Abstract
Protocol for performing ImmPRESS immunostaining with alkaline phosphatase labeling after BaseScope In Situ Hybridization mouse brain sections.
Materials
Reagents: ImmPRESS‱-AP Horse Anti-Rabbit IgG Polymer Detection Kit (MP-5401; Vector Labs) Vector‱ Blue
Alkaline Phosphatase Substrate (SK-5300; Vector Labs)
Troubleshooting
Day 1
Complete BaseScope in situ hybridization using 35um mouse brain sections. Do not dry slides.
Wash slides 2 times in PBS at room temp 5 minutes each wash
Block sections in 0.4% Bovine Serum Albumin (BSA), 10% horse serum, 0.3% triton X-100 for 1 hour at room temp
Incubate sections in rabbit anti TH (1:500) in 0.4% BSA, 5% horse serum and 0.1% tritonX-100 overnight at 4 degrees C
Day 2
Wash slides in PBS at room temp (3 times 5 minutes each wash)
Incubate slides in secondary antibody (ImmPRESS-AP Polymer Reagent) at room temp for 2 hours.
Wash slides in PBS at room temp (3 times 5 minutes each wash)
- Prepare the Alkaline Phosphatase Substrate
a. Make 2.5mL 100mM Tris-HCl, pH 8.2
b. Add 1 drop of Reagent 1
c. Add 1 drop of Reagent 2
d. Add 1 drop of Reagent 3
e. Mix well – use immediately
Incubate sections in alkaline phosphatase substrate for 5 minutes
Wash slides in PBS (2 times 5 min each wash)
Dry slides at 60°C for ≥15min until they are completely dry
Coverslip slides using VectaMount
Store slides at room temp
