The above photo shows the positive results of the number 2 Marquis reagent presumptive drug test when used with a sample of opium. It is the primary presumptive test used in Ecstasy reagent testing kits. It can also be used to test for such substances as opiates (e.g. codeine, heroin), and phenethylamines (e.g. 2C-B, mescaline).
Murexide test is a color test for uric acid and some other purines. The (solid) sample is first treated with small volume of a concentrated acid such as hydrochloric acid, nitric acid, which is slowly evaporated away; subsequent addition of ammonia (NH 3) gives a purple color if uric acid was present, due to formation of murexide, or a yellow color that turns to red on heating if xanthine or ...
In pharmaceutical sciences, drug interactions occur when a drug's mechanism of action is affected by the concomitant administration of substances such as foods, beverages, or other drugs. A popular example of drug–food interaction is the effect of grapefruit on the metabolism of drugs .
Interactions between chemical compounds also is a frequent area of taxonomy, as are the major organic chemistry categories (protein, carbohydrate, lipid, etc.) that are relevant to the field. In the field of aroma and flavor alone, Flament gives a list of 300 contributing chemicals in green beans, and over 850 after roasting.
DMPX (3,7-dimethyl-1-propargylxanthine) is a caffeine analog which displays affinity for A 2 adenosine receptors, in contrast to the A 1 subtype receptors. [1] DMPX had 28 times and 15 times higher potency than caffeine in blocking, respectively, the peripheral and central effects of the adenosine agonist NECA.
If the antibodies interact with the antigen to form immune complexes, called agglutination, then the test is interpreted as positive. However, if too many antibodies that can bind to the antigen are present, then the antigenic sites are coated by antibodies, and few or no antibodies directed toward the pathogen are able to bind more than one ...
