Description
ROTI Fluor 645 NHS Ester is a fluorescent dye NHS ester with empirical formula C₃₈H₄₃N₃K₂O₁₃S₃ and a molar mass of 924,15 g/mol. Packed as 1 mg in plastic, it is intended for life-science use in histology, microscopy and fluorescent staining. The NHS ester group provides a reactive site for coupling the 645-class fluorophore to primary amines on biomolecules before staining or imaging. The 1 mg plastic pack is practical for small-scale labelling and for laboratories that prefer limited on-hand quantities. Manufacturer Carl ROTH states a molar mass of 924,15 g/mol and the empirical formula C₃₈H₄₃N₃K₂O₁₃S₃, which can be used for identity checks against internal records. Fluorescent dyes in this category are applied in histological and microscopic staining to render labelled structures visible. With the NHS ester as the reactive form, ROTI Fluor 645 NHS Ester can be incorporated into amine-labelling steps that precede fluorescence observation. The 1 mg plastic presentation, formula and molar mass constitute the core specifications for this chemically defined staining reagent in life-science laboratories.

Questions about ROTI Fluor 645 NHS Ester 1 mg
What is this article?
ROTI Fluor 645 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.
