Help! Immunoprecipitation beads that mouse IgM can bind

 I want to try immunoprecipitation by a mouse monoclonal antibody. 
But it is IgM, not IgG. Does anybody know anti-mouse IgM-binding beads,
 or beads that mouse IgM can bind? From where can I get? Protein A beads
 bind to human IgM, but can't to mouse IgM. Any comment?

Thanks in advance.
