Investigate cancer in the laboratory. Students safely explore aspects of cancerous cell growth with this totally self-contained kit. (A fresh carrot will be required.) Experiments enable students to visualize the differences between normal cells and cancerous cells, describe similarities and differences between animal and plant cancers, identify cancer cells, identify a plant cancer or gall, and research current theories on the causes of cancer. Students grow their own sunflower plants; then induce crown gall by inoculating plant tissue with Agrobacterium tumefaciens (reply card item ships upon request and only in Continental US) which is required
for inducing the cancerous growth. Students then do a Koch’s Postulates Experiment: Inducing Cancer in Carrot Tissue. Allow 3-4 weeks if growing your own plants prior to innoculation and 3-4 weeks for tumor growth. Experiment requires approximately one hour of lab time. Designed for 24 students. We recommend coordinating your Koch's postulate experiment to use the same Agrobacterium tumefaciens culture or sub-culturing for later use. This kit requires a free USDA permit for handling Agrobacterium tumefaciens to be obtained before the organism can be shipped.
