Tyramine hydrochloride has been: coinfused with adenosine in control subjects and patients in order to reduce leg blood flow by 50% without affecting arterial blood pressure. labelled with fluorescence dyes (Atto 488 and Atto 655) to serve as a substrate for peroxidase in immunofluorescence analysis.Chemists synthesize chemical compounds that occur in nature in order to gain a better understanding of their structures. Synthesis also enables chemists to produce compounds that do not form naturally for research purposes.

Thymolphthalein is a phthalein dye used as an acid–base (pH) indicator.

Titanium Powders can also be used in medical area, such as cranial shell, heart pacemakers.

In the titanium gas atomisation (TGA) process, titanium is vacuum induction skull melted in a water cooled copper crucible, the metal tapped and the molten metal stream atomized with a stream of high pressure inert gas.

Indole TEST :  ( Indole produced by microorganisms )

The ability to degrade amino acid to identify end products to differentiate bacteria.Indole can be detected to the culture growth ( Pure bacterial culture must be grown in sterile tryptophan or peptone broth for 24-48 hours before performing the test. ) by reaction with 5 drops of Kovac’s reagent to produce a red  or red violet colour. 

KOVAC’S Reagent - ( para-Dimethylaminobenzaldehyde in isoamyl alcohol and Concentrated hydrochloric acid ) 

Tollens' reagent (chemical formula. ) is a chemical reagent used to distinguish between aldehydes and 

ketone functional groups along with some alpha-hydroxy ketones which can tautomerize into aldehydes.

reagent consists of a solution of silver nitrate, ammonia and some sodium hydroxide (to maintain a basic pH of the reagent solution). It was named after its discoverer, the German chemist Bernhard Tollens.
