Pge2 elisa

Manufactured by R&D Systems
Sourced in United States

The PGE2 ELISA is a laboratory assay used to quantify the levels of Prostaglandin E2 (PGE2) in biological samples. It employs the enzyme-linked immunosorbent assay (ELISA) technique to detect and measure the concentration of PGE2 present in the sample.

Cytokine and Prostaglandin Profiling

Check if the same lab product or an alternative is used in the 5 most similar protocols
CM was collected from each group after centrifugation at 700 × g for 10 min at 4°C and stored at −80°C for subsequent experiments. For cytokine measurement, conditioned medium was subjected to a proteome profiler array using a mouse XL cytokine array kit (R&D, ARY028), and the relative levels of 111 cytokines and chemokines were measured. The array procedure and data analysis were performed according to the manufacturer’s instructions.
For measurement of prostaglandins, CM were collected as described and analyzed according to the manufacturer’s instructions. The ELISA kit used for measurement were as follows: PGD2-MOX ELISA(Cayman Chemical company, 500151); PGJ2 ELISA(ENZO, ADI-900-023); PGE2ELISA(R&D systems, KGE004B).

Radiation-induced PGE2 production in primary cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Primary cells were prepared as described above. On day 2 of culture, media was replaced and cells were treated with indomethacin (25 μM in saline) or vehicle (saline with 0.1% ethanol) 1 h prior to receiving a 5 Gy dose of radiation. Cell-free supernatants were collected at indicated timepoints following radiation and the PGE2 concentrations were determined with an enzyme-linked immunosorbent assay (PGE2 ELISA, R&D Systems, no. KGE004B, Minneapolis, MN) following the manufacturer’s instructions, where PGE2 was normalized to the protein concentration of the corresponding cell culture dish.

Quantifying PGE2 Levels in Cell Culture

Check if the same lab product or an alternative is used in the 5 most similar protocols
Prostaglandin E2 (PGE2) ELISA (R&D Systems, Minneapolis, MN, USA) was performed on medium collected 24 h post-impact. The collected medium was centrifuged at 12,000× g at room temperature to separate out any debris prior to performing the assay per the manufacturer’s instructions.

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.
