Caspase substrates are a class of pharmacological agents that regulate apoptosis. Caspases are proteases that cleave specific proteins in the cell, leading to apoptosis. Pro-apoptotic proteins activate caspases, while anti-apoptotic proteins inhibit them. Caspase substrates can be either pro-caspase or anti-caspase, depending on the desired effect. They may also be used to regulate caspases without affecting their activity. The caspase substrate is cleaved by caspases and releases a polypeptide fragment that triggers apoptosis in some cells, but not others. For example, the Hl-60 cell line is resistant to the pro-apoptotic effects of the substrate because it contains an anti-apoptotic protein called Bcl-2. In contrast, myocardial cells contain pro-apoptotic proteins and are sensitive to the pro-apoptotic effects of the substrate. In

It is also used as a chromogenic substrate for beta-galactosidase, alpha-mannosidase, alpha-fucosidase, and alpha-N-acetylgalactosaminidase. 4MMB Cellobiose Haptaacetate is a conjugate that can be used to measure the activity of beta-glucuronidase and beta-xylosidase. This product is suitable for use in diagnostics, ligands, food testing, environmental testing, and culture media.

Hexadecanoylamino-4-methylumbelliferyl b-D-galactopyranoside is a substrate used for the diagnosis of Krabbe disease. Krabbe disease (globoid cell leukodystrophy/ galactosylceramide lipidosis), is a rare and often fatal lysosomal storage disease that results in progressive damage to the nervous system. It is inherited in an autosomal recessive pattern and involves dysfunctional metabolism of sphingolipids (MG44866 b-D-Galactosylsphingosine - Synthetic)

A sensitive fluorogenic substrate for fluorometric and UV-spectrophotometric assays of phosphatases. It is used for the detection of C. perfringens because acid phosphatase is a highly specific indicator for C. perfringens.

Fluorescein mono-b-D-galactopyranoside or FMG is a fluorogenic substrate for beta-galactosidase. The fluorophore fluorescein is released after enzymatic cleavage, exhibiting a greenish fluorescent. This substrate is particularly valuable in gene expression studies (e.g., lacZ reporter assays) and as a probe for cell-based assays for real-time monitoring.

FLsharp™ - Phosphate, disodium salt is a fluorogenic water soluble substrate for phosphatase enzymes. After cleavage of the substrate by phosphatase activity an insoluble product is formed that is highly fluorescent in the solid state. Upon UV irradiation this very stable fluorophore emits green light in the 530 nm range for an extended period of time. FLsharp™ - Phosphate is a unique substrate - optimized for the detection of phosphatase activity in solid matrices such as agar media, tissuesections or microscopic preparations. FLsharp™ - Phosphate, disodium salt is used in microbiology as asubstrate for bacterial phosphatases. The substrate is suitable to detect the specific phosphatase activity of S. aureus or C. perfringensin food samples or clinical samples. Colonies growing on plating media supplemented with FLsharp™ emit green light upon UV light excitation(Excitation max: 365 nm; emission max: 530 nm). The enzyme product formed from FLsharp™ in agar plating media enables high precision for the localization of the relevant colonies on the plate. As a result small bacteria colonies of phosphatase-positive bacteria can be detected already after a short incubation time.  In cytochemical and histochemical imaging FLsharp™ - Phosphate, disodiumsalt can be used as a substrate for Alkaline Phosphatase (AP)-coupled antibodies. The fluorophore that is released from FLsharp™ - Phosphateby phosphatase activity will precipitate. This insoluble fluorophoreen ables a precise localization of the antibody-bound epitope in cells or tissues under a fluorescence microscope or fluorescence imaging system. The green fluorescence of FLsharp™ can be clearly differentiated from autofluorescence or counterstainings such as (blue) DAPI or (red) Alexafluorophores.
