General description

Sodium 5,5-diethyl barbiturate, also known as Barbital sodium, is a long-acting barbiturate that can significantly depress various metabolic processes at high doses. This weak acid has widespread applications in scientific fields, particularly as a buffering solution in biochemical and biological experiments due to its buffering capabilities. It is particularly well-suited for scenarios requiring lower buffer capacity without compromising pH stability. This buffering effect is achieved through the equilibrium between the acid and its corresponding anion, effectively stabilizing the pH within the desired range. Additionally, Sodium 5,5-diethyl barbiturate has potential applications in histology, and biochemical research, including uses in enzyme assays, cell structure staining, and electrophoresis.

Application

Sodium 5,5-diethyl barbiturate has been used as a component of Michaeli′s buffer, a commonly used buffer solution that helps maintain ideal conditions for histological and histopathological analyses. It is also utilized as a biological buffer in immunoelectrophoresis, hemolytic assays and fixative solutions.

Complement activation contributes to the systemic inflammatory response induced by cardiopulmonary bypass. At the cellular level, cardiopulmonary bypass activates leukocytes and platelets; however the contribution of early (3a) versus late (C5a, soluble C5b-9) complement components to this activation is unclear.
