That was my original thought, too.  However, I then noticed their catalogue
description:  "Epitope mapping at the carboxy terminus of g-PAK p62 of human
origin (identical to corresponding rat sequence)".  I checked more than one
POSTED human sequence against more than one POSTED rat sequence in the
database, and all show that 11 residues from the c-terminus human g-PAK
contains Methionine, whereas rat g-PAK contains Lysine.  If I take Santa
Cruz's description as accurate then the epitope would not be from the
extreme c-terminus.  Maybe it is wrong of me to assume they would not make
such a misprint, or perhaps they have different sequence data that I could
not find.
