The catheter can be advanced into the coronary arteries and a dye injected into the arteries (coronary angiography or arteriography). With the use of fluoroscopy (a special type of X-ray), the doctor can identify blockages in the coronary arteries as the dye moves through them.
Basic Dyes. Basic dye is a stain that is cationic (+ve charged) and so will react with material that is (-ve) negatively charged. This dye is usually synthetic, that act as bases, and which are actually aniline dyes.Their color base is not water soluble but can be made so by converting the base into a salt.asic dyes display cationic functional groups like-NR3+ or =NR2+. Since basic dye is a stain that is cationic or positively charged and it is the reason that it reacts well with material that is anionic or negatively charged. Basic dyes consists of amino groups, or alkylamino groups, as their auxochromes.
