Depositors Notes: This antibody binds specifically to the surface of primordial germ cells and a variety of adult apical epithelium including oviduct and proximal kidney. This antibody also recognizes antigen in olfactory pits and membranous portions of fins in zebrafish PMID: 19302835.
Epitope Location or Sequence: EMA-1 recognizes short chain (monofucosylated polylactosamine) and long chain (mono- and difucosylated polylactosamine) glycolipids of cell surface glycoproteins specific of primordial germ cells.
Additional Information: This antibody was originally described and characterized in [Hahnel, A.C., and Eddy, E.M. (1986). Cell surface markers of mouse primordial germ cells defined by two monoclonal antibodies. Gamete Research 15, 25-34]. RRID:AB_531885
Recommended Applications: FACS, FFPE, Immunofluorescence, Immunohistochemistry, Western Blot

Storage and Handling Recommendations
Although many cell products are maintained at 4°C for years without loss of activity, shelf-life at 4°C is highly variable.
To ensure retention of antibody activity, we recommend aliquotting the product into two parts:
1) a volume of antibody stored at 4°C to be used within two weeks.
2) the remaining product diluted with an equal volume of molecular grade glycerol and stored at -20°C.
While optimal Ig concentration for an application will vary, a good starting concentration for immunohistochemistry (IHC),
immunofluorescence(IF) and staining is 2-5 µg/ml.
For Western blots, the concentration is decreased by one order of magnitude (that is, 0.2-0.5 µg/ml).
All cell products contain the antimicrobial ProClin. See our FAQ section for additional information.
