Intraocular injections: 

Syrian golden hamsters (Charles River Laboratories) are born with a premature visual nervous system (Clancy et al., 2001). These mammals were used for studies investigating the implication of GPR55 ligands during retinal ganglion cell projection growth during development in vivo. Twenty-four hours following birth, at P1, anesthetized hamsters received a unilateral intraocular injection of 2 l solution of CTb, with either 0.9% saline solution, 1 mm of LPI or 300 m of CBD. … For eye-specific segregation studies in the dLGN, gpr55-/- and gpr55+/+ adult mice received an intraocular injection of CTb conjugated to AlexaFluor 555 into the left eye and CTb coupled to AlexaFluor 488 into the right eye (2 l; 0.5% in sterile saline). …

The effects of the intraocular injection of GPR55 agonist and antagonist were visualized by immunohistochemistry according to a protocol previously described in (Argaw et al., 2008). Briefly, 40 m thick coronal sections of tissue were incubated in 90% methanol and 0.3% H2O2 in 0.1 m PBS, pH 7.4, for 20 min. They were then rinsed and incubated in 0.1 m glycine/PBS for 30 min, followed by an overnight incubation (4C) in PBS containing 4% NDS, 2.5% BSA, and 1% Triton X-100. The sections were subsequently rinsed and immersed for 48 h at room temperature in a solution containing goat anti-CTb diluted 1:4,000 in PBS with 2% NDS, 2.5% BSA, and 2% Triton X-100.
