Submit a formalin-fixed, paraffin-embedded tissue

Formalin-fixed, paraffin-embedded (FFPE) tissue block

FFPE tissue section mounted on a charged, unstained slide

Ambient (preferred)

• Unlabeled/mislabeled block
• Insufficient tissue
• Slides broken beyond repair

Immunohistochemical staining and microscopic examination

If requested, an interpretive report will be provided

Specifications

• The antibody reacts with the heavy chain (mu-chain) of human IgM
• This antibody labels plasma cells, and various lymphocytes (the later depends on the methodology - i.e. frozen vs. paraffin)

 
Staining pattern

• Cytoplasmic (plasma cells) and cell surface membrane (lymphocytes)
