a Signal obtained from incubation of the capture and detection oligo's without RNA

b The expression of each MIR in each tissue was measured in duplicates. Difference between duplicates was ∼5%–10%. The average of the duplicates is presented

c The ratio between the signal value and the Blank value

d Match between the mirMASA, Northern blot (NB), and DNA chip (CH) data. (+) A match (–) no match

e M is short for match. For the thymus, testes, and placenta, no Northern blot data is available, and comparison was done only to DNA chip data
