One-step subcellular fractionation of rat liver tissue using a Nycodenz density gradient prepared by freezing-thawing and two-dimensional sodium dodecyl sulfate electrophoresis profiles of the main fraction of organelles.

One-step subcellular fractionation of rat liver tissue using a Nycodenz density gradient prepared by freezing-thawing and two-dimensional sodium dodecyl sulfate electrophoresis profiles of the main fraction of organelles.

In the current examine, we describe a new process using freezing-thawing to density gradient resolution of Nycodenz for one-step separation of organelles from the rat liver and subsequent proteome evaluation of subcellular fractions. To put together two-dimensional electrophoresis (2-D PAGE) profiles of tissue organelles, we carried out one-step subcellular fractionation of rat liver homogenate using …

Isolation of Peroxisomes from Mouse Brain Using a Continuous Nycodenz Gradient: A Comparison to the Isolation of Liver and Kidney Peroxisomes.

Isolation of Peroxisomes from Mouse Brain Using a Continuous Nycodenz Gradient: A Comparison to the Isolation of Liver and Kidney Peroxisomes.

In the central nervous system (CNS) peroxisomes are current in all cell varieties, particularly neurons, oligodendrocytes, astrocytes, microglia, and endothelial cells. Brain peroxisomes are smaller in measurement in contrast to peroxisomes from different tissues and are due to this fact referred to as microperoxisomes. We have established a purification process to isolate extremely purified peroxisomes …

Isolation of human blood dendritic cells by discontinuous Nycodenz gradient centrifugation.

Isolation of human blood dendritic cells by discontinuous Nycodenz gradient centrifugation.

The most potent antigen presenting cell current in peripheral blood, lymphoid and non-lymphoid tissue is the dendritic cell (DC). The research of human DC has been restricted by their low frequency within the tissues and the dearth of a really DC particular floor marker to help in identification and isolation. Standard methods for the isolation …

Separation of endocytic vesicles in Nycodenz gradients.

Separation of endocytic vesicles in Nycodenz gradients.

The endocytosis of 125I-labeled asialofetuin by rat hepatocytes was studied utilizing Nycodenz/sucrose gradients. It was proven in pulse chase experiments that the ligand endocytosed initially (after half of to 1 min) was in small, slow-sedimenting vesicles of comparable sizes. The vesicles containing the ligand elevated in measurement, and after about 2.5 min 20-30% of the …

Isolation of the major subcellular organelles from mouse liver using Nycodenz gradients without the use of an ultracentrifuge.

Isolation of the major subcellular organelles from mouse liver using Nycodenz gradients without the use of an ultracentrifuge.

Commonly, subcellular organelles equivalent to nuclei, mitochondria, lysosomes, and Golgi membranes are remoted first by differential centrifugation in low-speed or high-speed centrifuges after which purified by gradient centrifugation in ultracentrifuges. We have ready these organelles using a brand new high-speed centrifuge (28,000 rpm max) which permits the era of larger radial centrifugal forces (rcfs) than …

States of phage T3/T7 capsids: buoyant density centrifugation and cryo-EM.

States of phage T3/T7 capsids: buoyant density centrifugation and cryo-EM.

Mature double-stranded DNA bacteriophages have capsids with symmetrical shells that usually resist disruption, as they need to to outlive within the wild. However, flexibility and related dynamism help operate. We describe biochemistry-oriented procedures used to seek out beforehand obscure flexibility for capsids of the associated phages, T3 and T7. The main procedures are hydration-based buoyant …

Studies of dihydroxyacetone phosphate acyltransferase in rat small intestine. Subcellular localization and effect of partially hydrogenated fish oil and clofibrate.

Studies of dihydroxyacetone phosphate acyltransferase in rat small intestine. Subcellular localization and effect of partially hydrogenated fish oil and clofibrate.

The subcellular localization of dihydroxyacetone phosphate acyltransferase (DHAPAT) exercise in rat small gut was investigated by Nycodenz-gradient centrifugation. We discovered that DHAPAT had a predominant peroxisomal distribution, with a separate enzyme exercise positioned in the microsomal fraction, the identical distribution as discovered in rat liver. The effect of feeding rats on a weight loss plan with …
