Octanoylcarnitine

Description

Octanoylcarnitine is a medium-chain fatty acid (octanoic acid: eight-carbon saturated fatty acid) covalently linked to carnitine, frequently applied as a substrate for fatty acid oxidation (FAO) in mitochondrial preparations.

Abbreviation: Oct

Application in HRR

Oct: Octanoylcarnitine (DL-Octanoyl-carnitine-HCL, C₁₅H₃₀NO₄Cl); TOCRIS Bioscience, Cat. No. 0605, 50 mg, store at RT, desiccate); FW = 323.85.

Alternative: (±)-Octanoylcarnitine chloride, BioTrend, Cat. No. BS0136, 50 mg, store desiccate at RT; FW = 323.86.

Preparation of 100 mM stock solution (dissolved in H₂O or DMSO, can differ from batch to batch - check Certificate of Analysis):

Weigh 50 mg of octanoylcarnitine and dissolve in 1543 µL H₂O or DMSO.
Divide into 0.2 mL portions.
Store at -20 °C.

O2k manual titrations into 2 mL O2k-chamber

Titration volume: 10 µL using a 25 µL syringe.
Final concentration: 0.5 mM in MiR05 or MiR06. Optimum Oct concentrations have to be evaluated, particularly in media with BSA concentrations different from MiR05.
