Multiplex Cytokine Quantification in BAL

Check if the same lab product or an alternative is used in the 5 most similar protocols
Measurement of cytokines in the BAL was performed taking advantage of a well-established method, Luminex® xMAP technology, that allows measuring a panel of multiple analytes on a small volume sample (100 μL) simultaneously [30 (link)]. The assay, for the quantitative detection of IL-4, IL-5, IL-10, and IL-13, was performed using a Milliplex Cytokine Panel plate (Merck Millipore) according to the manufacturer's instructions on automated immunoassay analyzer (Luminex 200™ System, Thermo Fisher Scientific) as previously described [31 (link)]. All samples were run in duplicate. After the run, data were analyzed by using Xponent software (1.9 version, Luminex 200 System; Thermo Fisher Scientific) and the final concentration of each cytokine was expressed in pg/mL.

Two femurs from each mouse were placed into a 0.5ml microtube with a hole at the bottom after their knee- caps were removed. The tube was placed inside a 1.5ml microtube, which was spun to obtained a BM cell pellet, which was suspended into 50ul PBS, and spun again. The obtained BM supernatant was stored frozen at −80°C till ready for analysis in duplicate with the Cytokine Mouse 20-Plex Panel for Luminex® Platform (LMC0006, Thermo Fisher Scientific) according to manufacturer’s instructions. Data were acquired on a Luminex200 system equipped with xPONENT 3.1 software (Thermo Fisher Scientific). Human BM plasma obtained from MM patients enrolled in the clinical trial at baseline and three or four weeks after LCL161 single agent treatment was assayed in duplicate using the Cytokine Human 30-Plex Panel for Luminex® Platform (LHC0003, Thermo Fisher Scientific). Similar analysis was performed on peripheral blood plasma from MM patients collected at baseline and four hours after LCL161 administration.

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.
