[Virus-specific structures in Sendai virus infected Ehrlich ascitic carcinoma cells]. 1978

G K Vorkunova, and A G Bukrinskaia, and G G Miller

A virus-specific structure representing a ribonucleoprotein (RNP) associated with cell membranes was found in the cytoplasm of Sendai virus-infected cells of Ehrlich ascitic carcinoma. RNP could be separated from the membranes by recentrifugation of this structure in cesium chloride density gradient. In the liquid fraction, a structure with the same buoyant density possessing infectious activity was found. All structural polypeptides of virions with the exception of the membrane protein are found in the composition of the intracellular and extracellular structures.

UI	MeSH Term	Description	Entries
D008854	Microscopy, Electron	Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.	Electron Microscopy
D009698	Nucleoproteins	Proteins conjugated with nucleic acids.	Nucleoprotein
D010222	Parainfluenza Virus 1, Human	A species of RESPIROVIRUS also called hemadsorption virus 2 (HA2), which causes laryngotracheitis in humans, especially children.	Hemadsorption Virus 2,Human parainfluenza virus 1,Para-Influenza Virus Type 1,Parainfluenza Virus Type 1,Para Influenza Virus Type 1

D002499	Centrifugation, Density Gradient	Separation of particles according to density by employing a gradient of varying densities. At equilibrium each particle settles in the gradient at a point equal to its density.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
