protein mass weight different?

Hi, everyone

          By immunoscreening methods,our lab has gotten a new gene. However
surprisingly, the protein mass weight that I expressed the gene in E.coli is
much smaller than that obtained by immunoprecipitation.
    The first possibility we come into mind is that glycosylation.
      But we can not find any glycosylation site in our predicted protein
       Could you give me some suggestions?
Many thanks!
