Co localiza tion of TRIF and IBA1 were examined under a confocal microscope. For retinal flat mounts, eyes were removed and post fixed in 4% PFA for 30 minutes. Retinas from the intact right eyes of the same animals were used as normal con trols. After three washes in PBS, retinas were blocked and permeabilized using 5% goat often serum and 0. 2% Triton X 100 for 1 hour at 25 C, and then incubated with CD11b and a bIII tubulin anti body for 2 days at 4 C. The next day, retinas were rinsed with PBS, then incubated with a goat anti rabbit Alexa Fluor 568 sec ondary antibody at 4 C overnight, rinsed again, and overlaid with a coverslip in mounting medium. Cells were fixed with 4% PFA at 25 C for 30 minutes, then blocked with 5% bovine serum albumin for 30 minutes at 25 C.

The cells were incubated with primary antibody for 1 hour at 25 C, followed by over night incubation at 4 C. The next day, cells were exposed to secondary antibody, 2 mg?mL, Invitro gen for 1 hour at 25 C. Axon outgrowth was evaluated in quadruplicate samples in a blinded fashion, and all experiments were repeated Inhibitors,Modulators,Libraries at least three times, independently. Retinal ganglion cell axon retrograde labeling WT and trif male mice were anesthetized and placed in a stereotactic apparatus. The skull was exposed and cleaned with 3% hydrogen peroxide. A hole 1 mm in diameter was drilled in the skull, and a 26 gauge stainless steel cannula was inserted for infusion of a fluorochrome, hydroxystilba midine infusion. One week before ON lesion.

1 ul of 4% Fluorogold was Inhibitors,Modulators,Libraries injected into the bilateral superior colliculus Analysis of axon regeneration and Fluorogold labeled retinal ganglion cells Analysis of axon regeneration Inhibitors,Modulators,Libraries and RGC survival were conducted in accordance with a previous report. Briefly, regenerating axons Inhibitors,Modulators,Libraries were examined using a cali brated ocular to measure distance in five longitudinal sections of the ON by GAP43 immunostaining, 8 to 10 sections per animal were used in the quantification. A researcher blinded to the sample identity quantified axon growth by counting the total number of GAP43 positive axons arising from RGCs at various distances past the lesion site. The calculation of axon quantification was conducted in accordance with the method of Yin. Axon counts were converted into axon crossings, and the mean Inhibitors,Modulators,Libraries over the five sections was calculated.

��ad, defined as the total number of axons extending distance d in a optic nerve with a radius of r, was estimated by summing over all sections of thickness t as follows, Total Z-VAD-FMK purchase axon number was calculated in each case. Ana lysis of variance was used to test the signifi cance of the differences between groups. To analyze the survival number of RGCs in whole retinas labeled with FG at 0, 1, 3, and 7 day post crush, the gold dots were counted using Image Pro Plus.
