Medchemexpress LLC P-nitrophenyl α-L-fucoside | 10231-84-2 | MFCD00063697 | 98.5% | C12H15NO7 | 10MG
p-Nitrophenyl α-L-fucoside is a chromogenic substrate used to determine α-L-fucosidase activity in biochemical assays. Enzymatic hydrolysis releases p-nitrophenol, producing a colorimetric signal measurable by spectrophotometry. The reagent is supplied with high purity for research use.
- Chromogenic substrate that releases p-nitrophenol upon enzymatic hydrolysis.
- Enables colorimetric spectrophotometric determination of α-L-fucosidase activity.
- High purity (98.5%) suitable for assay development and enzyme characterization.
- Compact milligram package sizes convenient for small-scale experiments.
- Chemical formula C12H15NO7 and molecular weight 285.25 facilitate calculation of assay concentrations.

Medchemexpress LLC Formaldehyde dehydrogenase, Pseudomonas sp | 9028-84-6 | 5 U
Formaldehyde dehydrogenase is a widely occurring enzyme that catalyzes S-hydroxymethylglutathione in the presence of NAD. It detoxifies formaldehyde within cells by capturing and limiting it from reaching a toxic level. This enzyme can be studied in research on *M. tuberculosis*. It appears as a solid, white to off-white in color.
- Catalyzes S-hydroxymethylglutathione in the presence of NAD
- Detoxifies formaldehyde within cells by limiting toxic levels
- Valuable for research on *M. tuberculosis*
- White to off-white solid appearance
- Activity loss of ≤10% after 7 days at 37°C (powder)
- Activity inhibited by N2+, Pd2+, Hg2+, 4-chloromercuric benzoic acid, and fluorophenylmethylsulfonyl
- Easily soluble in water, but solution is unstable and should be prepared for immediate use
- Optimum pH is 7.3-7.6
- Reversible inactivation at pH 5.0, irreversible inactivation above pH 9.0
