 **DAY 1:**
-Step 1: Gather desired slides into a 4x6 well plate. Cut a transfer pipette to allow wider width and use this to collect slides and anti-freeze from storage well plates to working well plate. Have two wells designated as controls, one without primary antibody, one without secondary antibody.

+  - Wash slides in TBST for 10 min, 3 times on agitator (room temp.). Remove the liquid from each well with a thinned transfer pipette and then fill the wells around half way (~1ml) with TBST.

+  - Block in TBST + NDS (1ml/well) for 60 min on agitator in fridge.
+  - While waiting for block, prepare primary antibody. c-Fos antibody 1/8000 concentration in TBST + NDS (1/8000 = 0.125μl of primary in 1ml of TBST + NDS. //Example:// 36 wells = 0.125μl * 36 = 4.5μl of primary + (36000μl – 4.5μl) 35995.5μl of TBST + NDS = TOTAL volume of 36000μl (36ml).

-NOTE: Alexa 488 is light-sensitive, prepare solutions in dark and hold in a falcon tube covered in aluminium foil.
+  - Fill a flat circular dish with TBS and transfer the desired slides (one well at a time) into the container. From there, mount slides onto a gelled microscope slide. Add Fluromount-G+DAPI (kept in fridge – about 1 drop per tissue section) and then place a coverslip on top. Allow slide to dry in a dark place. When ready, place slides in slide holder and store in fridge until imaging.
