Table 2. Chemically modified [Cit5]CXCL8 recovery from cell culture supernatants.

Complex sample [Cit5]CXCL8 recovery (%) ± SEM
PBMCs 84.0±10.8
Granulocytes 87.1±11.5

Culture supernatants of unstimulated cells were spiked with 20 ng/ml [Cit5]CXCL8 before chemical modification and detection. Results represent the mean % (± SEM) for n = 11.
