Coomassie blue stained LiDS polyacrylamide gradient (10-20%) gel of PBS linkers run using a Tris-glycine buffer system (left). A Tris-tricine buffer (right) gave higher band resolution for RCC307 and WH7803. Green dots indicate linker polypeptides fluorescing green under UV light due to the presence of a PUB chromophore. Colored stars indicate the pigment type of each strain (see Figure 1 for color code). FNR: ferredoxin:NADP⁺ oxidoreductase.
