Pyruvic acid is an intermediate in sugar metabolism and in enzymatic carbohydrate degradation (alcoholic fermentation) where it is converted to acetaldehyde and CO2 by carboxylase. In muscle, pyruvic acid (derived from glycogen) is reduced to lactic acid during exertion, which is reoxidized and partially retransformed to glycogen during rest. It improves coliform recovery when present in culture medium. It is involved in a metabolic regulatory pathway activated by mitochondrial oxidants. Pyruvate is involved in respiratory regulation in plants by interacting with alternative oxidase at a conserved cysteine residue. It may help prevent hydrogen peroxide mediated cell death.
Sodium pyruvate is utilized as a component in culture broth and media. Sodium pyruvate is used in Wallen fermentation medium to enhance the conversion of oleic acid to 10-ketostearic acid by Bacillus sphaericus. Sodium pyruvate has also been used to establish stably transfected human B cell lines.
Sodium Pyruvate has shown antioxidant properties and protective effects against oxygen radicals. Pyruvate is produced as part of glycolysis and is an intermediate in many metabolic pathways. It can be converted into acetyl CoA and enter the TCA Cycle.

5-Bromo-4-chloro-3-indolyl β-D-galactopyranoside, commonly known as X−Gal, is a histochemical substrate for β−galactosidase.
5-Bromo-4-Chloro-3-Indolyl-β-D-Galactopyranoside is used as indigogenic substrate for β-galactosidase, for detection of β-galactosidase-positive clones, and the identification of lac and bacterial colonies or phage plaques. It is the substrate of choice for blue-white selection of recombinant bacterial colonies with the lac+ genotype. X−Gal is cleaved by β−galactosidase to yield an insoluble blue precipitate. X−Gal is particularly useful in molecular biology applications to detect the activity of β−galactosidase which is frequently used as a reporter gene. In cloning, X−Gal is used to detect insertion of foreign DNA into the lacZ region of plasmid DNA using α-complementation which is based on vectors such as the pUC and the M13mp series that carry a fragment of the β-galactosidase gene encoding an α-fragment of β-galactosidase.

ML RR-S2 CDA is a synthetic cyclic dinucleotide (CDN) that contains non-canonical 2'5'-phosphodiester bonds and is an activator of stimulator of interferon genes (STING).1 It contains mixed linkages (ML) with both 2'5' and 3'5' linkages, which leads to increased thermal stability of human STING in a differential scanning fluorimetry (DSF) assay. ML RR-S2 CDA increases type I interferon production by THP-1 human monocytes relative to unmodified cyclic di-AMP (CDA; Item No. 17753), indicating the ML enhances its action at human STING. It induces expression of IFN-β and the pro-inflammatory cytokines TNF-α, IL-6, and Mcp-1 in murine bone marrow macrophages (BMM) isolated from wild-type, but not STING-/-, mice. ML RR-S2 CDA also induces IFN-β expression in peripheral blood mononuclear cells (PBMCs) isolated from donors carrying STINGWT/WT, STINGWT/REF, and STINGWT/HAQ alleles. In vivo, ML RR-S2 CDA initiates tumor regression and prevents tumor growth upon tumor cell reimplantation in 4T1 breast and CT26 colon cancer mouse xenograft models.
