Can you determine if it binds to the extracellular domain epitope of P-selectin on rat endothelial cells? Thank you very much! |
|||||||||
ANSWER: |
Thank you for your inquiry. Unfortunately this antibody is very unlikely to recognize the extracellular domain of the rat P-selectin, as it has been raised against a peptide surrounding amino acid 756. Indeed accordingly to SwissProt, amino acids 734 to 768 are the cytoplasmic domain of the rat P-selectin. http://www.uniprot.org/uniprot/P98106 We do have however two other antibodies against P-selectin which have been tested successfully to recognize the cell surface P-selectin, ab54427 and ab54426, as they work in flow cytometry without permeabilization. |
