[Histonet] smooth muscle alpha actin antibody for mouse cells and mouse tissue?

[Jennifer A Jones]

Hi everyone - I want to stain mouse tissues and smooth muscle cells in 
culture for alpha-actin.  Apparently clone 1A4 (mouse monoclonal) is 
quite popular, but my PI wants me to find an antibody from a different 
species (rabbit, for example) to prevent excessive background staining.  
Any recommendations?  And what dilutions do you use? Thank you!! - Jen
