L-Glutamine is an essential amino acid that is a crucial component of culture media that serves as a major energy source for cells in culture.
L-Glutamine is an essential amino acid that is a crucial component of culture media that serves as a major energy source for cells in culture. L-Glutamine is very stable as a dry powder and as a frozen solution. In liquid media or stock solutions, however, L-glutamine degrades relatively rapidly. Optimal cell performance usually requires supplementation of the media with L-glutamine prior to use.

Retinoic acid (RA) is a vitamin A-derived, non-peptidic, small lipophilic molecule that mediates the functions of vitamin A required for growth and development. It affects gene transcription and modulates a wide variety of biological processes like Cell Proliferation, Differentiation, including Apoptosis. Retinoic Acid mediated gene transcription depends on the rate of transport of Retinoic Acid to target cells and the timing of exposure of Retinoic Acid to RARs (Retinoic Acid Receptors) in the target tissues

5-Chloro-2'-deoxyuridine (CldU) is a thymidine analog that is readily incorporated, following phosphorylation, into newly synthesized DNA in place of thymidine.
5-Chloro-2′-deoxyuridine (CldU) is used as a thymidine analogue to study the miscoding potential of hypochlorous acid damage to DNA and DNA precursors. When used with antibody based immunofluorescent imaging, 5-Chloro-2′-deoxyuridine incorporation may be used in protocols to identify sites of DNA replication. CldU may be used as a labeling substrate in conjunction with other halogenated uridine labeling substrates such as bromodeoxyuridine (BrdU) and/or iododeoxyuridine (IdU).

Coenzyme A is an essential cofactor in enzymatic acetyl transfer reactions. The principal biologically active forms of pantothenic acid are coenzyme A (CoA) and acyl carrier protein (ACP). In CoA, the business center of the molecule is the pantothenic acid metabolite 4'-phosphopantetheine. Coenzyme A is comprised of 4'-phosphopantetheine linked by an anhydride bond to the nucloetide adenosine 5'-monophosphate. 4'-Phosphopantetheine itself is comprised of pantothenic acid linked at one end, via an amide bond, to beta-mercaptoethylamine, derived from L-cysteine, and at the other end to a phosphate group. The sulfhydryl group of 4'-phosphopantetheine, which is the business end of the coenzyme, forms thioesters with acyl groups producing acyl-CoA derivatives, including acetyl-CoA.
Coenzyme A facilitates removal of lipid peroxides by increasing mobilization of fatty acids, and promote repair of plasma membranes by activating phospholipid synthesis.

Cesium chloride, an inorganic compound, is an important source of cesium ions in a variety of applications. Its crystal structure forms a major structural type where each cesium ion is coordinated by 8 chlorine ions. Cesium chloride occurs naturally in mineral waters and as an impurity in carnallite (up to 0.002%), sylvite and kainite. Less than 20 tonnes of CsCl is produced annually worldwide, mostly from a cesium-bearing mineral pollucite.
