Human cytokine array kit

Manufactured by R&D Systems
Sourced in United States, Germany, United Kingdom

The Human Cytokine Array Kit is a multiplex assay for the simultaneous detection and quantification of multiple human cytokines, chemokines, and growth factors in a single sample. The kit utilizes capture antibodies spotted on a membrane to bind and detect target analytes. This allows for the parallel measurement of a variety of targets in a simple, rapid, and sensitive manner.

The cytokine array analysis was performed according to the method of a previous study [30 (link)], with some modifications. Cells were untreated (control) or treated with chrysophanol, and the medium was replaced with serum- and antibiotic-free DMEM for the final 24 h of the incubation. Medium from three wells was pooled, clarified by centrifugation at 200× g at 4 °C, and immediately applied to the Human Cytokine Array Kit according to the manufacturer’s instructions (R&D Systems, Minneapolis, MN, USA). The cytokine array signal was detected at multiple exposure times, ranging from 15 s to 10 min. The film was scanned using a ChemiDocTMXRS + System (Bio-Rad Laboratories, Hercules, CA, USA). Signal levels were measured using ImageJ software, with the Protein Array Analyzer plugin 16.
The Human Cytokine Array Kit was provided by R&D Systems and was used according to manufacturer’s introduction and the method suggested by a previous study [31 (link)]. The image of spots was scanned and measured using NIH ImageJ software with the Protein Array Analyzer plugin 16.

Synovial fluid mediators were determined by screening pro-inflammatory cytokines on three SF using a membrane-based Human Cytokine Array kit (ARY005B, R&D Systems, Minneapolis, MN, USA). The chemiluminescent signals were visualized with a ChemiDoc XRS+ imaging system (Bio-Rad, Hercules, CA, USA) and analyzed using Image Lab 5.0. IL-6 and IFN-γ levels were quantified by ELISA according to the manufacturer's instructions (R&D Systems). Concentrations of MCP-1 levels were determined by Cytometric Bead Array (BD Biosciences, San Diego, CA, USA). Data was acquired on an LSRII cytometer (BD Biosciences) and analyzed using FCAP array v3 software (BD Biosciences). Quantification of IL-1β, IL-23, IL-12p70, IL-12p40, CCL17, CXCL10, IL-10, and IL-1RA in SF was performed by the LegendPlex Human M1/M2 Macrophage Panel (BioLegend, San Diego, CA, USA). Data was acquired on a MACSQUANT Q10 cytometer (Miltenyi Biotec, Bergisch Gladbach, Germany) and analyzed using Legendplex Data Analysis Software (BioLegend).
IL-6 and TIMP3 were quantified in ADSC culture supernatants by ELISA (R&D Systems).

To profile the response of stimulated HT-29 epithelial cells, 38 cytokines were simultaneously analyzed using a Human cytokine array kit (Cat no. ARY005, R&D Systems, Abingdon, UK) according to the manufacturer’s instructions. Qualitative analysis was performed by comparing the density of the detected spots to that of the reference spots included in the assay.

Cytokines, chemokines, and acute phase proteins were detected with the Human Cytokine Array Kit (R&D Systems) according to the manufacturer’s instructions. Pooled sera collected from control non-pregnant individuals and pregnant donors during the first, second, and third trimesters of gestation were centrifuged and incubated with the pre-coated nitrocellulose membranes. After washing and addition of the detection antibody streptavidin–HRP conjugates, the membranes were exposed to X-ray film (Fuji). The cytokine proteomic array comprised 36 targets spotted in duplicate on the membranes. The intensity of each spot in the captured images was analyzed with ImageJ analysis software (NIH Image Processing).

Analysis of phosphorylation profiles of kinases and their protein substrates, as well as analysis of expression of apoptosis-related proteins was done by the Human Phospho-Kinase Array (R&D Systems, Minneapolis, MN) and Human Apoptosis Array Kit (R&D Systems). For both, untreated and overnight 1 μg/ml cisplatin pretreated MSC were solubilized at 1 × 107 cells/ml in lysis buffer at 2–8 °C for 30 min and proceeded according to manufacturer’s protocol. ImageJ software (NIH, Bethesda, MD) was used for the quantitative evaluation; pixel density was determined and calculated.
Cell supernatant of untreated MSC and pretreated MSC as above was analyzed by Human Cytokine Array Kit (R&D Systems) used to simultaneously detect the relative levels of 36 different cytokines, chemokines, and acute phase proteins according manufacturers protocol.

Cytokine and Adipokine Profiling of BxPC-3 Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
The relative amounts of cytokines in BxPC-3 fresh growth medium and supernatants were evaluated by a Human Cytokine Array Kit (ARY005B, R&D Systems) by following the manufacturer’s protocol. Briefly, 1 mL of fresh BxPC-3 growth medium or BxPC-3 supernatants was mixed with a cocktail of biotinylated detection antibodies and incubated with the array membrane overnight at 4 °C. After washing three times with washing buffer (10 min each time), streptavidin-horseradish peroxidase solution and chemiluminescent detection reagents were added to the membrane in sequence. Then, the array membranes were imaged and scanned. The pixel density of each dot was analyzed with ImageJ software.
Adipokines released from the eWAT after being induced with CM and control GM were also evaluated. The relative amount of adipokines was calculated as the ratio of the adipokine pixel density/positive control pixel density from the CM induced samples to the adipokine pixel density/positive control pixel density from the GM.

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.
