PEG500 (Polyethylene glycol 500) is a versatile polymer that's used as a solvent, dispersant, lubricant, and more in industries like pharmaceuticals and biotechnology, and it can also modify liposomes. PEG500 is commonly used as a solvent or carrier for drugs, helping with capsule endoscopy to improve image quality and cecum completion rates[1][2].
The FDA has approved polyethylene glycol (PEG) for use as a carrier or matrix in food, cosmetics and pharmaceuticals, including injectable, topical, rectal and nasal formulations. PEG is virtually non-toxic and can be completely eliminated from the body via the kidneys (for PEG <30 kDa) or feces (for PEG >20 kDa). PEG is non-immunogenic, and antibodies against PEG are only produced in rabbits when PEG binds to highly immunogenic proteins[3].

FDA 已批准聚乙二醇 (PEG) 在食品、化妆品和药物中用作载体或基质,包括可注射、局部、直肠和鼻腔制剂。PEG 几乎没有毒性,可以通过肾脏 (对于 PEG<30 kDa) 或粪便 (对于 PEG>20 kDa) 完整地从体内清除。PEG 缺乏免疫原性,只有当 PEG 与高免疫原性蛋白结合时,兔体内才会产生针对 PEG 的抗体。

计算结果:
工作液浓度: mg/ml;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL saline,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
3. 以上所有助溶剂都可在 GlpBio 网站选购。
