실험 절차
10 mg of carboxy-modified carriers were washed twice with 1 ml of acetonitrile (MeCN) and then taken up in 1 ml of MeCN. To this were added 10 mmol of dicyclohexylcarbodiimide and 10 μmol of N-hydroxysuccinimide. This was followed by shaking at room temperature for two hours. Washing was then carried out once with 1 ml of cyclohexane and once with 1 ml of MeCN. The particles were then taken up in 1 ml of MeCN. 4 μmol of N,N-biscarboxymethyl-L-lysine were added thereto and shaken at room temperature for three hours. This was followed by washing once with 1 ml of acetonitrile and twice with 1 ml of 10 mM phosphate buffer (pH 7.0).
