Il 25

Manufactured by Merck Group
Sourced in United States, Australia

IL-25 is a laboratory equipment product from Merck Group. It is used to measure and quantify the levels of interleukin-25 (IL-25), a cytokine involved in immune system regulation and inflammatory responses. The core function of IL-25 is to facilitate the detection and analysis of this specific protein in biological samples.

CFs were cultured as described previously [32 (link)–35 ]. CFs were then divided into four groups according to cell treatment, namely: (1) control group, (1%FBS-DMEM); (2) TGF-β1 treatment group (1%FBS-DMEM + TGF-β1[10 ng/ml, R&D Systems]); (3) IL-25 treatment group(1%FBS-DMEM + IL-25 [10 ng/ml, R&D Systems]); and (4) IL-25 + PI3K-antagonist group (1%FBS-DMEM + IL-25 [10 ng/ml] + LY294002 [15 μM, Sigma-Aldrich)]). Cells were then cultured for another 24 h and then harvested for further analyses, including real-time PCR, western blotting, ELISA, and cell proliferation and migration analyses.

16HBE cells were seeded in 6 well plates and treated with treated with IL-25 (100 ng/ml), thapsigargin (Tg, 0.5uM) and 4-PBA (5 mM; Sigma, St Louis, USA) respectively in a serum-free culture medium. After treatment 2 hours with 4-PBA, the medium containing IL-25 (100 ng/ml) was added to co-incubate cells. Following treatment, the cells were harvested by 0.2% trypsin. 106 cells were suspended in 100ul binding buffer with 5ul Annexin V-FITC and 5ul PI staining solution for 10 min at room temperature. The samples were set to analysed by a FACS array. Data were analyzed by software flowjo (FlowJo flow cytometry analysis software, Tree Star, USA).

Quantifying Esophageal Gene Expression

Mouse oesophagi were immersed in RNAlater ® (Ambion, Life Technologies Australia, Mulgrave, Australia) before being frozen at −80°C. Total RNA was then isolated using TRIzol® RNA extraction (Invitrogen, Life Technologies Australia, Mulgrave, Australia) and reverse transcribed to cDNA using BioScript (Bioline, Alexandria, Australia).
Gene expression within the oesophagus was determined using RT-qPCR (Eppendorf Realplex, Hamburg, Germany) and SYBR Green (Invitrogen, Life Technologies Australia, Mulgrave, Australia). Primers specific for murine MID1 (Forward: 5-CACTCGCTGAAGGAAAATGACCA-3, Reverse: 5-AATCCAAGGCAAAAGTGTCAAA CG-3), CCL11 (F: 5-TTCTATTCCTGCTGCTCACGG-3, R: 5-AGGGTGCATCTGTTGT TGGTG-3), TGF-β (F: 5-TGTGGAACTCTACCAGAAATATAGC-3, R: 5-GAAAGCCCT GTATTCCGTCTC-3), TSLP (F:5-AGGCTACCCTGAAACTGAG-3, R:5-GGAGATTGCA TGAAGGAATACC-3) CCL20 (F:5-CGACTGTTGCCTCTCGTACA-3, R: 5-AGGAGGTTCACAGCCCTTTT-3) IL-25 (F: 5-ATGTACCAGGCTGTTGCATTCTTG-3) (R: 5-CTAAGCCATGACCCGGGGCC-3) (Sigma-Aldrich, Castle Hill, Australia) and CCL24 (Biomol, VMPS-907, Enzo Life Sciences, Farmingdale, NY) were used to quantify mRNA copy numbers as described previously [38 (link)]. Murine β-actin was used as a housekeeper gene and gene expression was determined as mRNA copies of the gene of interest per copy of β-actin (F:5-GACGGCCAGGTCATCACTATTG-3, R:5-AGGAA GGCTGGAAAAGAGCC-3).

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.
