You now have a putative beta5 receptor-expressing HEK cell line which binds [125I]-X100 specifically.
Discusswhat it means for the receptor to bind a ligandspecifically?
What are the features of specific binding?
How would you experimentally demonstrate, using whole cells, that X-100 specficially bindsthe beta 5 receptor expressed on the cell surface of these HEK cells? (note that this question is worth more than a few points and this is a molecular pharmacology course which requires that you leave the course understanding how binding is measured!!)
