Figure Set 1: Evidence for Brazil Nut Allergen in Transgenic Soybeans

Purpose: To show that allergens can be transferred from one plant to another through crop biotechnology and, thus, may pose a food safety issue
Teaching Approach: "pairs share"
Cognitive Skills: (see Bloom's Taxonomy) — comprehension, analysis, evaluation
Student Assessment: minute paper

Figure 1. Results of Radioallergosorbent Assays with Extracts of Non-transgenic Soybean (triangle), Transgenic Soybean (square), and Brazil Nut (circle). Concentration of 2S albumin (in nanograms, log scale) in each dilution of extract in relation to percent inhibition of IgE binding (see Student Instructions for further description of axes) (from Nordlee et al. 1996. Identification of a Brazil-nut allergen in transgenic soybeans. The New England Journal of Medicine 334: 688-692).
