucrose gradients or aqueous two-phase system consisting of Dextran T 500 and polyethyleneglycol 3350. The sucrose gradient separation takes advantage of the different sizes and densities of the various membranes in the cell, whereas the two-phase polymer system takes advantage
