Figure 1. Free glutamate, glutamine, taurine, and glycine levels in rd1 and control retinas during the degeneration process
Free amino acids were measured in rd1 and control retinas at PN4, PN8, PN15, PN21, and PN35 using an amino acid analyzer. The concentrations of each amino acid are expressed as a percentage with respect to the sum of all the concentrations of the amino acids quantified by the analyzer. Bars represent the mean (3 for each age and strain); the error bars represent the standard error of the mean. A: Glutamate. B: Glutamine. C: Taurine. D: Glycine.
