What is multiplex immunostaining?
Multiplex immunostaining is a technique that allows the detection of multiple proteins in a single sample using different primary antibodies.
Why is blocking cross-reactivity important?
Blocking cross-reactivity is crucial to ensure accurate and reliable results when detecting multiple targets in immunostaining.
What role does microwave-mediated antibody stripping play?
Microwave-mediated antibody stripping helps to remove previously bound antibodies, allowing for the reuse of samples in multiplex staining.
How does fluorophore-tyramide work?
Fluorophore-tyramide enhances signal detection in immunostaining by amplifying the fluorescent signal from the target proteins.
What are the steps for preparing formalin-fixed paraffin-embedded samples?
The steps include de-waxing, rehydrating, and antigen retrieval using boiling sodium citrate solution.
