[Histonet] Anti human - alpha 3,4,5 or 6 type iv collagen

[ole]

Hi
Im looking for anti-human antibodies against; Alpha (3, 4, 5 or 6) type IV Collagen. 
(Alport syndrome)
Do anyone have recommandations of some of these antibodies? 

I would prefer that they works on formalinfixed tissue, but we have also fresh-frozen and alcohol fixed tissue from this kidney.

Best regards
