The phrase "a electron dense" is not correct in English.
It should be "an electron dense" due to the vowel sound at the beginning of "electron." You can use it in contexts related to scientific discussions, particularly in fields like physics or biology, where electron density is a relevant concept.
Example: "The sample exhibited an electron dense region, indicating a high concentration of particles."
Alternatives: "an electron-rich" or "a high electron density."
A discontinuous layer of an electron dense substance was observed beneath the boarder between the endothelial layer and Descemet's membrane (fig 5).
Electron micrograph studies of B virus show a typical herpesvirus structure (6 ), including an electron dense core with viral DNA inside an icosapentahedral capsid surrounded by an amorphous tegument protein layer and a lipid envelope studded with viral glycoproteins.
Individual fibrils consist of a central capillary defined by an electron dense crystalline wall.
Upon interaction, the saccules form an electron dense interface with a constant width of 14 16 nm whereas the outermost saccule is closed by a thinner membrane ∼7 nm wide.
The synaptic ribbon for the mammalian auditory synapse is reported to progress from an electron dense bundle to an enlarged oval shape and attach to the active zone via a single link [ 6].
Based on previous morphological studies, an electron dense layer, morphologically similar to a basement membrane, has been observed on the luminal side of invertebrate blood vessels [3], [10] [12].
Centrosomes in Dictyostelium consist of a trilaminar disc shaped core surrounded by an electron dense corona (Moens, 1976; Roos, 1975; Ueda et al., 1999).
Endocytic vesicles were labeled with the fluorescent dye FM1 43, and after photoconversion (a process that translates the fluorescence into an electron dense polymer that darkens the vesicle lumen in the electron microscope), the fluorescence was visualized using EM analysis.
Often, an electron dense line, located between adjacent dendrites at a regular and even distance between them, could be seen within the extracellular space, and small pockets of accumulated uniform electron dense deposit could be seen between adjacent dendritic profiles (Fig. 2B).
