Models & Assays

Whole body imaging protocols are used for assessing the effects of therapeutics on metabolism and feeding behavior. Using dual energy x-ray absorptiometry (DEXA) body composition can be determined non invasively in longitudinal studies. These studies give body composition in terms of the percentage of fat, lean and bone tissue. Body composition is an important component in obesity studies.
