General description

Immersion oil is a clear, viscous liquid with optimized refractive properties, specifically modified to closely approximate the refractive index (RI) of glass (ne = 1.5). It is used in conjunction with an objective lens to enhance the resolving power.

Application

Immersion oil is used for high-resolution (1000X) light microscopy work in conjunction with an oil immersion objective lens to optimize microscopic examinations of histological, cytological, hematological, and bacterial specimen material after it has been fixed, embedded, stained, or counterstained, and mounted.

Principle

Immersion oil is applied dropwise to stained and mounted or non-mounted specimen material to form a clear film between the specimen and the microscope lens to eliminate the deflection of incident light and thus substantially enhance the optical efficiency of the lens.

The catalytic mechanism of the cyclic amidohydrolase isatin hydrolase depends on a catalytically active manganese in the substrate-binding pocket. The Mn2+ ion is bound by a motif also present in other metal dependent hydrolases like the bacterial kynurenine formamidase. The

Total internal reflection fluorescence (TIRF) microscopy uses the evanescent field on the aqueous side of a glass/aqueous interface to selectively illuminate fluorophores within approximately 100 nm of the interface. Applications of the method include epi-illumination TIRF, where the exciting light

Visualizing overall tissue architecture in three dimensions is fundamental for validating and integrating biochemical, cell biological and visual data from less complex systems such as cultured cells. Here, we describe a method to generate high-resolution three-dimensional image data of intact
