Calculating PFA Diffusion Rate in 1% Agar Gel: Tips and Resources

[harryfeng]

Hi:

I am doing a research project in which I need to diffuse PFA(Paraformaldehyde) into agar gel. I want to know how to calculate the diffusion rate. The agar gel is 1%, and 2 mm thickness. How long approximately does it take for PFA to diffuse from the top to the bottom?

Is there any article that I can read about?

Thanks

Umm... this is *your* research project, right?

What do you propose to measure?
