Q: If our gene belongs to the hormone receptor and I purify the protein of this gene. Can anyone tell me how can I confirm this protein by binding commercially available hormone else Wb(western bloat)and IFA(Immuno Flouresecent Assay)?

Because i confirm the protein of this specific hormone receptor by agonist or antagonist.

Anyone known the knowledge about any commercially available kit of hormone for conformation of specific protein receptors?

For example :If i check the protein of a specific gene of estrogen hormone or progesterone hormone receptor.
