Citrate solution (antigen retriever) is a commonly used antigen retriever, which can be  used for antigen retrieval of paraffin-embedded sections and frozen sections fixed  with formaldehyde, paraformaldehyde, or other aldehyde reagents. 

Features: It can effectively remove cross-linking between proteins caused by aldehyde  fixation reagent, and fully expose the antigenic sites of paraffin-embedded tissue  sections, thereby significantly improving immunostaining effectiveness.
