(APTES)3-Aminopropyltriethoxysilane is a silylation agent used to treat glass slides and create a reactive film (primary Amines). Treated surface can be used to crosslink and immobilize proteins and other molecules.
APTES is used to treat the glass slide before mounting tissue sections during immunohistochemistry (IHC).


1. Dilute (APTES)3-Aminopropyltriethoxysilane 1:50 with acetone in a plastic beaker.

2. Fully coat clean slides with diluted (APTES)3-Aminopropyltriethoxysilane solution. A rack at a time and incubate for 2 minutes at room temperature.

3. Wash the slides with distilled water 1-2 times.

4. Aspirate the (APTES)3-Aminopropyltriethoxysilane solution, drain slides and dry in 60°C oven for 1 hour.


1. Dilute (APTES)3-Aminopropyltriethoxysilane should be freshly prepared before use.

2. There will be a small amount of milk-white substance on the slide after coating.
