Electron Microscopy Sciences Formaldehyde 0.2% Chromic Acid .01% in Sodium Cacodylate Buffer, 7.4 pH 10 ML
Premixed, prebuffered fixatives, are pH adjusted for immediate laboratory use. They are freshly prepared upon receipt of order to ensure maximum shelf life. The fixatives are filled in 20 ml glass vials (10 ml/vial). This allows for the immediate fixation of your specimens without costly and time consuming transfer associated with ampoule contained fixatives. Formaldehyde .2% Chromic Acid .1% in Sodium Cacodylate.
pH: 7.4
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

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.
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
