Safety warnings
Please refer to the Safety Data Sheets (SDS) for safety and environmental hazards.
Before start
Obtain approval to work with human stem cells from an appropriate Institutional Review Board.
mRNA Synthesis
Clone coding sequence of Atoh1 into a vector containing the T7 promoter and poly(A) tail for in vitro transcription.
Clone coding sequence of Ngn2 into a vector containing the T7 promoter and poly(A) tail for in vitro transcription.
Linearize Atoh1 and Ngn2 vectors.
Subject linearized Atoh1 and Ngn2 vectors to mRNA synthesis using the HiScribe T7 ARCA mRNA Kit.
Purify mRNAs using the MEGAclear Transcription Clean‐Up Kit.
Transfect mRNA
Transfect using a cationic lipid (e.g. Stem-In).
For each well of a 12-well plate, incubate 0.25 µg mRNA with 1.5 µL lipid in 50 µL PBS for 00:15:00 .
Add DNA:lipid complexes to cells.
