Description

PLGA (75:25) is a low toxicity, biocompatible and biodegradable controlled drug delivery carrier, can achieve slow release in the organism. PLGA (75:25) is a copolymer of 75% poly lactic acid (PLA) and 25% poly glycolic acid (PGA). PLGA (75:25) has been extensively studied as delivery vehicles for agents, proteins and various other macromolecules such as DNA, RNA and peptides[1][2][3].

In Vitro

PLGA (75:25) (0.03-5 mg/mL; 72 h) only affects the viability of Calu-3 cells at concentrations that are too high for clinical use[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Viability Assay[1]

Cell Line: Calu-3 cells
Concentration: 0.03-5 mg/mL (for PLgA (75:25)/PVA and PLgA (75:25)/CS); 3-5 mg/mL (for PLgA (75:25)/CS and PLgA (75:25)/PF68); 0.03-1 mg/mL (for PLgA (75:25)/PVA and PLgA (75:25)/PF68) (CS (chitosan), PF68 and PVA (poly vinyl alcohol) serve as cationic stabilizer)
Incubation Time: 72 h
Result: Showed low toxicity to cells (cell viability was always higher than 50%) even at the highest concentration tested, when xposured to PLgA (75:25)/PVA, PLgA (75:25)/CS and PLgA (75:25)/PF68 nanoparticles.
Increased cell viability, after short exposure (4 hours) to PLGA/PF68 nanoparticles.
In Vivo

PLGA (75:25) (40 mg/kg Risperidone (PLGA (75:25) as a drug delivery carrier); s.c.; single) shows a good activity of sustained drug release for 45 days[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Male Sprague-Dawley rats[2].
Dosage: 40 mg/kg (dose of Risperidone, PLGA (75:25) as a drug delivery carrier).
Administration: Subcutaneous injection; single.
Result: Achieved slow release in vivo: after an initial burst, a sharp drop occurred and the drug levels through day 22 remained in a steady manner while progressing to a decline up to day 45.

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.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 5 mg/mL; Clear solution

    This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
