生物活性

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].

体外研究
(In Vitro)

PLGA 75:25 (0.03-5 mg/mL；72 小时) 仅在浓度过高而无法用于临床时影响 Calu-3 细胞的活力[1]。

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.
体内研究
(In Vivo)

PLGA 75:25 (40 mg/kg Risperidone (PLGA 75:25 as a drug delivery carrier)；sc；single) 具有良好的45天缓释活性[2]。

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.

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.
