A judicious choice of photoreactive group is critical in successful photoaffinity labeling studies of small molecule-protein interactions. A set of carbohydrate-based photoaffinity probes was prepared to compare the effects of three major photoreactive groups on the efficiency and selectivity of crosslinking a binding protein with low affinity. We showed(More)
Attachment formation is the most pivotal factor for humans and animals in the growth and development of social relationships. However, the developmental processes of attachment formation mediated by sensory-motor, emotional, and cognitive integration remain obscure. Here we developed an animal model to understand the types of social interactions that lead(More)
PHOTO OPPORTUNITY: We have developed a dual photoaffinity labeling system in which an active and an inactive probe bearing orthogonal detection groups are co-reacted in a single photoreaction. The approach allowed selective fluorescent detection of a model binding protein in cell lysate by either 1D or 2D electrophoresis.
Photoaffinity labeling has been used as a promising approach to detection and isolation of carbohydrate-binding proteins, which are typically characterized by low binding affinity and selectivity. When there are several specific binding proteins, it is desirable that a photoaffinity probe is capable of simultaneously crosslinking them and that the(More)
