Guanosine-5'-monophosphate is an ester of phosphoric acid with the nucleoside guanosine.

Supplier: MP Biomedicals

Guanosine is a purine nucleoside comprising guanine attached to a ribose (ribofuranose) ring via a β-N9-glycosidic bond. Guanosine can be phosphorylated to become guanosine monophosphate (GMP), cyclic guanosine monophosphate (cGMP), guanosine diphosphate (GDP), and guanosine triphosphate (GTP). These forms play important roles in various biochemical processes such as synthesis of nucleic acids and proteins, photosynthesis, muscle contraction and intracellular signal transduction (cGMP). When guanine is attached by its N9 nitrogen to the C1 carbon of adeoxyribose ring it is known as deoxyguanosine.
Guanosine is required for an RNA splicing reaction in mRNA, when a "self-splicing" intron removes itself from the mRNA message by cutting at both ends, re-ligating, and leaving just the exons on either side to be translated into protein. The antiviral drug aciclovir, often used in herpes treatment, is structurally similar to guanosine.

Hydrocortisone, a primary glucocorticoid secreted by the adrenal cortex. It has three times the anti-inflammatory potency of corticosterone but much lower Na2+ retention potency. Hydrocortisone, known more formally as cortisone (INN, USAN, BAN), is a steroid hormone, produced by the zona fasciculata of the adrenal gland. It is released in response to stress and a low level of blood glucocorticoids.

Protamine sulfate is a purified mixture of simple protein principles obtained from the sperm or testes of suitable species of fish, which has the property of neutralizing heparin. Because of having much basic amino acids (mostly arginine) protamine contains far greater nitrogen than other proteins. Its molecular weight is relatively small. Histone and other basic proteins in the testes of unmatured fishes convert into protamine along with the growth of the fishes. In the testes protamine takes the form of nucleoprotamine linked with DNA.

Sodium selenite is commonly used as a source of selenium in biological research, where selenium is an essential trace element that is normally provided by serum. Selenium is present in selenoproteins such as glutathione peroxidase and thioredoxin reductase, which contain the selenium analog of cysteine, selenocysteine. In particular, glutathione peroxidase has a role in detoxification in vivo as a scavenger of peroxides. Sodium selenite is included in various medium supplements for use in cell culture. Sodium selenite has been utilized in studies of cell proliferation and cancer research. It has been used to alter gene expression in HepG2 cells as analyzed by cDNA microarrays. Sodium selenite can inhibit zinc finger protein/DNA interactions. Sodium selenite has been shown to alter mitochondrial membrane potentials and thus potentially contribute to apoptosis.

Tris have been useful as buffers in a wide variety of biological systems. It has been used as a starting material for polymers, oxazolones (with carboxylic acids) and oxazolidines (with aldehydes). It does not precipitate calcium salts and is of value in maintaining solubility of manganese salts. It can be used for the direct standardization of a strong acid solution; the equivalence point can be determined either potentiometrically or by use of a suitable indicator such as 3-(4-Dimethylamino-1-naphthylazo)-4-methoxybenzenesulfonic acid. It is RNAse and DNAse-free. Tris is relatively non-hygroscopic ; but, if needed, it can be dried at 100 °C for up to 4 hours to remove any water.
Tris is used in pH control in vitro and in vivo for body fluids and in buffering systems for electrophoresis applications.Tris is used in assays used to characterize the activity and kinetics of the enzymes that catalyze SUMOylation of Small ubiquitin-like proteins (SUMO) and SUMO-dependent protein-protein interactions.
