I immunoprecipitate my protein of interest using Protein A.G Sepharose 
beads. Since I want to further analyse the protein of interest using 1D 
IEF I am looking for the best method to release the protein of interest 
from the IP-antibody protein A/G sepharose complex for subsequent 
analysis. SDS can not be used because of the negative charge interfering 
with IEF. Appreciate advice!
