Don't know if this'll work - but may be worth a shot. It's what I used for 
acutely dissociated retinal neurons from turtle.

Original Ref: 

Le Dain, A.C., Anderton, P.J., Martin, D.K., Millar, T.J. (1994) J. Membrane 
Biol. 141, 239-245.

Tissue pieces incubated in incubation solution containing 15U/mL papain and 
2.5mM cysteine. Following 30min @ RT preincubation of enzyme soln, tissue 
pieces added on oscillating (2Hz) culture dish for 45min @ RT. Pieces 
transferred to recording soln and triturated through very narrow bore pastuer 
pipette (fire-polished). Stored at 6 deg for max 6 hours.

Incubation soln (mM) 120 NaCl, 2.5 KCl, 0.5 MgCl2, 0.5 MgSO4, 2.5 CaCl2, 1.0 
NaHCO3 0.5 NaH2PO4, 16 glucose, 4.0 HEPES, 0.02mg/ml BovineSerumAlbumin. 
pH7.6 (NaOH)

Recording soln (mM) 125 NaCl, 3 KCl, 2 CaCl2, 1 MgCl2, 6 NaHCO3, 0.5 NaH2PO4, 
pH7.4 (NaOH)

Cells plated in chamber dish (plastic) precoated with 0.25/mL concanavalin A.
(60min with at least three H20 washes to remove excess - then allowed to 
air dry).
