Lysophosphatidylcholine 18:2
Based on 1 Customer Validation
Lysophosphatidylcholine 18:2 (1-Linoleoyl-2-Hydroxy-sn-glycero-3-PC), a lysophospholipid, is a potential biomarker identified from insulin resistance (IR) polycystic ovary syndrome (PCOS). Low plasma Lysophosphatidylcholine 18:2 also has been shown to predict impaired glucose tolerance, insulin resistance, type 2 diabetes, coronary artery disease, and memory impairment.

Lysophosphatidylcholine 18:2 (1-Linoleoyl-2-Hydroxy-sn-glycero-3-PC) contributes to the separation of IR PCOS and control groups. Significant decrease in the levels of phosphocholines (PCs) and lyso PC (18:2), and increase in trilauric glyceride level are observed in the plasma of IR PCOS[1].
Lysophosphatidylcholine (LPC), a major class of glycerophospholipids in human plasma, are implicated in inflammation, insulin resistance, obesity, and type 2 diabetes[2].

Solvent & Solubility
Ethanol : ≥ 100 mg/mL (192.44 mM)
DMSO : 40 mg/mL (76.97 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
* "≥" means soluble, but saturation unknown.
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (stored under nitrogen). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% EtOH 40% PEG300 5% Tween-80 45% Saline
Solubility: 3.03 mg/mL (5.83 mM); Clear solution; Need ultrasonic
This protocol yields a clear solution of 3.03 mg/mL.
Taking 1 mL working solution as an example, add 100 μL EtOH stock solution (30.3 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: 2.5 mg/mL (4.81 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: 2.5 mg/mL (4.81 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
