]]> Calcium Chloride Dihydrate is a white deliquescent compound which is commonly used as a reagent in biochemistry. Calcium plays important roles in many biological processes, including signal transduction, muscle contraction, maintenance of cell membranes and cell wall stability. Calcium chloride is a soluble compound that can serve as a source of calcium ions in a solution. The compound can be useful for displacing ions from solution; for example, phosphate may be displaced from solution by calcium.

The post Dibasic Potassium Phosphate first appeared on Parnchem.

]]> Potassium Phosphate, Dibasic, Anhydrous (K2HPO4) is a reagent with a very high buffering capacity. Potassium Phosphate, Dibasic, Anhydrous is widely used in molecular biology, biochemistry, and chromatography. Potassium phosphate occurs in several forms: monobasic (KH2PO4), dibasic (K2HPO4), and tribasic (K3PO4). Neutral potassium phosphate buffer solutions may be prepared with a mixture of the monobasic and dibasic forms to varying degrees, depending on the desired pH. Potassium Phosphate buffers are very useful in numerous applications, but with the following limitations: precipitation of Ca2+ and Mg2+, inhibition of restriction enzyme activity, and interference in DNA ligation or bacterial transformation protocols. Potassium Phosphate, Dibasic, Anhydrous has been used to study the effects of freezing and thawing on the stability of proteins sensitive to conformational changes; it was found that Potassium Phosphate, Dibasic, Anhydrous buffers offered improved pH stability as opposed to NaP buffers. Potassium Phosphate, Dibasic, Anhydrous has also been used for the extraction of keratohyalin protein from bovine tissue. Potassium Phosphate, Dibasic, Anhydrous is also known as Dipotassium hydrogenphosphate, Dipotassium phosphate, and sec.-Potassium phosphate. Additional forms available: Potassium Phosphate, Dibasic, Anhydrous Potassium Phosphate, Monobasic Potassium phosphate tribasic Potassium phosphate tribasic monohydrate Potassium phosphate dibasic solution Potassium Phosphate Monobasic solution

]]> Potassium carbonate can be used for deproteinization. Mild drying agent where other drying agents such as calcium chloride and magnesium sulfate may be incompatible. Not suitable for acidic compounds, but can be useful for drying an organic phase if one has a small amount of acidic impurity. Potassium carbonate is also used in the synthesis of well-defined phosphate-methylated DNA fragments: It is shown that base deprotection can be accomplished in potassium carbonate/methanol without affecting the methyl phosphotriesters
