Gel Electrophoresis (Horizon) Kit

Students explore how to use biotechnology equipment, how to micropipette, and how to perform gel electrophoresis, analyzing various samples from dyes to DNA.

Kit Description

The Gel Kit contains 8 Horizon gel electrophoresis boxes, 4 power supplies, 2 microcentrifuges, a complete set of 32 micropipettes, 8 of each volume range. It also comes with all the reagents and consumables needed for students to explore micropipetting and gel electrophoresis. 

  • SEP has 12 Horizon Gel Electrophoresis Kits
  • Each Gel Kit has 3 crates and a freezer box for DNA and reagents
  • Labs are designed for 8 groups of 4 (32 students total). Make sure to tell us if your class is significantly larger in size
  • SEP teachers who have their own equipment may request to receive supplies only

Curriculum and Units Supported by the Gel Kit

Intro to Micropipetting

In this lesson, students are introduced to micropipetting. They will explore how a micropipette works, what the various ranges of different micropipettes are, how to read and adjust the volume, and how to properly use a micropipette.

Electrophoresis Exploration

In this lesson, students learn about the equipment used in  gel electrophoresis and the chemical properties behind its function. Through this inquiry lab, they will learn about the concepts of conductivity, pH, and buffer chemistry.

Dye Electrophoresis Lab

In this lesson, students learn about dye chemistry and how to separate complex mixtures of molecules by size, shape, and charge using gel electrophoresis analysis.

Precut DNA Lab

In this lesson, students connect concepts about DNA and enzymes by running gel electrophoresis analysis on pre-cut DNA and observing different banding patterns created by different enzymes.

Molecular Scissors

In this lesson, students will use restriction enzymes to cut DNA at specific locations. Students perform their own restriction enzyme digests and analyze the resulting banding patterns in their gels.

Elephant Ivory Cache Unit

Explore how to integrate ecology, ethics, and biotechnology into a biology classroom by using current research on African elephant conservation. Students have opportunities for evidence-based argumentation as they collectively determine the source of poached ivory through a DNA lab experience.

DNA Exoneration

This unit uses multiple DNA exoneration case studies as a way for students to explore modern day forensics, the criminal justice system, and mass incarceration in the U.S.

Elephants and Cancer

Carry out an investigation using gel electrophoresis and bioinformatics to determine the presence/absence and relative quantity of TP53 in multiple animals. This is Lesson 2 in the Elephants and Cancer Lesson Sequence.

HLA Typing

In this lab from Lessson 7 of the Frontiers: Intro to Cancer Unit students students use DNA technology to find Hina a match for a bone marrow transplantation.

COVID-19 Molecular Testing Lab

Examine patient samples after performing gel electrophoresis analysis to determine if their patient is positive, negative, or inconclusive for COVID-19 infections based on the RT-PCR method tests that detect the SARS-CoV-2 virus. This lab is from Lesson 2 of the COVID-19 Testing Lessons.

How to Pack Crates

Yes, Gel Kit crates can be a pain in the . . . But! There's hope. Here are three guides, one for each crate. If items just aren't behaving, it's better to put them in a separate container (box, grocery bag) and bring them in that way. We would rather have them returned separate and intact, rather than together, smooshed and broken.
