General description

Phosphate-citrate buffer is a common buffer used along with soluble horseradish peroxidase substrates such as o-phenylenediaminedihydrochloride (OPD) or tetramethylbenzidine (TMB). It gives a pH of 5.0 with an excellent buffering capacity. The phosphate-citrate buffer tablets can be used to prepare a 0.05 M phosphate-citrate, pH 5.0, buffer solution. These tablets elicit a fast, convenient, and accurate method for the synthesis of phosphate citrate buffer solutions. They remove the time-consuming and tedious process of weighing individual components in buffer preparation. Phosphate-citrate buffer tablets have been manufactured from the highest quality components to exacting physical and chemical specifications to ensure performance and lot-to-lot consistency. Phosphate-Citrate Buffer tablets, pH 5.0, have been formulated as a substrate buffer in immunoassay procedures.

Reconstitution

One tablet dissolved in 100 mL deionized water yields a 0.05 M phosphate-citrate buffer, pH 5.0, at 25 °C. Store at room temperature.

Anderson-Fabry disease (AFD) is an inborn lysosomal enzymopathy resulting from the deficient or absent activity of the lysosomal exogalactohydrolase, α-galactosidase A. This deficiency, results in the altered metabolism of glycosphingolipids which leads to their accumulation in lysosomes, thus to cellular

Carcinogen exposures inscribe mutation patterns on cancer genomes and sometimes bias the acquisition of driver mutations toward preferred oncogenes, potentially dictating sensitivity to targeted agents. Whether and how carcinogen-specific mutation patterns direct activation of preferred oncogenes remains poorly understood. Here
