Hi Timor

We use 0.1% trypsin in PBS or TBS at 37'C for 15 mins. However, you may
change times and temperatures to suit a particular antibody signal. We
sometimes incorporate calcium chloride in our trypsin buffer ( same
concentration as the trypsin); aids digestion for certain antibodies to
work optimally. There are a few enzymes worth rying when optimising; Ficin,
Pronase, Proteinase K etc... They all have different digestion strenghs.
Have fun .
