Hello,

Can anyone recommend good positive controls for MMP-13 and Procollagen I in 
mouse skin?  I have been playing around with these antibodies on frozen 
sections and have got some positive staining, however, I really need to 
test them on positive controls as my staining patterns, particularly for 
Procollagen I, don't agree with the recent literature.  Thank you again!!
