Description
2-keto-D-gluconic acid is found in the carrageenan polysaccharide of Irish moss and can be used as a stabilizer in the storage of biological materials. 2-keto-D-gluconic acid exhibits antimicrobial properties against species of Pseudomonas that cause plant disease. Genes for metabolism of 2-keto-d-gluconic acid are controlled by the UxuR regulon in E. coli. 2-keto-D-gluconic acid is converted to D-mannonate by the enzyme fructuronate reductase (EC 1.1.1.57). 2-keto-D-gluconic acid hemicalcium salt can be used to make D-erythorbic acid using an α-amylase enzyme. It can also be used to prepare D-ribulose and D-arabinose by heating in pyridine with a nickel acetate catalyst. Product Specifications 2-Keto-D-gluconic View product page →

Description
2-Ketoglutaric acid is a ketone derivative of glutaric acid and its anion is key intermediate in the Krebs cycle, after isocitrate and before succinyl CoA. It is an important nitrogen transporter and is transaminate along with glutamine to form glutamate. It can be used to differentiate microorganisms based on metabolic properties. It also possesses metabolic properties, decreasing the level of hydrogen peroxide in cell culture.

Firefly and Renilla Luciferase Assays are two of the leading reporter assays in the measurement of gene function and gene regulation both in vitro as well as in vivo. The luciferase assays are sensitive and convenient due to the absence of endogenous luciferase activity in most cell types and tissue. Firefly luciferase is a monomeric 62 kDa protein typically isolated from the firefly, Photinus pyralis, which catalyzes the ATP-dependent D-luciferin in the presence of oxygen and Mg2+ to oxyluciferin producing a yellow to greenish light (~560 nm).

Ketoconazole is a broad-spectrum imidazole antifungal effective against a variety of fungal species including Candida species, Blastomyces species, and Histoplasma species. Ketoconazole functions by inhibiting ergosterol synthesis and increasing fungal cell membrane permeability. It is also a CYP3A4 inhibitor used to identify p-glycoprotein/CYP3A-limited bioavailability and to study interleukin 1 chemotherapeutic effects. It has also been used to study drug interactions and to inhibit synthesis of aldosterone, cortisol, and testosterone.

FOR RESEARCH USE ONLY. NOT FOR USE ON HUMANS.

Kinetin is a plant hormone that promotes cell division. It is part of a group of hormones called cytokinins.

The plant hormones cytokinins (CKs) comprise a class of growth regulators involved in the stress response, senescence, photosynthesis, nutrient assimilation and mobilization, as well as modulation of a plant tissue’s ability to act as a sink or source of metabolites.

CKs are recognized by a subset of sensor histidine kinases (HKs) and the signal is transmitted to the nucleus via a multistep phosphorelay (MSP), thus activating the expression of target genes.
