Latent acetylcholinesterase in secretory vesicles isolated from adrenal medulla [PDF]
, 1981 A new procedure is described for the preparation of highly purified and stable secretory vesicles from adrenal medulla. Two forms of acetylcholinesterase, a membrane bound form as well as a soluble form, were found within these vesicles.

Density Gradient Centrifugation Studies of Rubella Virus
Experimental Biology and Medicine, 1966 SummaryRubella virus was grown in three different mammalian kidney cell lines. The resulting virus-containing supernates were concentrated by forced dialysis and were then studied for density on sucrose gradients. All of the virus preparations produced peaked infectivity bands with 99% of the infec-tivity concentrated in a band from 1.040 to 1.120 g ...

FEBS Open Bio, EarlyView.Metformin mediates mitochondrial quality control in Leber's hereditary optic neuropathy (LHON) fibroblasts carrying mtDNA mutations. At therapeutic levels, metformin activates AMPK signaling to restore mitochondrial dynamics by promoting fusion and restraining fission, while preserving mitochondrial mass, enhancing autophagy/mitophagy and biogenesis ...

Activation of Ciona sperm motility: phosphorylation of dynein polypeptides and effects of a tyrosine kinase inhibitor [PDF]
, 1991 A high molecular mass dynein ATPase polypeptide and a 18–20 kDa dynein light chain of Ciona sperm flagella are phosphorylated during in vivo activation of motility or in vitro activation of motility by incubation with cyclic AMP.

FEBS Open Bio, EarlyView.dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...

Preparation of Crude Subcellular Fractions by Differential Centrifugation
The Scientific World Journal, 2002 The employment of differential centrifugation to prepare crude fractions of subcellular particles from homogenates is often a necessary first step to a subsequent purification of one or more particles on a density gradient.

Deletion mutants of bacteriophage phiX174 [PDF]
, 1972 Mutants of bacteriophage phiX174 have been isolated that are less dense than wild-type phiX particles in CsCl. When mutant viral (+) strand DNA and wild-type complementary (-) strand DNA are hybridized, the resulting duplex molecules have single-stranded

Isolation of Ribosomal Particles from the Unicellular Cyanobacterium Synechocystis sp. PCC 6803 [PDF]
, 2017 Isolation of ribosomal particles is an essential step in the study of ribosomal components as well as in the analysis of trans-acting factors that interact with the ribosome to regulate protein synthesis and modulate the expression profile of the cell ...
