DNALC Making Lactose-Free Milk Kit

(in stock)


Beginning—Easy to perform; requires little or no prior knowledge.

  • Developed in partnership with the DNA Learning Center
  • Creates real-world connections between lactose intolerance, evolution, and enzyme functionality
  • Uses engaging technique to create lactase enzyme, sodium alginate beads

Many students are aware of lactose intolerance, but how many actually understand what it means and how it relates to human evolution? Help your students make that connection with this exclusive kit from Carolina and the DNA Learning Center. Students review the relationship between genes and proteins, learn about enzyme functionality, and explore the relationship between lactase and human evolution. In the core activity, students create a column with immobilized lactase enzyme beads to create lactose-free milk. Designed for 8 groups of students working in groups of 2 to 4 and can be completed in a 50-minute class period.
