Technical Data
Epithelial Membrane Antigen (EMA, CA15-3, Polymorphic Epithelial Mucin, PEM, Sialomucin or Episialin, MUC-1)
Epithelial Membrane Antigen, also referred to as EMA, CA15-3, Polymorphic Epithelial Mucin, PEM, Sialomucin or Episialin and MUC-1 is a glycoprotein of variable molecular weight, expressed by many glandular epithelial cells. Epithelia of breast, (acini and ducts), exocrine pancreas, bladder, gastrointestinal tracts, thyroid, endometrium and respiratory tract are generally EMA positive.

Suitable for use in Immunohistochemistry. Other applications not tested.

Recommended Dilution:
Immunohistochemistry: 1:25-1:50 (streptavidin:biotin)
Formalin-fixed, paraffin-embedded tissue sections can be stained successfully but require heat treatment to restore antigenicity, before staining. This involves exposure of tissue sections to boiling 0.01M citrate buffer, pH 6.0 for 25-30 minutes or for 2-3 minutes at elevated pressure.

Optimal dilutions to be determined by the researcher.

Tissue culture supernatant

Storage and Stability:
May be stored at 4°C for short-term only. For long-term storage, store at -20°C. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
