physiologigal buffers at pH 2-5?

[Mathias Holpert]

Hi all,

I'd like to do some acid resistance studies on Toxoplasma gondii and would
need a suitable buffer system that is buffering at around pH 2 to 5 to
incubate my parasites for 30 min max (room temperature). Of course, this
buffer would have to be physiological as I don't want to disrupt them right
away. Any suggestions?
