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
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 4-Vinylphenol | 2628-17-3 | MFCD00017593 | 120.15 | 100 MG
4-Vinylphenol, a metabolite found in medicinal herbs and wild rice, induces apoptosis, inhibits blood vessel formation, and suppresses invasive breast tumor growth in vivo. It is also produced by lactic acid bacteria in wine.
- Reduces cell viability in parental MDA-MB-231 cells.
- Reduces sphere formation and vimentin expression on CSCs in breast cancer.
- Suppresses cell proliferation in CSC-enriched MDA-MB-231 cells.
- Reduces ALDH1A1 expression in CSC-enriched MDA-MB-231 cells.
- Increases expressions of caspase 3, sensitizing CSC-enriched MDAMB-231 cells to apoptosis.
