This can be buffered to the neutral pH to kind 10% Neutral Buffered Formalin (NBF). Fixation will preserve the morphology, limit the loss of molecular factors into Alternative, stop decomposition and autolysis, and to attenuate microbial/fungal development. 10% NBF as well as almost all of the other fixatives applied right now improve appealing properties and minimize undesirable Houses of the other microscopic examination on the tissue (Eltoum et al. 2001a; Eltoum et al. 2001b).
