I am doing perfusion on mice almost every week. I believe 4% PFA can be stored in fridge for long term. I wonder if it is ok to store diluted heparin (in PBS) in fridge as well?
Many thanks. This article seems to only studied for heparin activity for 24 hours, and it is stable to keep diluted heparin in plastic. I am still confused if it is ok to keep it for a week or more.
