If re-staining is not viable, alternatives include:
- Serial Sections: Using additional tissue sections from the same block can provide fresh slides for new staining. - Digital Imaging: High-resolution digital imaging and analysis might offer insights without the need for physical re-staining. - Multiplex Staining: Advanced techniques like multiplex immunohistochemistry allow multiple markers to be visualized on a single slide, reducing the need for re-staining.
