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
