| Description | Cardiolipin (CL) is a complex lipid with a dimeric structure. It has four acyl chains and two phosphatidyl moieties. Its phosphatidyl moieties are linked to the glycerol backbone. Around 15-20 percent of the inner mitochondrial membrane accounts for cardiolipin.Cardiolipin is a unique phospholipid Cardiolipin (CL) is a complex lipid with a dimeric structure. It has four acyl chains and two phosphatidyl moieties. Its phosphatidyl moieties are linked to the glycerol backbone. Around 15-20 percent of the inner mitochondrial membrane accounts for cardiolipin.Cardiolipin is a unique phospholipid found exclusively within the mitochondrial inner membrane. This specific localization allows Cardiolipin to exert crucial influence on mitochondrial structure and function. Deviations in Cardiolipin content, structure, or localization can lead to impaired mitochondrial activity, contributing to various diseases like cancer, neurological disorders, cardiovascular conditions, and metabolic diseases. As Cardiolipin plays a crucial role in mitochondrial function, it holds immense potential for biomarker development and finds application in cardiovascular, neuroscience, cancer, diabetes, and metabolomics research.Application：Cardiolipin solution from bovine heart has been used:for coating Corning 96-well enzyme immunoassay/radioimmunoassay (EIA/RIA) plate to perform enzyme-linked immunosorbent assay (ELISA)-based cardiolipin binding assayin lipid analysis along with phosphatidylglycerol (PG) to comigrate the radiolabeled lipids to identify PG and cardiolipin (CL)in coating ELISA plates for antiphospholipid antibodies (aPL) assaysCharacteristics and advantages：High-quality molecule suitable for mulitple research applicationsCommonly employed in Metabolomics and Biochemical studies...

Triton X-100 solution (50 mg/ml)D. 0.01 M Phosphate buffer containing 0.1% Triton X-100 (KH2PO4-NaOH, pH 7.0)Dilute 20 ml of Triton X-100 solution (C) with approx. 800 ml of 0.01M Phosphate buffer (B). Fill up to 1,000 ml with 0.01M Phosphate buffer (B).E. NADH soluton Weigh 9 mg of NADH and dissolve in 0.1M Tris-HCl bufer (A). Fill up to 50 ml with 0.1M Tris-HCl Buffer (A). (Can be used for 5 days if kept refrigerated)F. Substrate solutionWeigh 11 mg of oxaloacetic acid and dissolve in 0.1M Tris-HCl buffer (A). Fill up to 50 ml with 0.1M Tris-HCl buffer (A) (Make a fresh solution for each use.)G. Enzyme solutionWeigh out Malate Dehydrogenase and dissolve in chilled 0.01M Phosphate Bufer containing 0.1% Triton X-100 (D). Enzyme solution should be prepared so that the value of AOD/minute becomes in the range of 0.025 ± 0.010.ProcedurePipette 2.0 ml of NADH solution (E) and 0.90 ml of Substrate solution (F) respectively into a quartz cell (d=10 mm) and keep at 25 + 0.5'℃ for 5 minutes. Then, pipete 0.10 ml of Enzyme solution (G) into the quartz cell and mix well immediately. Keep the reaction mixture at 25 ±0.5'C.Exaclly at 2 minutes and 5 minutes after the addition of Enzyme solution (G), measure the absorbances of the reaction mixture at 340 nm(A2 and A5).As a blank, pipette 0.01M Phosphate buffer (D) into another quartz cel (d=10 mm) instead of the Enzyme solution (G) and follow the same procedure described above (Ab2 and Ab5).CalculationMalate dehydrogenase activity (u/mg)=[(A2-A5)-(Ab2-Ab5)]/3*(1/6.22)*(n/0.1) ApplicationThis enzyme is used for the enzymatic determination of L-malate and gluamate oxalo-acetate transaminase(GOT)in clinical diagnosis...
