We use serum for IHC from Equitech Bio. They have a minimum order of
$50 but their serum is about $40 for 500 ml--cheap and reliable.
"Prosperity ripened the principle of decay...and, as soon as time or
accident and removed the artificial supports, the stupendous fabric
yielded to the pressure of its own weight...instead of inquiring why
the Roman Empire was destroyed we should rather be surprised that it
has subsisted for so long"
-Edward Gibbon, Decline and Fall of the Roman Empire
