[Histonet] Anti-human abs work on porcine tissue

[Adam .]

I routine use anti-human antibodies to stain mouse tissue, so it can be
done. It completely depends on the antigen they used to immunize. If the
human and pig proteins are highly homologous or identical, then it has a
good chance of working. If they're not, you're in uncharted territories. If
you ask nicely, most companies will tell you what antigen or antigen
fragment they used, but most don't actively advertise this.
