Transformation of E. coli with pGalTM (Blue Colony)TM
Transformation involves the uptake of extra-cellular DNA by another cell, resulting in a newly acquired genetic trait. In this experiment, the bacterial “transformants” acquire antibiotic resistance and a blue color, following the uptake of a plasmid carrying genes with β-galactosidase and ampicillin resistance. The plasmid used, pGalTM, is unique and designed specifically to simplify the process. Cells provided
are freeze-dried and ready to reconstitute and use—eliminating the need for costly overnight shipping and preparation of competent cells. Transformation and plating of cells requires 50 minutes followed by overnight incubation. Redemption coupon included to obtain live material.

Understanding the Human Genome—Student Laboratory Kit
Students will be excited to learn about heredity, genetics and the human genome as they examine traits on their favorite test subjects—themselves! Common dominant and recessive human traits are explored, some more obvious than others. Widow’s peak vs. straight hairlines are easy to see. Tongue rollers vs. non-tongue rollers and PTC tasters vs. non-PTC tasters will require a little more investigating. Safely teach blood-type inheritance using the simulated blood. Complete for 30 students working in pairs. A Super Value Kit is also available for 5 classes of 30 students.

Antibiotic Sensitivity Testing— Student Laboratory Kit
The purpose of the lab is to expose students to the fundamental procedures used by microbiologists to inoculate, culture and analyze bacterial cultures. After learning basic bacteriological techniques, students determine whether a culture of E. coli is resistant, intermediately sensitive or sensi- tive to a series of five antibiotics. These
are the same techniques originally used in hospital laboratories to determine the most effective treatment for infections. Includes materials for 100 students.

Antibiotic Resistance—Student Laboratory Kit
for more biotechnology
equipment
Students will obtain data by tracking the population of three different strains of bacteria, represented by three different colored bingo chips, throughout the antibiotic treatment. When the antibiotics are taken on time, every time, the bacteria will gradually become elim- inated, from the least resistant to most resistant. However, if a dose (or more) is missed, the bacterial populations will grow. Students will construct a graph of their results and analyze the effects of the antibiotics on three strains having different antibiotic resistance levels.
