Figure 6. Biochemical characterization of PKM2 and PKM1 isoforms on isolated cone photoreceptor cells from Nrl−/− mice.

Figure 6

Retinal homogenates from Nrl−/− mice were subjected to OptiPrep™ (8–40%) density gradient centrifugation, and fractions of inner segments and intact photoreceptors (A) were collected from the top to the bottom of the gradients. A ten-microliter sample (three-microliter for M-opsin) was subjected to immunoblot analysis (B) with M-opsin, α-3 Na/K ATPase, pPKM2, PKM2, and PKM1 antibodies. Full-length blots are presented in the Supplementary Information.
