Figure 1. Gna11 and Gna14 are expressed in ipRGCs, often in combination.

A–E. Representative images of RT-PCR analysis of single ipRGCs for Opn4, Gnaq, Gna11, Gna14, and Gna15. All representative gels show RT-PCR analysis of single ipRGCs taken from P1 Opn4^Cre/+; Z/EG mice. Each lane represents one cell, the positive control is whole retinal RNA, and the negative control is water. F–G Summary of expression of G_q/11 family members in the 16 ipRGCs obtained from P1 and P4 Opn4^Cre/+; Z/EG mice. All cells expressed melanopsin. 15 cells expressed Gna11, 10 of which also expressed Gna14. H. Venn diagram showing the distribution of G_q/11 family member expression in all 32 ipRGCs sampled.
