The shavings were then immunostained — bathed in a special reagent that would mark the presence of abnormal proteins with a bright, telltale red or brown stain on the surface of the tissue.
The capsule robot is one centimeter in diameter and three centimeters in length, with 1.5-centimeter-long feet that open on demand and press into the surface of the tissue to increase friction and anchor the device, says Sitti.
These are sheet-like colonies formed by Pseudomonas (and other bacterial species) over the surface of the tissue they are infecting.
That typically happens between a 2-D sheet of electronics and a surface of the tissue.
This introduces a layer between the surface of the specimen and the speckle pattern, which can cause measurement error, as the speckle pattern is no longer directly attached to the surface of the tissue.
The surface of the tissue that spans the channel opening was subject to a prescribed normal pressure.
The diluted gels were applied to the epithelial surface of the tissue and remained in contact for 24 h.
The matrix solution was then deposited using an automatic vibration vaporization system (ImagePrep, Bruker Daltonics, Bremen, Germany) to cover the whole surface of the tissue section.
Furthermore, to avoid false negatives, only ultrahin sections in the first 1.5 µm from the surface of the tissue block were examined.
However, the methods that are used to record such waves in experiments on cardiac tissue are typically constrained to probe only the surface of the tissue.
When HA-Fc were used to probe the human tracheal airway sections, H3 HA-Fc bound extensively to the luminal surface of the tissue and was localized at the apical surfaces of cells.
