(J) B-wave quantification shows significant decline in scotopic response in Lamp2a -/- mice relative to age-matched WT (n=8 mice/group). (K) Representative maximal response of 6-7-month-old WT and Lamp2a -/- mice. (L) b-wave amplitude quantification shows decreased scotopic response in 6-7-month-old Lamp2a -/- mice relative to age-matched WT (n=6 mice/group). (M) Representative maximal response of 10-12 months old WT and Lamp2a -/- mice. (N) b-wave amplitude quantification shows significant decrease in scotopic response in 10-12-month-old Lamp2a -/- mice relative to age-matched wild type (n=8 mice/group). (O) Representative photopic response of 6-7-month-old WT and Lamp2a -/- mice. (P) b-wave amplitude quantification shows photopic response changes in 6-7-month-old Lamp2a -/- mice relative to age-matched WT (n=6 mice/group). (Q) Representative photopic response of 10-12-month-old WT and Lamp2a -/- mice. (R) b-wave amplitude quantification shows pronounced decrease in photopic response in 10-12-month-old Lamp2a -/- mice relative to age-matched WT (n=8 mice/group). Statistical differences were analyzed using an unpaired two-tailed student’s t-test. Level of significance was considered at p value < 0.05 .

Article Snippet: Adult male Lamp2a knockout mice ( Lamp2a y/- ), female heterozygous Lamp2a +/- and their wild type (WT) littermates ( Lamp2a y/+ ) were obtained from Cyagen (Serial Number KOCMP-16784-Lamp2-B6J-VA; strain C57BL/6J-Lamp2 em1Cya ).
