Youare trying to come up with a simple colorimetric test for thedetection of hypersulfated chondroitin sulfate as a contaminant ofheparin sulfate. You have access to
-samples of heparin and/or tainted heparin having equal potenciesas anti-coagulants
-heparinases, enzymes that are specific for the hydrolysis ofheparin sulfate
-copper reagents that turn yellow upon reacting with reducingsugars
Describe how such a colorimetric test might work, specifically addressing how you would detect a sample that has beentainted with chondroitin sulfate.
