PCR-Based VNTR Human DNA Typing
Advanced DNA analysis techniques in an easy-to-use kit! Polymorphic DNA are chromosomal regions of DNA that vary widely between indi- viduals. So-called Variable Number of Tandem Repeats (VNTR) regions vary in length from 15–70 base pairs and may be repeated anywhere from 5 to 100 times on a single chromosome. Since every individual has two copies of each chromosome—one from each parent—the VNTR region may be homozygous or heterozygous for both length and numbers of repeats. In this experiment, students isolate their own DNA for analysis, amplify the VNTR region using polymerase chain reaction (PCR), and then separate the fragments of DNA using agarose gel elec- trophoresis. Students directly observe their own genotype and compare patterns or trends with those of their classmates. A complete review of modern biotechnology principles and procedures in one activity!
Complete for 25 students working in groups of three. A thermal cycler or three water baths, balance, microcentrifuge, and electrophoresis equipment are required but not supplied with this kit. Live material redemption coupon included to obtain live material. Please allow 2–3 weeks to receive live material after sending in the redemption coupon.

Flinn Economy Electrophoresis Kit
By: John Fedors
Biology Teacher—Retired, San Diego, CA
Budget tight? This low-cost do-it-yourself kit allows
you to quickly assemble your own gel electrophoresis apparatus that is guaranteed to perform like the more expensive units. Its easy-to-use design is perfect for the first-time electrophoresis user. This apparatus was teacher-designed and developed and has been thoroughly class- room tested. This innovative instrument operates on batteries and is actually safer than models using power supplies. Best of all, you save money by not having to purchase expensive power supplies.
Kit contains detailed instructions and materials necessary to construct the apparatus. Electrophoresis chemicals, aquarium sealer, and batteries are not included. Requires three to five 9-volt batteries for operation.

Microscopes and Stereoscopes
Flinn Scientific developed this line of microscopes to give you all the most popular features at every price point. What used to be superior is now standard with Flinn microscopes and stereoscopes!
• All Flinn microscopes have achromatic eyepieces and objective lenses and condensers to increase resolution.
• 40X and 100X objectives all retract to prevent damage to the slide or objective.
• LED illumination is standard and most of the scopes are rechargeable.
• A digital option is available for both the Economy and Advanced lines.
Equip your students with high-quality Flinn microscopes and stereoscopes!
