Phosphate buffer for histology
WebIn case you aren’t familiar with them, phosphate buffers are one of the two most important biological buffer systems in most multicellular organisms and are responsible for keeping the pH range of cellular fluid within the normal range (6.9 to 7.4).Since phosphoric acid has multiple dissociation constants, you can prepare phosphate buffers near … WebThe fixation of the histological specimen material of human or animal origin is commonly performed in a 4% or 10% Formaldehyde solution. Chemically, the 4 % Formaldehyde solution equals a 10 % Formalin solution. This Formaldehyde solution 4% is a ready-to-use working solution that is stabilized with phosphate buffer to protect tissue structures.
