Abstract
Protocol for MTT cytotoxicity assay on SH-SY5Y cells.
Steps
General

6.
Add in protein solutions
7.
Place back at 37 °C and 5% CO2 for 24 h
Day 3
8.
Dilute MTT 1:10 in RPMI medium
9.
Aspirate medium from cells
10.
Add 100 µL MTT/RPMI solution per well
11.
Place back at 37 °C and 5% CO2 for 4 h
12.
Aspirate medium from cells
13.
