Cytokines in the cell-free culture supernatant were quantified using BD CBA Human Inflammation kit and Human Th1/Th2 kits (BD Biosciences, France).
Human CD4+CD25+ Tregs isolation kit and human fluorescein isothiocyanate (FITC -conjugated anti-human CD4 (IgG1, Clone M-T466) were purchased FITC -conjugatedotec GmbH (Bergisch Gladbach, Germany).
Nitrocellulose membranes to which capture antibodies have been spotted and reagents for detection were obtained as 'Human apoptosis array kit' and 'Human pluripotent stem cell antibody array kit' from R&D Systems (Wiesbaden-Nordenstadt).
Human IL-1 beta/IL-1 F2 Quantikine ELISA Kit and Human CXCL10/IP-10 CXCL10/IP-10LISA Kit (R& D Systems™) were used to QuantikinehELISAlytes for further comparison with the Proteome Profiler™ outcome.
Level of plasma cytokines was measured using Human Tumor necrosis factor α ELISA Kit and Human Interleukin 6 ELISA Kit (EIAab, Wuhan, China), according to the standard protocols of the manufacturer.
Matrix metalloproteinases-2 (MMP-2) and -9 (MMP-9) in cellular homogenates from CHO-AFs, MEAC-Fs, NAS-Fs and perilesional-Fs were quantified using the human MMP-2 ELISA kit and human MMP-9 ELISA kit (Quantikine®; R&D Systems, Minneapolis, MN) according to the manufacturer's protocol.
There are all sorts of Ripper-related material and framed Sickerts and decades' worth of original Times newspapers in bound volumes, as well as modern forensic kits and a human skeleton.
After purification with Amicon Ultra Centrifugal Filters (MILLIPORE GmbH, Vienna, Austria) the two labeled products together with blocking agent, Hybridization Buffer (both included in the Oligo aCGH/Chip-on-Chip Hybridization Kit, Agilent Technologies), and human cot-DNA (Roche Austria GmbH, Vienna, Austria) were combined and hybridized onto 4 × 44 K oligonucleotide arrays.
Serum samples obtained from patients were analyzed for cytokine and chemokine levels using a BD cytometric bead array (CBA) human chemokine kit and a human inflammatory cytokine kit (BD Biosciences, San Jose, CA) according to the manufacturers' instructions.
To confirm that murine IL-6 is not detected by the human IL-6 ELISA, recombinant murine IL-6 at 1,000, 500, 100, and 65 pg/mL concentrations were assayed with the human ELISA kit and no human IL-6 was detected.
