Illustration of a nomenclature system

Reagent	Nomenclature	Legend
RNA Transcript	ERCC-nnnnn-vv	nnnnn = unique 5-digit sequence number vv = 2 digit version number
PCR primer/probe microarray probe	ERCC-nnnnn-vv- pppp-lll-aaa	pppp = 4-digit positional location relative to the 0th base at the 5' end of the transcript sequence lll = primer/probe length aaa = nucleic acid sequence of the initial triplet of the primer/probe (complement of the RNA sequence at pppp, pppp+1, pppp+2)
