PBS Buffer pH 7.4 - 20x Concentrate
The 20x concentrated PBS (Phosphate Buffered Saline) buffer with a pH of 7.4 is a highly concentrated buffer solution that must be diluted to the desired working concentration before use. PBS is a widely used buffer solution in biological and biochemical experiments because it maintains stable pH and osmotic conditions are similar for cells and tissues. The buffer consists of sodium phosphate, potassium phosphate, sodium chloride and potassium chloride. Diluting the 20x concentrate to 1x yields a buffer solution that can be used in various applications such as cell culture, immunoassays, protein purification, and storage of biological samples.
