Examples of this technology include X-chrom (1971; manual) and Chromagen (1998). A 1981 review of various studies to evaluate the effect of the X-chrom contact lens concluded that, while the lens may allow the wearer to achieve a better score on certain color vision tests (specifically pseudoisochromatic plates like the Ishihara test), it did ...
Vanabins (also known as vanadium-associated proteins or vanadium chromagen) are a group of vanadium-binding metalloproteins. Vanabins are found almost exclusively in the blood cells , or vanadocytes , of some tunicates (sea squirts), including the Ascidiacea .
3,3′,5,5′-Tetramethylbenzidine or TMB is a chromogenic substrate used in staining procedures in immunohistochemistry as well as being a visualising reagent used in enzyme-linked immunosorbent assays (). [1]
Probe design for CISH is very similar to that for FISH with differences only in labelling and detection. FISH probes are generally labelled with a variety of different fluorescent tags and can only be detected under a fluorescence microscope, [4] whereas CISH probes are labelled with biotin or digoxigenin [5] and can be detected using a bright-field microscope after other treatment steps have ...
In chemistry, the term chromogen refers to a colourless (or faintly coloured) chemical compound that can be converted by chemical reaction into a compound which can be described as "coloured" (a chromophore).
Chromogranin-A (CgA) or parathyroid secretory protein 1 is encoded in the human by the gene CHGA.Cga is a member of the granin family of neuroendocrine secretory proteins. As such, it is located in secretory vesicles of neurons and endocrine cells such as islet beta cell secretory granules in the pancreas.
