Figure 9. Quantitative data of real-time reverse transcription polymerase chain reaction (RT-PCR) for glial fibrillary acidic protein (GFAP) and syntaxin 1. A relative RNA ratio was calculated by dividing the value of each purification method by the value of whole retinal cell suspension. Data were expressed as the mean±SEM. (n=9 for each method). The p value for GFAP and syntaxin 1 was 0.021* and 0.022**, respectively.
