Serum Cytokine Detection Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
For serum cytokine detection, blood samples were collected together with CRP and PCT samples at time points 0, 12, 24, 48, 72, and 96 h after study inclusion. The serum samples were kept at −75 °C until they were analyzed at the Virus Diagnostics Laboratory, University of Turku. Serum cytokine levels were determined by 27-plex immunoassay (IL-1β, IL-1rα, IL-2, IL-4, IL-5, IL-6, IL-7, IL-8, IL-9, IL-10, IL-12 (p70), IL-13, IL-15, IL-17, eotaxin, FGF basic, G-CSF, GM-CSF, IFN-γ, IP-10, MCP-1, MIP-1α, platelet-derived growth factor (PDGF-ββ), MIP-1, RANTES, TNF-α, vascular endothelial growth factor (VEGF)) from Bio-Rad Laboratories, Inc. (California, United States)). According to the manufacturer’s instructions, except that the amount of beads, detection antibodies, and streptavidin-phycoerythrin conjugate were used at 50% of their recommended concentration, which was tested previously as appropriate for the analysis system. The results were analyzed with Bio-Plex Manager 6.0 software. For statistical analyses and calculating the geometric mean cytokine levels, samples under the detection limit were given a value that was the detection limit divided by two. This was done in order to enable the inclusion of negative values (0 values) for geometric mean calculations.

LPS isolated from Escherichia coli (0111:B4) was purchased from Sigma–Aldrich (St. Louis, MO, USA). Multiplex beads for: IL-1β, IL-2, IL-4, IL-6, IL-8, IL-10, IL-12 (p70), IL-17, G-CSF, GM-CSF, IFN-γ, MCP-1, MIP-1α/1β, RANTES, TNF-α, VEGF, IP-10, and GRO-α were purchased from Bio-Rad Laboratories (Hercules, CA, USA). TGFβ was purchased from Peprotech (Rocky Hill, NJ, USA) and neutralizing TGFβ Ab was purchased from R&D (Minneapolis, MN, USA). For flow cytometry PE-conjugated anti human-CD14 and FITC-conjugated anti human-CD16 Abs purchased from eBioscience (San Diego, CA, USA) were used at a 1:50 dilution.

Cytokine Profile of IL-17 and TNF-α Treated HDMECs

Check if the same lab product or an alternative is used in the 5 most similar protocols
HDMECs were starved in EBM supplemented with 2% fetal bovine serum for 6 hours and then untreated or treated with 10 ng/ml IL-17 or TNF-α or both in EBM plus 2% fetal bovine serum for 24 hours. Conditioned medium was collected and analyzed by means of xMAP technology using a X200 Luminex platform (Bio-Plex) equipped with a magnetic workstation. Panel used was the PRO Human Cytokine 27-PLEX for the simultaneous detection of FGF basic, Eotaxin, G-CSF, GM-CSF, IFN-γ, IL-1β, IL-1ra, IL-2, IL-4, IL-5, IL-6, IL-7, IL-8, IL-9, IL-10, IL-12 (p70), IL-13, IL-15, IL-17A, IP-10, MCP-1 (MCAF), MIP-1α, MIP-1β, PDGF-BB, RANTES, TNF-α, and VEGF-A (BioRad) according to the manufacturer's instruction. Data were analyzed using Bio-Plex Software Manager 6.1. Duplicate wells were used for each condition. Coefficient of variation (CV) of measurements of the whole panel was always lower than 10%.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
