 were prepared in 0% NDS, 0% BSA, 0.0% TritonX-000, 0.00% NaN~0~ in 0x PBS. After incubation, retinas were washed three times for 00 min in 0x PBS with 0.0% TritonX-000 before being transferred into the secondary antibody solution (Alexa000 donkey anti-rabbit (Invitrogen, A00000, 0:000) and Alexa000 donkey anti-goat (Invitrogen A-00000, 0:000); prepared in 0% NDS, 0% BSA, 0.0% TritonX-000, 0.00% NaN~0~ in 0x PBS. Retinas were then washed three times in 0x PBS with 0.0% TritonX-000 and once in 0x PBS. Mounting procedures are the same as listed above.
