DNALC Making Lactose-Free Milk Kit

Item # 211337 Exclusive This product is exclusive to Carolina Biological Supply.

Looking for an activity that helps your students develop a complete understanding of enzymes, from enzyme-substrate relationships to gene-protein-enzyme connections to human evolution? This kit offers the complete package, while making exemplary real-world connections.



In stock and available to ship.

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.

DNA Learning Center

Cutting Edge Science in your Classroom

Carolina Biological and the Cold Spring Harbor Laboratory's DNA Learning Center (DNALC) have partnered together since 1986 to make molecular genetics and biotechnology more accessible to students globally. Focused on creating innovative classroom activities that give students the opportunity to go hands-on with DNA and explore the core principles of genetics. Together we have constantly worked to increase the accessibility of many key scientific breakthroughs for classrooms globally, including such techniques as PCR, DNA Sequencing, and RNAi.

Bringing a Carolina and DNALC kit into your classroom introduces your students to the experience of scientific research on its highest level, in some cases Nobel Prize winning research, with ease and simplicity. Each kit features in-depth background information, classroom tested protocols, pre-packaged materials, and the knowledgeable technical support of the Carolina Biological team. Our wide selection of kits in this series offers educators' unmatched opportunities to bring biotechnology or genetics into their classroom, with a best in class product.

At Carolina, we believe that innovative research doesn't just belong in a lab—it belongs in your classroom.

About the DNA Learning Center

The DNA Learning Center (DNALC) is the world's first science center devoted entirely to genetics education and is an operating unit of Cold Spring Harbor Laboratory, an important center for molecular genetics research. The mission of the DNA Learning Center is to prepare students and families to thrive in the gene age. We envision a day when all elementary students are exposed to principles of genetics and disease risk; when all high school students have the opportunity to do hands-on experiments with DNA; and when all families have access to genetic information they need to make informed health care choices.
