Aldol® 515 N-glutaryl-L-phenylalanine amide is a chromogenic and fluorogenic enzyme substrate used for detection of L-glutamate-phenylalanine (GluPhe)-specific peptidase activity. The colorless enzyme substrate is cleaved the GluPhe-specific peptidase, yielding development of orange-red coloration. In addition, red fluorescence is generated when Aldol® 355 fluorescence enhancer or a suitable matrix is present. Aldol® 515 N-glutaryl-L-phenylalanine amide can be used in enzyme assays and live bacterial cultures. Aldol® 515 N-glutaryl-L-phenylalanine amide is suitable for use in liquid and solid media, under aerobic as well as anaerobic conditions.

Chromogenic substrate for β-D-glucuronidase (GUS) yielding a magenta precipitate. It is used fordetection of GUS+ bacterial colonies as analternative to 5-bromo-4-chloro-3-indoxyl-β-D-glucuronide (X-GlcA).

5-Bromo-4-chloro-3-indoxyl-alpha-L-arabinopyranoside is a fluorogenic substrate that can be used in enzyme and chromogenic assays. It is a high purity, stable product with a CAS number of 53673-61-7. This product has been shown to have fluorescence properties under acidic conditions, as well as chemiluminescence properties when exposed to an oxidizing agent. This compound can be used for the detection of bacterial activity in culture media and for the detection of pathogens in environmental samples. The conjugate can also be used for food testing.

Aldol 495 nonanoate is a bioluminescent substrate that can be used to measure the activity of Aldolase, which is an enzyme that catalyzes the conversion of glyceraldehyde-3-phosphate and dihydroxyacetone phosphate to D-glyceraldehyde. This substrate is used in various diagnostic assays, including food testing and staining. Aldol 495 nonanoate was developed by Cymit Quimica Pharmaceuticals and has been patented by EP 2427431 and US 8940909.

Reducing co-substrate for heme peroxidases; test reagent in microbiology

4-Aminoantipyrine has been used as an analgesic and anti-inflammatory agent. It can also target peroxidase enzymes to produce a red color

Aldol® 495 beta-D-galactopyranoside is a chromogenic and fluorogenic enzyme substrate used for detection of beta-galactosidase activity. The colorless enzyme substrate is cleaved by lactose-utilizing bacteria in liquid or solid media, yielding orange color as well as green fluorescence if a fluorescence enhancer or a suitable matrix are present. Aldol® 495 beta-D-galactopyranoside can also be used in beta-gal reporter gene assays or for identification of beta-gal positive transformants on agar plates. Aldol® 495 beta-D-galactopyranoside can be used under aerobic and anaerobic conditions.

4-Nitrophenyl 2-azido-2-deoxy-a-D-galactopyranoside is a superior chromogenic substrate for the precise determination of alpha-D-galactosidase enzyme activity. This substrate features a unique 2-azido moiety providing enhanced sensitivity and specificity in biochemical assays. Upon enzymatic cleavage, it releases the highly fluorescent compound 4-nitrophenol, which simplifies quantification and tracking of enzyme activity in applications such as drug discovery, genetic studies, and enzyme inhibition assays.

4-Nitrophenyl 2-O-(2,3,4,6-tetra-O-acetyl-b-D-glucopyranosyl)-4,6-O-benzylidene-b-D-glucopyranoside is a compound that is used in gene expression profiling. It has been shown to be an effective inhibitor of glutamicum and corynebacterium glutamicum. 4NPBG can inhibit the production of acid molecules by blocking the activity of cytochrome P450 enzymes in the cells of these bacteria. The compound also inhibits cellular transport and membrane transport genes in these species. This inhibition prevents the synthesis of nucleic acid molecules such as RNA and DNA.
