3.1.Ⅰ. Extent of chemical modification
Figure 21 shows the percentage of chemical modification of lysyl residues in albumin protein (AP)
with EDTAD. The experimental work was shown, the extent of modification increase with rising
amount of EDTAD to protein ratio (w/w %). For AP, the protein to EDTAD ratio of 1: 0.2 was
sufficient to modify 90% of the lysyl residues. The various protein sources with different amounts
of lysyl content may be required different amounts of EDTAD.
