PBS buffer premixed tablets, pH 7.4, are widely used in biological and biochemical research for maintaining a stable pH environment. They are essential in cell culture applications, where they provide an isotonic solution for washing cells and preparing media. These tablets are also utilized in immunoassays, such as ELISA, to dilute antibodies and wash plates, ensuring consistent results. In molecular biology, PBS is commonly used for sample preparation, including DNA and protein extraction, as it helps maintain cellular integrity. Additionally, it serves as a diluent for various reagents and is employed in histology for tissue fixation and staining processes. The convenience of premixed tablets ensures accurate and reproducible buffer preparation, saving time and reducing errors in laboratory workflows.
