Direct 8 iso pgf2α elisa kit

Manufactured by Enzo Life Sciences
Sourced in United States, Switzerland

The Direct 8-iso-PGF2α ELISA kit is a laboratory tool used for the quantitative measurement of 8-iso-PGF2α, a biomarker of oxidative stress, in biological samples. The kit utilizes an enzyme-linked immunosorbent assay (ELISA) technique to detect and quantify the target analyte in the sample.

Measurement of 8-iso-PGF2α in Serum

Check if the same lab product or an alternative is used in the 5 most similar protocols
To prepare the serum concentration of F2‐isoprostane, 8-Iso-Prostaglandin F2α (8-iso-PGF2α) was measured with a direct 8-iso-PGF2α ELISA kit (Enzo Life Sciences, Inc. Farmingdale, NY 11735) according to the manufacturer’s instructions. The absorbance was read at 405 nm with a UV spectrophotometer (Molecular Devices).

Liver Lipid Peroxidation Assay

Check if the same lab product or an alternative is used in the 5 most similar protocols
Livers were excised, weighed, and immediately frozen at −80 °C. The frozen tissues from each rat were homogenized in ice‐cold phosphate buffer (KCl 140 mM, phosphate 20 mM, pH 7.4) and centrifuged at 3000 rpm for 10 min. Protein concentration in the liver homogenates was determined using bovine albumin solution.21 LPO was determined by estimating the level of F2‐isoprostanes, a promising oxidative stress marker, which was detected in the liver using the commercially available Direct 8‐iso‐PGF2α ELISA kit (Enzo Life Sciences, Farmingdale, USA). A true reflection of both free and esterified isoprostane was measured following the manufacturer's instructions.

In plasma, assay kits were used to determine glycemia (Randox Laboratories, Crumlin, Antrim, UK), free fatty acids (NEFA kit, Roche, Mannheim, Germany), leptin (Rat leptin ELISA kit, Crystal Chem, Netherlands), LDL and HDL cholesterol (Abcam, ab65390) and 8-iso-PGF2α (Direct 8-iso-PGF2α ELISA kit, Enzo Life Science, Lausen, Switzerland).
In hearts, malondialdehyde (MDA) and mitochondrial citrate synthase (CS) activity were evaluated (MAK085-1KT, Sigma-Aldrich; CS0720, Sigma-Aldrich; Saint-Louis, MO, USA) after ischemia-reperfusion injury.

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.
