Polycarbonate membrane, Nucleopore address?

[Shumin Duan]

A colleague of mine engaging in the research of brain implantation need   
some polycarbonat membrane with 12 um pores but can not get it in China.   
    It would be greatly appreciated if you could tell us the address of 
the
        company selling the membrane (Nucleopore probably) or kindly 
send
some  to her as gift(Dr.Hui-Juin Xiu, Dept. of Anatomy, Nantong Medical    
  College, Nantong 226001, Jiangsu, P.R.China. E-mail:   
duan at physiol.med.kyushu-u.ac.jp). Thank you.
