Positive sample negative sample 5. Unbound labeled antibody is washed away and a colorimetric substrate is added. Draw this Positive sample negative sample 6. The enzyme cleaves the substrate causing a color change of the substrate solution. The intensity the color is quantified using a spectrophotometer and is proportional to the amount of antibody present in the sample. (Obviously, a standard curve would have to be generated. Could you think how to do that?). Positive sample negative sample

Standard 7a Rodents can make vocalizations that humans can hear, such as a squeal. But they also can communicate during social interactions using ultrasonic vocalizations - vocalizations at a frequency higher than the human ear is capable of hearing. Sex differences in vocal communication, similar to observations in songbirds, are observed In rats, with adult male rats eliciting a typical type of ultrasonic vocalizations not observed in females. As noted elsewhere in this Problem Set, FOXP2 is involved in the development and neural control of vocalizations in a broad spectrum of species, including rodents. In humans it is linked to human speech and language disorders. In rats, FOXP2 has been related to sex-specific vocalizations, like the male-typical ultrasonic vocalizations. FOXP2 expression in neurons in the brain is greater in males than females. Further, recent research demonstrated that FOXP2 is a target of activated androgen receptors (Le specialize receptors that bind androgens…
