Added probes at 1 ng/µL concentration.

Washes, incubated with the blocking for 1h and at 4 °C overnight with the respective antibodies. Anti-DIG-AP 1:5000 for all Novocrania wells and Anti-DIG-POD 1:250 for all Terebratalia wells.

Washed antibody from all samples with:
- 5x 15 min PBT and 5x 30 min PTw.
- 3x 5min washes of AP minus MgCl2 for regular in situ and TNT buffer for fluorescent in situs.
Developed fluorescent wells with TSA kit using cy3 fluorochrome for 2 hours. Sropped the reaction with 5x 5 min detergent solution at 60°C followed by PTw washes. POD inactivation with 0.1% H2O2 for 45 min, PTw washes, and finally formamide based POD inactivation buffer for 15 min at 60 °C. Signal for pax6 and delta were very strong, pou4 was strong and pax258 was medium.
I started developing Novocrania with NBT/BCIP. Pax6 was the first to come, strongly. The others were slower, but gli had a good signal/noise ratio. Others acquired background after the first AP change after 2 hours. I stopped all, except delta and smo2 (which had less background).

Today they were quite dark :/
Went through ethanol washes and antibody washes for fluorescent. Added 70% glycerol in PTw with 1:10000 sytox green.
