Blocking and diluting buffer and concentration : 5% NFDM/TBST.

In Western blot, ab322732 and ab106350 were shown to bind specifically to IL-8. Target of interest was observed at 11 kDa in untreated wild-type PC-3 cell lysates (lane 1) and upregulated in treated wild-type PC-3 cell lysates (lane 2). No signal was observed at this size in untreated IL-8 knockout cell line (lane 3) or treated IL-8 knockout cell line (lane 4).

Recombinant multiclonal ab322732 showed higher sensitivity than polyclonal ab106350.
