small protein - (Jul/24/2006 )

Hi, I am looking for some very small proteins(MW<10dD) for binding assay. I don't know where I can get these kind of proteins. If somebody knows small proteins, please let me know.

Thanks a lot.

Can you use insulin, ubiquitin or soybean typsin inhibitor? You can get them from Sigma.
