Ruthenium red electron microscopy
WebThe transmission electron microscope allows for access to inner bacterial ultrastructure when imaging ultrathin sections as well as cell wall-attached structures by negative staining, whereas scanning electron microscopy allows for the detection of structures on the bacterial cell surface alone or to study the interplay between pneumococci and … WebThe Ultrastructure of the Capsules of Diplococcus pneumoniae and Klebsiella pneumoniae Stained with Ruthenium Red Microbiology Society Volume 74, Issue 1 Research Article Free The Ultrastructure of the Capsules of Diplococcus pneumoniae and Klebsiella pneumoniae Stained with Ruthenium Red E.

WebChemicals included microscopy grade ruthenium red (Fluka, Buchs, Switzerland), microscopy grade glutaraldehyde (Ted Pella, Redding, CA), TLC-gradeL-lysine (Sigma), and osmium tetroxide(N99,95%,TedPella).Unstainedcontrolbiofilmswere exposed to HEPES buffer but were otherwise treated the same (Fig. 1). WebSummaryThe electron-dense marker which is thought to produce the ruthenium red surface staining is studied. This stain is prepared under conditions which should give its rise in cell surface membrane, and its nature and charge are tested electrophoretically and by measuring the turbidity, respectively.
