You might want to look at this paper (JBC (2007) 282, 34219) by Nagai et al.  They say that..." Purified rabbit polyclonal antibody against 2SC was prepared by Eurogentec (San Diego, CA)."

Thank you so much for the response David. I've already had a look at the "Nagai et al paper. I emailed Eurogentec this morning to see if they could prepare the polyclonal 2SC Ab. for us and their reply was, "it'll take roughly 3 months to get it done", which I think is a little bit over the limit as I need it quite urgently. The other option of course is to message the authors of the paper directly if they've got any spares. I guess i'll do that right away.  Thanks though :)
