&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;Dissolve pullulan in DMSO, stire for 0.5 hour.&lt;br /&gt;
&lt;br /&gt;
Add 6 mM discuccinmidyl carbonate while stirring&lt;br /&gt;
&lt;br /&gt;
Add 6 mM dimethylaminopyridine&amp;amp;nbsp;while stirring&lt;br /&gt;
&lt;br /&gt;
React at RT (25 oC) for 5 hour.&lt;br /&gt;
&lt;br /&gt;
Cool to 4 oC&lt;br /&gt;
&lt;br /&gt;
add PEI in weight ratios 1:0.25 (PEI is 0.25).&lt;br /&gt;
&lt;br /&gt;
React o/n (16 hours)&lt;br /&gt;
&lt;br /&gt;
Precipitate PEI-Pullulan using acetone.&lt;br /&gt;
&lt;br /&gt;
Wash 5 times with acetone to remove unreacted PEI&lt;br /&gt;
