anti-insulin receptor antibody

[mfreis at NOMVS.LSUMC.EDU]

 Since I got such a helpful response from my previous request,
 I wonder if anyone can recommend a good source  (commercial
 or otherwise) of an anti-human insulin receptor antibody
 that does not cross react with the mouse insulin receptor???
 Companies that we have contacted so far are either prohibitively
 expensive or ambiguous about cross reactivity or both.
 Thank you,
