Cytokine and Chemokine Profiling in Lung Homogenates

We removed the whole lungs (5–8 animals per group) immediately following BAL and
prepared lung homogenate supernatants as previously described.19 (link) We converted 1 g of the homogenate suspension to 1 mL and calculated the
protein levels of various cytokines and chemokines in the total lung
homogenates. The levels of interleukin (IL)-4, IL-5, interferon gamma (IFN-γ),
IL-12 (Thermo Fisher Scientific, Inc., Chicago, IL, USA), IL-10, IL-13, IL-33,
macrophage-inflammatory protein 1-apha (MIP-1α), keratinocyte chemoattractant
(KC), monocyte chemoattractant protein-1 (MCP-1), chemokine (C-C motif) ligand
5/regulated and normal T-cell expressed and secreted (CCL5/RANTES),
CCL11/eotaxin (R&D Systems, Minneapolis, MN, USA), and monocyte-chemotactic
protein 3 (MCP-3; PeproTech, Inc., NJ, USA) in the lung homogenate supernatants
were measured using an ELISA kit, according to the manufacturer’s instructions.
Cytokine and chemokine content were expressed as pg in the total lung homogenate
supernatants.

Cytokine and Chemokine Profiling in Infected Rats

Check if the same lab product or an alternative is used in the 5 most similar protocols
Commercial ELISA kits were used to determine IL-4, IL-10, IFN-γ, TNF-α (BD Biosciences, San Jose, CA, USA) and CCL11/eotaxin (R&D Systems, Minneapolis, MN, USA) levels in intestinal tissue extracts obtained from infected and non-infected rats. Samples were run in duplicate and cytokine or chemokine concentrations were obtained by extrapolation in calibration curves. Results were expressed in pg/ml or ng/ml ± SD.
The levels of IL-5, IL-12 and IL-13 were determined by an immunoelectrotransfer blot assay as previously described [25 (link)]. Membranes were analysed by densitometry using the Image J software (NIH, Bethesda, MD, USA), and the cytokine levels were expressed as mean arbitrary units ± SD and relativized to the α-tubulin band. All reactions were performed in duplicate using ITEs obtained from two independent groups of rats (n = 5 at each dpi studied).

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.
