Lymphocyte Stimulation by Soluble Subcellular Fractions

Tissue Antigens, 1976
Nuclear material can produce inhibition or stimulation of healthy leucocytes under different experimental conditions. Reactivity could not be produced in cultures using intact nuclei and allogeneic lymphocytes. The effect of nuclear and cytoplasm fractions was compared with that of whole cells on intact healthy lymphocytes.

Steroid dehydrations in porcine subcellular fractions

Steroids, 1970
Abstract Ultracentrifugation separation of porcine ovary and testis into subcellular fractions have shown that a dehydratase enzyme system is localized in the soluble cell fraction (105,000 x g.). It was further demonstrated that ovarian tissue preparations without corpora lutea were enzymatically more active than preparations from corpora lutea ...

Subcellular Fractionation

1997
Abstract Many investigations into the structure and function of cells and tissues require the isolation of a particular membrane or subcellular component (organelle). This book covers all the necessary aspects, from the homogenization of cells via a variety of separation techniques, to the isolation and characterization of peroxisomes ...

Isolation of subcellular fractions

1997
Abstract The aim of subcellular fractionation is to separate cell organelles with as little damage as possible. The first thing to remember is that it will never be possible to separate organelles completely undamaged. In the living cell, most of the cell organelles are attached to cytoskeletal elements and are surrounded by cytosol ...

The subcellular fractionation of the electric organ of Torpedo

Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1966
The acetylcholine-rich electric organ of Torpedo has been submitted to subcellular fractionation in an attempt to isolate nerve endings and synaptic vesicles derived from cholinergic neurones. Fractions containing small vesicles and granules as their only morphologically identifiable components also contained appreciable amounts of bound acetylcholine;

Euglena gracilis Subcellular Fractionation

Subcellular fractionation of Euglena gracilis has been conducted for over 50 years in various forms by numerous research groups. The development of this technique is closely tied to the specific organelle or fraction required for specific purposes.

Subcellular fractionation of mitochondria

1997
Abstract Mitochondria are ubiquitous organelles which are present in the cytoplasm of the vast majority of animal and plant cells. They are also one of the best characterized organelles and indeed were the first membrane-bound particles to be isolated in an intact functional state from living tissues. Together with chloroplasts, they are

The binding of diphenylhydantoin to brain and subcellular fractions

European Journal of Pharmacology, 1971
Abstract The binding of 4- 14 C-diphenylhydantoin (DPH) to homogenates and subcellular fractions of rat brain was studied both in vitro and after in vivo administration. In vitro, small quantities of DPH were bound to brain particles. The binding was reversible.

Subcellular fractionation of cultured glial cells

Journal of Neurobiology, 1971
AbstractWe have studied the subcellular fractionation of a clonal line of glial cells from rat brain. In comparison to rat brain, more of the total protein is collected in the crude nuclear fraction following differential centrifugation. When a crude mitochondrial fraction is prepared and resolved on a density gradient, we find that like brain the ...

The subcellular fractionation of the bovine caudate nucleus

Neurochemical Research, 1982
Two synaptosomal fractions could be obtained from bovine caudate nucleus on sucrose density gradients one of which had a much greater capacity for 'high affinity' choline uptake than the other but comparable amounts of CAT and choline kinase activity.
