Based on 1 publication(s) in Google Scholar
PLGA-PEG-MAL (20KDA-5.0KDA, LA:GA RATIO 40:60) is a biodegradable amphipathic polymeric nanocarrier of poly (lactic-co-glycolic acid)-block-poly (ethylene glycol) (PLGA-PEG-Mal) that allows covalent modification of functional molecules. PLGA-PEG-MAL (20KDA-5.0KDA, LA:GA RATIO 40:60) modified with Angiopep-2 can cross the blood-brain barrier and exhibits targeting selectivity for glioblastoma cells. PLGA-PEG-MAL (20KDA-5.0KDA, LA:GA RATIO 40:60) can capture tumor-derived protein antigens, and exerts immunomodulatory effects when conjugated with anti-OX40 antibody; when used in combination with A2-CL/Dbait nanoparticles and radiotherapy, it prolongs survival time and reduces tumor volume in glioblastoma mouse models. PLGA-PEG-MAL (20KDA-5.0KDA, LA:GA RATIO 40:60) can be used for studies related to bacterial wound infections and glioblastoma.

Biological Activity
Description
In Vitro
PLGA-PEG-MAL (20KDA-5.0KDA, LA:GA RATIO 40:60) covalent grafting of MSI-78 (4-20) at a concentration of 326 μg/mL yields a positively charged stable nanosystem. This product exhibits MIC values of 16-32 μg/mL and 8-16 μg/mL against Staphylococcus aureus ATCC 25923 and Pseudomonas aeruginosa ATCC 27853, respectively. In simulated wound fluid, only its anti-P. aeruginosa activity slightly decreases, while its bactericidal rate is significantly enhanced, and no cytotoxicity to HFF-1 cells is observed at the MIC dose[2].

Solvent & Solubility
In Vitro:
DMSO : ≥ 100 mg/mL
* "≥" means soluble, but saturation unknown.
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 40% PEG300 5% Tween-80 45% Saline
Solubility: 2.5 mg/mL; 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; 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 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.
