Calculate kDa - (Jan/17/2005 )

How can I calculate the mass (kDa) of a Protein. Is it possible via the sequence?


yes, this is possible. most programs will do that. I personally know that "seqman" and "generunner" have this feature buildt in, and I think many other commonly available programms will do that, too.



I use an online program called 'protparam' at
Just plug in the exact amino acid sequence of your protein and it'll spit out all sorts of useful info about the protein.
