Cell Culture

[Brian A. Hollander]

In regard to #2 below, we use a PTFE-like material called Aclar, 
originally described as a substrate for culture by Masurovsky and Bunge 
(1968, Stain Tech. 63:161-165). I don't have the exact protocol here at 
home but basically we treat it for a couple of hrs in 100% nitric acid 
followed by H2O washes, then an overnight incubation in 7X detergent, 
and sterilization by incubation in 100% ethanol. The pieces of aclar are 
coated with collagen then poly-l-lysine. At one time Aclar was only 
available from Allied Chemical (as I recall), but I think polysciences 
now sells the stuff. Hope this helps, any questions about a more detailed 
protocol can be put to me by e-mail and I'll try to answer.
