RE: [Histonet] Laminin antibody

From:"Dawson, Glen"

I use this antibody @ a 1:25 dilution.  Dako LSAB2 detection.  Dako
Proteinase K enzyme retrieval for 5 minutes & it works very well.

Subject: [Histonet] Laminin antibody

Dear Histonetters,
Are there any people who have experience with the following anti-laminin
antibody: mouse monoclonal, clone 4C7 from DAKO (code no: M0638)?
We tried to use this antibody on paraffin-embedded human skin tissue
(formalin-fixed), but it did not work. We tried several antigen
retrieval procedures, like pepsin, proteinase K and trypsin digestion,
but all of these fail.
Does anyone know an appropriate antigen retrieval or should I try
another antibody? 
Thank you for your help.
