Citric acid 1 %

Citric acid 1% as a solution is an ingredient for a variety of laboratory uses, especially for staining kits such as the Campbell-Switzer silver plating kit. In its role as a weak organic acid, chemically known as C6H8O7, citric acid plays a key role in modulating pH, regulating enzymatic activity and improving staining capacity. Its action as a chelator binds metal ions, enhancing the efficiency of many biochemical reactions.
The use of this 1% citric acid solution enables uniform and well-defined staining in histological and cytological preparations. The addition of this solution can effectively visualize details of cell nuclei, membranes or pathological changes in tissue sections or smears, especially in hematoxylin-based nuclear staining.
