I,m an M. Sc. student in marine biology, My thesis is about oxidative stress in euryglossa orientalis ( a flatfish). I used this paper : response of antioxidant enzymes in catfish exposed to liquid crystal from E-west ( An et al, 2008) for SOD assay. there is a formula : 1U= (K0- KSOD )/(3lxK0/2) whithout any describtion about it, i dont know how i can calculate K0, KSOD, and i dont know what lx is. I cant find its refrence paper. I will gratfull if anybody knows about it contact me.
