Versuchsvorschrift

One mg of HIgG (Human IgG) dissolved in 0.4 ml of 0.1 M phosphate buffer pH 7.5, was brought to pH 9.5 with crystalline Na2CO3. A solution (10 μl) of FITC (70 μg) in acetone was added with stirring and mixed for 3 hrs at room temperature. The resulting solution was separated two times on Sephadex G-25 (M) column (1×15 cm) equilibrated with 0.05 M phosphate buffer pH 8.0. The eluted FITC-hIgG conjugate solution was 0.58 mg/ml in concentration and had D/P=5.5 (M/M) as determined by the Wells' nomograph.
