human nestin antibody for immunohistochemistry

[news at aida.med.teikyo-u.ac.jp]

Greetings,
I'm currently setting up a project that will involve the usage 
of the anti-human nestin antibody for immunohistochemistry but 
so far I haven't been able to locate a supplier.  

Could anyone help me with this?  I'd appreciate it very much.
Best, Yasuo
