From SDMRC
Materials
- A flash drive
- A tube rack
- Sheet protectors
- PICO developing solution
- 15 ml tube
- Ethanol + KimWipes towels
Method
- After the 1 hour secondary time has passed take your membranes into trays of TBST to wash three times for 10 minutes
- Cut new sheet protector for your membranes (they can be in one protector)
- Take your pico developing solutions (two bottles on bench: brown and clear) with a 15 ml tube, a pipette, and a tube rack to the scanner
- Quickly take your membranes into the plastic (dry a little) and bring to the scanner
- AT THE SCANNER mix the brown and white solution in the 15 ml tube and flush
- The developing solution is 1:1 so divide the total amount needed by 2
Example: 4.5 ml total so 2.25 ml of brown and 2.25 ml of clear
