Currently, I am trying to stain muscle frozen section with three antibodies CD31, PAX7 and laminin.
I have tried fixing them using ice-cold 100% methanol and 4% formaldehyde. block for 45 min and incubate for primary and secondary for 1h.
Blocking buffer: M.O.M kit vector labs
the laminin works greats but for the PAX7 the image has many background staining.
any suggestions will be appreciated.
thanks
