retrovirus and polybrene

I am setting up a transformation assay using murine retroviruses as
carriers of the gene of interest. And being a rookie with this system I
have some very simple questions...
What would be a good source of polybrene which is used to enhance the
infectivity of the particles. I think the substance is called
hexadimethrine bromide. Is the pure stuff from sigma catalog OK for this
purpose? Anyone who has experience with Retronectin? I would be more than
happy to get some tips to think about using this infection method
(protocols other than Curr. Prot. Mol. Biol. or Maniatis).

Thanks in advance!
