Fluorescent protein paraffin embedding
WebJun 8, 2024 · The two main methods for preserving tissues for IHC or immunohistology are paraffin embedding and freezing. While there is no universal preservation method suitable for detecting all antigens, the vast majority can be successfully detected in formalin-fixed paraffin-embedded (FFPE) tissue sections. WebThe pairing of a primary antibody and secondary antibody (specific for the host species of the primary) that is conjugated to a fluorophore is known as indirect staining. The use of primary antibodies conjugated to …
