The cost to perform one measurement was €5 per patient [ 28]. (2) Plasma and BAL fluid sTREM-1 levels were measured using a commercially available sandwich ELISA kit (Sigma-Aldrich, St Louis, MO, USA) following the manufacturer instructions (detection limit 8 pg/ml).
DIG Wash and Block Buffer Set (Roche) was used for washing and blocking incubations according to manufacturer's instructions, and detection was made with CDP- Star (Roche) also following the instructions.
After 2 h of incubation with horseradish peroxide-conjugated secondary antibody, immunoreactive proteins were detected by enhanced chemiluminescence per the manufacturer's instructions (ECL detection system; Amersham Biosciences).
Results suggest that revealing details to participants through instructions biases detection rates in the P300-CIT toward enhanced sensitivity.
According to the manufacturer's instructions, the detection limit for feed samples was 1.75 μg/kg with the recovery rate of 85%%.
According to the manufacturer's instructions, the detection limit for milk samples was 5 μg/L with a recovery rate of 95%%.
One question that naturally follows from these results relates to the fact that on-line and off-line processing was tested with two different task instructions (probe detection vs. emotional prosody categorization).
Levels of IL-17, IFN-γ, IL-6, TGF-β, IL-23, IL-10 and IFN-β were measured using commercially available ELISA kits according to the manufacturer's instructions with detection limits of 15.6 pg/ml, 31.3 pg/ml, 15.6 pg/ml, 15.6 pg/ml, 31.3 pg/ml, 31.3 pg/ml and 15.6 pg/ml respectively.
Incubation and washing steps were performed according to manufacturer's instructions; peroxidase detection was determined spectrophotometrically with ABTS as substrate.
The TUNEL assay was performed according to the manufacturer's instructions (Apoptosis Detection System, Fluorescein; Promega Corporation, Madison, WI) (29).
