Re: silane coated slides

From:Lorraine Gibbs

Hi Kathy-

We use a protocol which calls for a 10 second dip in 2% AAS.
 5 mls of 3-aminopropyltriethoxysilane (Sigma A-3648)
250 mls of pure (99.5%) acetone

We first thoroughly clean and oven-dry slides. Dry slides are dipped in 2%
AAS for 10 seconds, rinsed in deionized H2O 3X, 5 dips each. Air-dry or oven
dry slides. Several racks of slides (up to 400 slides) can be run through
this solution. Slides should be OK at room temperature for at least 6

I don't know if the time in silane is the problem.

Good Luck!
