This is buffered into a neutral pH to type ten% Neutral Buffered Formalin (NBF). Fixation will preserve the morphology, decrease the lack of molecular elements into solution, reduce decomposition and autolysis, and to reduce microbial/fungal development. ten% NBF in addition to most of the other fixatives used right now maximize appealing Homes and minimize undesirable Homes of the other microscopic examination on the tissue (Eltoum et al. 2001a; Eltoum et al. 2001b).
