I have used the B9 bioassay for equine serum, and for supernatants. I
would like to have a reliable and reasonably priced ELISA to run a large
number of samples for equine IL-6 and TNFalpha in equine serum, CSF,
synovial fluid, peritoneal fluid, urine, maternal fluids (ie amniotic) and
colostrum/milk.
