10% NBF is a commonly used general purpose histological fixative, widely employed in preparing samples for light microscopy.10% neutral buffered formalin (NBF) is considered the gold standard fixative in immunohistochemistry (IHC) due to its ability to effectively preserve tissue morphology, maintain antigen integrity for antibody binding, and be readily compatible with routine tissue processing, making it a widely used and reliable choice for accurate IHC analysis across various tissue types.Key benefits of using 10% NBF for IHC
Good tissue preservation:NBF effectively cross-links proteins within the tissue, preserving cellular architecture and morphology, which is crucial for accurate interpretation of IHC staining patterns.
Wide antigen compatibility:While some antigen epitopes may be affected by fixation, NBF generally preserves a broad range of antigens, allowing for diverse IHC staining applications.
Ease of use and processing:NBF is readily available, easy to handle, and integrates seamlessly into standard tissue processing workflows, including paraffin embedding.
Cost-effective:Compared to other fixatives, 10% NBF is generally considered a cost-effective option for routine IHC analysis.
Reproducible results:Due to its consistent composition and fixation properties, NBF helps ensure reproducible IHC staining results across different laboratories and studies.
