Pigment composition of the Suc gradient bands containing Lhcs
Carotenoid concentrations are normalized to 100 Chl molecules to facilitate comparison of different samples. Carotenes were not detected in these bands (nd). Pigment composition of band 3 from Arabidopsis is also shown for comparison. sd < ±10%.
