Description
ROTI Fluor 550 NHS Ester is a fluorescent dye NHS ester with empirical formula C₃₆H₄₁N₃K₂O₁₃S₃ and a molar mass of 898,11 g/mol. The reagent is packed as 1 mg in plastic for laboratory use in life science, particularly histology, microscopy and fluorescent staining. NHS esters of fluorescent dyes are employed to introduce a covalent fluorescent label onto primary amines of biomolecules prior to imaging or staining. The 1 mg plastic pack supports small-scale labelling work and inventory control in research settings. Specification data from manufacturer Carl ROTH give the molar mass as 898,11 g/mol together with the empirical formula C₃₆H₄₁N₃K₂O₁₃S₃, enabling straightforward identity confirmation on receipt. In histology and microscopy, such fluorescent dyes are used to stain specimens so that labelled structures can be visualised. The NHS ester format is the reactive functionality for coupling the 550 fluorophore to amine-containing targets. Laboratories can therefore treat ROTI Fluor 550 NHS Ester as a defined chemical reagent for fluorescent staining workflows, relying on the stated formula, molar mass and 1 mg plastic presentation as the documented product attributes.

Questions about ROTI Fluor 550 NHS Ester 1 mg
What is this article?
ROTI Fluor 550 NHS Ester 1 mg is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Microscopy accessories, inside Microscopy & histology, in Lab instruments.
Microscopy accessories are the stages, the holders, the bulbs and the cameras' adapters that are not the objective and not the slide. A C-mount adapter of the wrong factor crops or vignettes the image. The accessory has to name the microscope it fits.
A light microscope forms an image with glass lenses and transmitted or reflected light. A stereo microscope is the lower-magnification instrument for dissecting and for looking at a surface. Fluorescence needs a light source and filters matched to the dye. Histology is the preparation that makes a tissue readable: fixation, a cassette, a section, a stain. The objective's magnification and numerical aperture decide the resolution. The slide and the cover glass decide whether the section sits in the focal plane. Stains and dyes as substances are identified on PubChem. Papers on the methods are on PubMed.
