(Aminoacyl)n=1-10-AH-Sepharoses can easily be prepared by the N-carboxy anhydride method from amino acid N-carboxy anhydrides and AH-Sepharose 4B at pH 10.2, 0degreesC in aqueous borate buffer. Syntheses of cystinyl-, cysteinyl-, isoleucyl-, leucyl- and phenylalanyl-AH-Sepharoses are described. An improved preparation for cystine bis(N-carboxy anhydride) is presented.
