Applications A thiol reactive fluorescent probe for the labelling of proteins. Rhodamine dyes are used extensively in various aspects of fluorescence microscopy because of their brightness and resistance to photobleaching. They are valuable in studies directed at probing changes in orientation and mobility of proteins using fluorescence anisotropy measurements. It is a mixture of the 6-Iodo and 6-chloro.

Applications Indoleacetic Acid is the most common and naturally occuring plant hormone in the auxin class of hormones. It effects cell elongation, cell division as well as plant growth and development.

Applications Pyruvic Acid-13C2 is an intermediate in synthesizing L-Lactic Acid-d3 Sodium Salt (L113503), a labelled sodium salt of L-Lactic Acid (L113500). L-Lactic Acid occurs in small quantities in the blood and muscle fluid of man and animals. The lactic acid concentration increases in muscle and blood after vigorous activity. L-(+)-Lactic acid is also present in liver, kidney, thymus gland, human amniotic fluid, and other organs and body fluids.
