Measuring the LPS induced response in IC-21 cells:

A 12-plex mouse inflammatory cytokine multi-analyte ELISArray kit (Qiagen) paired with LPS O111:B4 (phenol extract, Sigma Aldrich) was used to determine how many hours of LPS exposure was required to produce a measurable cytokine response. Limit of detection for the ELISAarray 12-plex kit is stated by the manufacturer as 10 pg/mL for each given cytokine. For further in-depth examination we chose ULTRA PURE LPS O111:B4 (List Labs) to avoid contaminates often found in other LPS preparations. …

Results:

… For each ligand, inhibition of cAMP accumulation was blocked by pretreatment with PTX (100 ng/mL), indicating that these were Gi-mediated effects (octreotide not shown) (Fig. 1C and 1D). These results demonstrate that in pituitary tumor cells, both octreotide and SOM230 had full efficacy for cAMP inhibition and this effect was fully inhibited by PTX. …
