I just discovered that this site says, "ELISpot assays employ the sandwich enzyme-linked immunosorbent assay (ELISA) technique." That is not very accurate. To be sure, there are some undeniable similarities between the ELISPOT method and the ELISA assay technique, but it's a bit of a misrepresentation to say that the former uses the latter. I would certainly be extremely uncomfortable making such a claim.
Yeargh.
