Supelco Inc Formaldehyde solution 500ml
Formaldehyde (formalin) is produced by oxidation of methanol. It is made of 37% formaldehyde and impurities such as methanol, small amounts of formic acid, aldehydes and ketones. It is used as a denaturant in formaldehyde-agarose gel electrophoresis of RNA. Application:Formaldehyde solution has been used as a fixing agent to fix cells during immunofluorescence imaging and for cross-linking cells during chromatin immunoprecipitation (ChIP) assay. Formaldehyde solution has been used for cross-linking/fixing of cells in ChIP (chromatin immunoprecipitation) assay. It has been used for fixing of cells for imaging. 500ml

Medchemexpress LLC P-nitrophenyl α-L-fucoside | 10231-84-2 | MFCD00063697 | 98.5% | 285.3 g/mol | C12H15NO7 | 5 MG
p-Nitrophenyl α-L-fucoside is a chromogenic substrate used to quantify α-L-fucosidase activity. Enzymatic hydrolysis releases p-nitrophenol, producing a yellow chromophore that can be measured spectrophotometrically for end-point or kinetic assays. Supplied as a high-purity solid for reagent preparation.
- Chromogenic substrate for α-L-fucosidase assays.
- Releases p-nitrophenol detectable at ≈405 nm for spectrophotometric readout.
- High purity (~98.5%) suitable for quantitative enzymatic studies.
- Supplied as a stable solid for easy dissolution and assay setup.
