The conversion
- 1 pg/mL = 0.1182 pmol/LFrom pg/mL to pmol/L: divide by 8.457. Back again: multiply by 8.457.
pg/mL and ng/L give the same number.
Mass and molar units are linked by the molecular weight: 8,457 g/mol (NT-proBNP, the 76-amino-acid N-terminal fragment of proBNP (residues 27-102 of UniProt P16860). Average mass calculated from that sequence is 8,457.5 g/mol, so 1 pmol/L = 8.457 pg/mL.). Source: UniProt.
Common values
From zero to about twice the usual upper limit, plus the usual limits themselves.
