  • Product overview

    Abcam's Starch Assay Kit provides an easy, accurate assay to measure starch levels in a variety of samples. In the assay, starch is hydrolyzed to glucose which is oxidized to generate color (570 nm) and fluorescence (Ex/Em = 535/587 nm). The assay can detect starch at 0.0004 to 2 mg/ml.
    Visit our FAQs page for tips and troubleshooting.

  • Notes

    Starch is a complex carbohydrate consisting of a large number of glucose units. All plants contain starch, present as amylose, (linear a-1,4 linked polymer) and amylopectin, (highly a-1,6 branched a-1,4 polymer). Starch generally contains 0-25% amylose and 75-100% amylopectin.
