Immobilization of Lactase Enzyme on Alginate Beads - A Quick Test

Andrea Amato | Mon, 01/07/2019 - 18:18

I came across an interesting Journal of Chemical Education article that explains how it is possible to crosslink sodium alginate, leading to the formation of calcium alginate beads. Calcium alginate beads are hydrogels and one of their uses is to immobilize enzymes in their structure. I thought it would be cool to immobilize some lactase enzyme onto calcium alginate beads and investigate its ability to hydrolyze lactose.

Review Lab - Better than a Worksheet

It can be difficult to engage students in reviewing for semester exams by using worksheets or practicing problems on the whiteboard. If you are looking to change up your review plans, you might consider using a lab activity that provides opportunity to revisit many of the topics that need to be covered.
