Donkey Anti-Mouse IgG (H+L) Secondary Antibody, Alexa Fluor® 647 Conjugate

This is a great product to do immunofluorescence. We study primary cells (airway epithelial cells) in our lab and can use several different donkey alexas with different fluorophore conjugations in a single staining without any issue. A dilution of 1:2000 for 30 to 60 minutes works great with most of them. The only issue is that usually when the product is running low or is old, like most conjugated antibodies, they tend to aggregate .
