Exploration of the Visual System: Part 1: Dissection of the XXXX Eye for RNA, Protein, and Histological Analyses.

@entity19 @entity267 @entity989
Due to the power of genetics, the @entity19 has become a widely used animal model in vision research. However, its eyeball has an axial length of only about 2 mm. The present protocol describes how to easily dissect the small rodent eye post mortem. This allows collecting different tissues of the eye, i.e., @entity267 , lens, iris, retina, optic nerve, @entity989 ( @entity989 ), and sclera. We further describe in detail how to process these eye samples in order to obtain high-quality RNA for RNA expression profiling studies. Depending on the eye tissue to be analyzed, we present appropriate lysis buffers to prepare total protein lysates for immunoblot and immuno-precipitation analyses. Fixation, inclusion, embedding, and cryosectioning of the globe for routine histological analyses (HE staining, DAPI staining, immunohistochemistry, in situ hybridization) is further presented. These basic protocols should allow novice investigators to obtain eye tissue samples rapidly for their experiments. Curr. Protoc. @entity19 Biol. 1:445-462    2011 by John Wiley _ Sons, Inc.
