That depends on the protein

Add some detergent to your soln: Triton-X-100, Nonidet-P40 or so, less than
1% should be enough

There are solutions of dichlorodimethylsilane available. Fluka (no affil.)
sells a very convenient one in pentane or heptane (that avoids the toxic
trichloroethene that is commonly used for that).

Fluka's address is Ronkomkoma, New York 11779, Phone (516) 467-0439

Merry X-mess.
