Studies of how fixation in ten% NBF interacts with histochemical and immunohistochemical staining are certainly restricted in number and most are based on comparatively extended situations of fixation in 10% NBF (≥ 36 hrs). Present-day periods of fixation in ten% NBF are actually lessened to < 24 several hours.
