Formaldehyde fixatives | The Microscopy Alliance | A ...

The fixative 10% buffered formalin is commonly used to preserve tissues for routine histology in many labs. The formaldehyde has a greater chance for oxidation in this concentration of tissue fixative and eventually the solution will start to drop in pH, in spite of the buffer. ... Tissues and organs should be fixed ...

Effects of Fixation and Tissue Processing on ...

Tissues fixed in formalin for long periods usually require prolonged exposure to proteolytic enzyme. It may be found that digestion time varies because of batch- to- batch variation in enzyme activity. Another pitfall with enzymatic antigen retrieval is that poorly fixed tissues are easily over digested with resulting loss of morphological detail.

Frozen vs. Formalin-Fixed Paraffin-Embedded Tissue ...

When FFPE tissues are used for IHC, the standard histology fixative of 10% neutral-buffered formalin (NBF) is sufficient. Fixation time prior to paraffin embedding is generally limited to 24-48 hours, which greatly contributes to preservation of antigen integrity. Advantages of FFPE section IHC include excellent tissue morphology and ease of ...
