Is there radioactive SDS available?

[carlos h. pedemonte]

        I am trying of measuring the amount of SDS that binds to a protein
during solubilization. I suppose the best way to do it will be to determine
the amount of bound radioactive SDS. I couldn't find radioactive SDS. Does
anybody knows about a company or somebody who may have radioactive SDS? I
would appreciate suggestions about alternative methods. Thanks.
