[bionet.molbio.proteins] Determination of Protein pI?

ABELSON.WESTAWAY@BIONET-20.BIO.NET (SHAWN WESTAWAY) (07/06/88)

Does anyone out there know of a simple and fast method for the
experimental determination of an already purified protein's
isoelectric point, without buying or constructing unusual PAGE
apparatus?  Most of the recent methods I have seen apply to
separating similar proteins away from each other, and involve
construction of different apparatuses, or purchase of buffer
gradient chemicals.  Also, can the pI of a protein be determined
under native conditions, or must it be denatured during the process?

Thanks, reply to ABELSON.WESTAWAY, c/o BIONET-20.ARPA
