m-PEG550-OH
Based on 1 Customer Validation
m-PEG550-OH (mPEG550-Hydroxy) is a monomethoxypolyethylene glycol and also a macroinitiator for organocatalytic ring-opening polymerization of aliphatic cyclic carbonate monomers. m-PEG550-OH can participate in the synthesis of amphiphilic block copolymers. Amphiphilic block copolymers can be used to prepare nanoscale micelles for active drug delivery.

Beschreibung
In Vitro
m-PEG-OH can be used to encapsulate anticancer drugs. Hydrophobic anticancer agent Paclitaxel (HY-B0015) encapsulated in micelles exhibits stronger cancer cell-killing activity than free Paclitaxel. In addition, it preferentially accumulates in tumor tissues and shows only limited distribution in healthy organs[2].

Lösungsmittel & Löslichkeit
In Vitro:
DMSO : 200 mg/mL (Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Konzentration (Stammlösung) × Volumen (Stammlösung) = Konzentration (Ziellösung) × Volumen (Ziellösung)
In Vivo:
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% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 5 mg/mL; Clear solution
This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL. * In solvent : -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture)
1. Take μL DMSO stock solution;
2. Add μL .

3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
