IL-1β in microglia culture supernatant was measured with Mouse IL-1β /IL-1F2 DuoSet ELISA Kit (R&D Systems DY401, Minneapolis MN) according to the manufacturer's instructions. CXCL10 was measured in neuronal culture supernatant with Mouse CXCL10 DuoSet ELISA (R&D Systems DY466-05, Minneapolis MN) according to the manufacturer's instructions. Primary microglia were stimulated with recombinant Mouse CXCL10 protein (R&D Systems 466-CR-608 050/CF, Minneapolis MN) and incubated with Mouse CXCL10 antibody (R&D Systems AF-466-609 NA, Minneapolis MN). TNF-α and IL-1β were measured in the supernatant by ELISA with Mouse TNF-α Quantikine ELISA Kit (R&D Systems MTA00B, Minneapolis MN) and Mouse IL-1β/IL-1F2 DuoSet ELISA Kit according to manufacturer's instructions.

Quantification of Inflammatory Cytokines in Allergen-Challenged Skin

Check if the same lab product or an alternative is used in the 5 most similar protocols
IL-1β, IL-6 and TNFα were quantified from full ear skin samples (dermis + epidermis) following allergen re-exposure. The skin was removed from the cartilage tissue using surgical tweezers, and snap-frozen in liquid nitrogen 24 h post challenge. Samples were submerged in 800 µL lysis buffer (50 mM Trizma base, 250 mM NaCl, 6.4 mM EDTA, 17.6 mM Triton X-100, pH 7.4, including protease inhibitor cocktail (cOmplete, Roche Diagnostics GmbH, Berlin, Germany)). Tissue homogenization was performed in MK28 hard grinding precellys tubes (Bertin Technologies, Montigny-le-bretonneux, France) using a Precellys Evolution instrument (Bertin Technologies). Protein concentration in the supernatant was quantified by a Bradford assay and stored at −80 °C. The protein concentration of all samples was adjusted to 2 mg/mL. IL-1β levels were analyzed using a mouse IL-1β/IL-1F2 DuoSet ELISA kit (R&D systems), on 10× diluted samples. IL-6 and TNFα levels were analyzed using respective ELISA MAX™ standard kits (Biolegend) on undiluted samples. All assays were performed following manufacturer’s protocol.

Quantifying Cytokine and Cytotoxicity Levels

Check if the same lab product or an alternative is used in the 5 most similar protocols
Cytokine levels in cell supernatants were assessed using the mouse IL-1β/IL-1F2 DuoSet ELISA kit (R&D Systems) and mouse TNF-α DuoSet ELISA kit (R&D Systems) according to the manufacturer’s instructions. ELISA plates were measured at OD450 using a microplate reader, and cytokine levels were quantified by interpolation using a standard curve. Supernatants were assayed for LDH release immediately after stimulation time courses per the manufacturer’s protocol from the CytoTox 96 Non-Radioactive Cytotoxicity Assay (Promega). Measurements of absorbance readings were performed on a microplate reader at wavelengths of 490 nm and 680 nm. LDH release was assessed as a percentage of background-subtracted maximum LDH values from lysed cells.

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.
