A method for isolating and cryopreserving intact mitochondria with improved integrity and functionality

open access: yesBiophysics and Physicobiology
Mitochondria isolated from cells are essential tools in biological research. However, many mitochondria are often damaged during the isolation process.

Isolation and properties of Streptomyces spore membranes [PDF]

open access: yesJournal of Bacteriology, 1986
A simple procedure for the isolation of membranes from Streptomyces spores is described which produces about 12 mg of membrane protein per g of dry weight. The membrane fractions were contaminated by low levels of DNA, RNA, and hexosamines. The functional integrity of the membrane is conserved through the isolation procedure, as evaluated by the ...

Metallic spacers to enhance membrane distillation

open access: yes, 2018
Despite membrane distillation (MD) being well acknowledged as a green technology due to the capability to treat water using waste heat, the efficient use of this heat remains one of the biggest challenge for MD to be cost-effective.

Effect of humic-acid fouling on membrane distillation

open access: yes, 2016
Membrane distillation (MD) can concentrate non-volatile solutes or remove volatiles and dissolved gases from an aqueous feed. A microporous hydrophobic membrane provides a barrier between the hot feed and cold distillate.

Incorporation of barium titanate nanoparticles in piezoelectric PVDF membrane

open access: yes, 2021
The micro-vibration of piezoelectric polyvinylidene fluoride (PVDF) membranes has been shown to mitigate fouling. To improve the desired piezoelectric properties, piezoelectric barium titanate (BaTiO3) nanoparticles (NPs) were incorporated into PVDF ...

Canalicular system reorganization during mouse platelet activation as revealed by 3D ultrastructural analysis

open access: yesPlatelets, 2021
The canalicular system (CS) has been defined as: 1) an inward, invaginated membrane connector that supports entry into and exit from the platelet; 2) a static structure stable during platelet isolation; and 3) the major source of plasma membrane (PM) for

THE ISOLATION AND ANALYSIS OF A MITOCHONDRIAL MEMBRANE FRACTION [PDF]

open access: yesThe Journal of Cell Biology, 1956
PLATE 129 There exists in the literature indication that some mitochondrial enzymes, particularly succinoxidase and cytochrome oxidase, are part of the mitochondrial structure and thus are insoluble when the mitochondria are disrupted. It has further been supposed in particular by Cleland and Slater (1) that this insoluble fraction consists of ...
