Description of Dihomo-γ-Linolenic Acid-d6

Dihomo-γ-Linolenic Acid-d6 (DGLA-d6) contains six deuterium atoms at the 8, 9, 11, 12, 14, and 15 positions. It is intended for use as an internal standard for the quantification of DGLA by GC- or LC-mass spectrometry. Dihomo-γ-Linolenic Acid (DGLA, 20:3), an elongation product of γ-linolenic acid (18:3), is rapidly metabolized by fatty acid desaturases to produce arachidonic acid (20:4). DGLA is metabolized through the cyclooxygenase pathway to produce 1-series prostaglandins, (PGs), including PGE1.1,2 In mice, DGLA supplementation in the diet can reduce atopic dermatitis and atherosclerosis.3,4

Calculation results:

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL saline, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
3. All of the above co-solvents are available for purchase on the GlpBio website.
