Anti-FOXN1 antibody images

  • Immunohistochemical analysis of formaldehyde-fixed paraffin-embedded human skin tissue sections, labelling FOXN1 with ab26069 at a dilution of 1/25 incubated for 18 hours at 4°C. Permeablization was with 0.05% Tween. Blocking was with 5% serum incubated for 20 minutes at room temperature. The secondary used was a swine polyclonal biotin-conjugate at 1/1000.
