Well, this is pretty basic chemistry!
moles = (mass in grams)/MW.
pmol = pg/MW, so pg = pmol x MW.
MW is about 21,000 daltons (unglycosylated), so 1 pmol/L = 21,000 pg/L =
So, multiply the number of pmol/L by 21 and you have pg/mL.
IL-1 MW = 17kDa. TNF MW = 17kDa (secreted form, not membrane bound).
You do the maths!
