  Reagent - Wikipedia, the free encyclopedia
For example hydrochloric acid is the chemical reagent that would cause calcium carbonate to release carbon dioxide.
Similarly, but less obvious, hydrochloric acid is the chemical reagent that reacts with zinc to produce hydrogen, even though in this case the hydrogen comes from the acid and not the metal.
In another use of the term, when purchasing or preparing chemicals, "reagent" describes chemical substances of sufficient purity for use in chemical analysis, chemical reactions or physical testing.

 Grignard reaction - Wikipedia, the free encyclopedia
The disadvantage of the Grignard reagent is that they readily react with protic solvents (such as water), or functional groups with protons, such as alcohols and amines.
The reagent may also react with oxygen present in the atmosphere, inserting an oxygen atom between the carbon base and the magnesium halide group.
Grignard reagents are formed via the action of an alkyl or aryl halide on magnesium metal.

 Small Particle Reagent
If you look at the small particle reagent print after you have developed and rinsed it with water, you will notice that in the area of the latent print the water has beaded away from the latent fingerprint.
Small particle reagent dries silver on dark objects and dark on light-colored objects and is available in white also.
This needs to be done frequently during the spraying process because the particle reagent is heavier than the water and will settle to the bottom of the spray container.

 Transport Protein Delivery Reagent - Cambrex
Transport Reagent allows you to quickly and easily study cell and protein function, while avoiding the problems of DNA transfections (promoter interference, variable levels of transfection).
The conjugation of Transport Reagent and a cargo molecule occurs through the 2-pyridyldithio group on the reagent which forms a disulfide bond with any free thiol (cysteine) situated on the cargo molecule.
Coupling of Transport Reagent with cargo molecules is a simple process — simply incubate appropriate amounts of each component at room temperature for 15-30 minutes, dilute with culture medium and apply to culturing cells.

 Genial Anti-Clotting Reagent
Anti-clotting Reagent (ACR) is an enzyme mixture which when reconstituted helps rapidly breakdown the protein components (fibrin) of blood clots which can cause culture problems, particularly with amniotic and bone marrow samples.
The user must dissolve the dried ACR reagent in the stated amount of PBS and then filter it using a micro-syringe filter.
Since blood clots hinder the cell growth of the required cell types, the use of Anti-clotting Reagent allows for more rapid establishment of cell colonies with resultant quicker harvest times for the sample.

 Reagent Data - Homepage
Reagent Data is a comprehensive library of all reagents used in tradeskills in World of Warcraft.
Until now, authors who wanted to use reagent data either had to compile their own list (which is VERY time consuming) or rely on Sea (which provides a lot of unnecessary extras, is incomplete, and has a negative stigma).
This mod is essentially a replacement for Reagent Helper and took a single afternoon to develop from start to finish due in part to the flexibility of the Reagent Data library.
