Editing Assay (section)

===Sample type and method===
Depending on the general substrate on which the assay principle is applied:
#'''Bioassay''': when the response is biological activity of live objects. Examples include
##''in vivo'', whole organism (e.g. mouse or other subject injected with a drug)
##''ex vivo'' body part (e.g. leg of a frog)
##''ex vivo'' organ (e.g. heart of a dog)
##''ex vivo'' part of an organ (e.g. a segment of an intestine).
##tissue (e.g. limulus lysate)
##cell (e.g. platelets)
#'''[[Ligand binding assay]]''' when a ligand (usually a small molecule) binds a receptor (usually a large protein).
#'''[[Immunoassay]]''' when the response is an antigen antibody binding type reaction.
