Methylene Blue Borax Solution 1%, aqueous, fulfills a critical role in microbiology and histology laboratory environments. As an integral part of Löffler staining, a differential staining method, it is used to label diphtheria bacteria and other microorganisms. This process is based on the chemical property of methylene blue, an oxidative stain that binds acid groups in cell structures, making them visible.

The additional ingredient sodium tetraborate decahydrate, commonly known as borax, acts as a buffer solution. Its role is to stabilize the pH, which allows for effective and uniform staining. This results in better visualization of microscopic structures and thus more precise analysis.

Furthermore, the methylene blue borax solution can be used to stain nucleic acids in electrophoresis gels. This application results in clear, visible bands that can be used to identify and distinguish DNA and RNA fragments. After using this solution, a refined optical differentiation of biological structures results, which facilitates and optimizes both diagnosis and evaluation.
