Abstract
|
|
|
|
Presence of dextran produces problems in sugar production, resulting in sucrose loss and slowing the process. Dextran measurement requires detection of a small amount of dextrans against a background of large quantities of other carbohydrates. Most techniques determine dextran after separation of dextran from background carbohydrates, primarily by alcohol precipitation. The only antibody-based method, Midland SucroTest^(TM) uses a monoclonal antibody. It is rapid, specific, and does not require prior dextran separation, but high cost per analysis for bulk screening of delivered sugarcane. Phage display technology was used to extend analytical options for dextran analysis, in a search for low cost, dextran-specific analytical method that can be used for routine screening of sugar cane.
