CP in sample solutions was reacted with anti-CP rabbit polyclonal antibody immobilized in a 96-well microtiter plate and sandwiched with horseradish peroxidase-conjugated lectin, followed by color development by the enzyme activities. Using standard chitosan solutions, a good standard curve (R2=0.977) was established between 0 and 250 ¦Ìg l-1 with the average coefficient of variation of 7.0%, and CP in the diluted culture supernatants could be directly determined. This method can apply for the direct determination of other polysaccharides in solution by selecting an inexpensive custom-made polyclonal antibody and an appropriate lectin, both of which may be commercially available %K n/a %U https://scidoc.org/IJBMBS-2470-4490-04-101.php
