  4. How does Product A3648, (3-Aminopropyl)triethoxysilane, compare to poly-L-lysine for binding tissue to glass surfaces?

    This product has been cited as being a better tissue adhesive than poly-L-lysine. Maddox PH, Jenkins D., 3-Aminopropyltriethoxysilane (APES): a new advance in section adhesion. J Clin Pathol., 40(10):1256-7 (1987).

  5. Can Product A3648, (3-Aminopropyl)triethoxysilane, be used to coat controlled pore glass?

    To coat controlled-pore glass beads for affinity chromatography, the following method is recommended:1. Treat 1 g of clean beads with 20 mL of a 10% aqueous A3648 (pH 3 to 4) at 75 °C for 2 hours.2. Filter the beads to remove the solution and dry overnight in a 115 °C oven. See: J. Dairy Sci., 73, 2720-2730 (1990).

  6. Can I buy glass slides already treated with Product A3648, (3-Aminopropyl)triethoxysilane?

    Yes. Silane Prep slides, Product No. S4651, are produced using A3648. These slides have an expiration period of 24 months.

  7. What is the Department of Transportation shipping information for this product?

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product.

  8. What is the concentration of the (3-Aminopropyl)triethoxysilane, commonly known as APTES?

    The (3-Aminopropyl)triethoxysilane, which is a neat liquid, is 4.3 M. This is based on a density of 0.946 g/mL and a molecular weight of 221.37.

  9. Can the coating made from product A3648, (3-Aminopropyl)triethoxysilane, be removed?

    For Product A3648, (3-Aminopropyl)triethoxysilane, the siliconized coating can be removed by an overnight treatment with 10-20% (w/v) aqueous or alcoholic potassium hydroxide or sodium hydroxide solutions. It may also be possible to remove the coating by physical abrasion, i.e., scrubbing or vigorously brushing the glass surface. Autoclaving will not destroy the coating.
