Fig. 3From: Putative trehalose biosynthesis proteins function as differential floridoside-6-phosphate synthases to participate in the abiotic stress response in the red alga Pyropia haitanensisAnalysis of the reaction products of the in vitro translation of the TPS domain from PhTPS1–4 of P. haitanensis using the E. coli BL21 cells expression system by SDS-PAGE. a Coomassie-stained gel. The arrows indicate proteins of the expected size for PhTPS1–4 (lane M, Maker; lane 1–4, PhTPS1–4, lane 5, negative control, with empty pET-28a or pET-28a-sumo vector). b Translated proteins were analyzed by western blot using a His-tag-specific antibodyBack to article page
