Hoyer’s technical manager, Bjarne Nør, provides an introduction to medium and high voltage motors.Ĭan I use PVA instead of Hoyer’s coverslip? In 2018, Hoyer will be expanding its product series with a range of medium voltage motors with voltages ranging from 3 kV to 11 kV, which are well-suited for heavy loads. Krantz, G.W., Water D.E., Behan-Pelletier, V., Cook, D.R., Harvey, M.S., Keirans, J.E., Krantz, G.W., Lindquist, E.E., Norton, R.A., OConnor, B.M., & Smith, I.M. Hoyer’s mediun contains 50 mL distilled water, 30 g Crystalline gum arabic (or gum acacia), 200 g Chloral hydrate, 20 mL Glycerin (Krantz et al., 2009). What is the composition of Hoyer’s mediun? Various modification of the mixture of gum arabic with chloral hydrate can be used for mounting of small arthropods as well as some helminths. Vectashield is probably the most widely used, and is fine for most applications. There are a number of antioxidants (the antifade component) in a variety of solutions commercially available. An example of this is the apparent bending of a stick when placed in water. As light passes from one medium to another, it changes speed and bends. Mounting media should ideally have a refractive index (RI) as close as possible to that of the fixed protein (tissue) (approximately 1.53). You can also open DPX images with Adobe SpeedGrade in Windows and macOS, but it has been discontinued. You can open DPX images with various applications, such as ImageMagick (multiplatform), XnViewMP (multiplatform), and Apple Final Cut Pro (macOS). an adhesive used for mounting specimen slides for viewing under a microscope. The simplest type of mounting medium is air, or a saline-based buffered solution, such as PBS.ĭefinition of ‘mountant’ 1. Mounting medium is the medium that your sample is in while it is being imaged on the microscope. Tissue has an average reflective index of 1.53 to 1.54. Reflective index of the mounting media is also very important. Toluene is more volatile than xylene so bubbles are more likely to appear. Why is xylene used in mounting?īecause slides are usually mounted from xylene, xylene should be the solvent for the mounting media. The medium is important for the image formation as it affects the specimen’s rendition. The main purpose of mounting media is to physically protect the specimen the mounting medium bonds specimen, slide and coverslip together with a clear durable film. They are used to mount tissue sections directly after staining when the dye used is soluble in alcohol, xylene or other organic solvents such as most lipid dyes.ĭPX is a synthetic non-aqueous mounting medium for microscopy. The composition of the aqueous mounting media is based on distilled water. This product sets to a thin, adhesive layer that effectively cements the cover glass to the slide. Apply a small drop of Permount Mounting Medium onto the stained specimen and lay a cover glass on top. The formula contains an anti – oxidant to inhibit stain fading, and is completely soluble in xylene and toluene. Why DPX is a preferred mounting medium in histology? DPX is suitable for all staining techniques which are compatible with the use of alcohol and aromatic (xylene/ toluene) clearing agent. Why DPX is a preferred mounting medium in histology? In order to be an effective mounting medium, it is important that DPX has an optimised viscosity and refractive index (RI). Mounting medium is used to attach a coverslip to a microscope slide to protect the tissue during microscopy and storage.
