to differentiate between 2 proteins

[Koen Peeters]

Dear,

I need a solution to the following problem : I have a Fab fragment with
and without C-terminal
DIKDEL aminoacids produced in plants. I need to know wether the
C-terminal DIKDEL
are present or cleaved in planta.

Is there any molecular technique that I could apply that will
differentiate the presence
of these 6 C-terminal aminoacids?

No antibodies against DIKDEL/KDEL are working on Western blot.

Thanks

Koen
