硬脂酸聚乙二醇琥珀酰亚胺酯外观呈白色或类白色固体或者半固体；PEG的分子量有2000、3400和5000，通常以水、Chloroform和DMSO作为溶剂，在水中有很好的的溶解性；可以通过疏水作用力锚定在细胞膜表面，SA-PEG-NHS硬脂酸聚乙二醇琥珀酰亚胺酯对光和温度敏感，为了获得使用效果，材料应始终在干燥条件下保持低温，避免经常解冻和冻结。
SA-PEG-NHS硬脂酸聚乙二醇琥珀酰亚胺酯应储存在4℃以下低温、避光，干燥处，可以在惰性气体下处理材料可以获得较好的稳定性。
The appearance of stearic acid polyethylene glycol succinimide ester is white or almost white solid or semi-solid; The molecular weight of PEG is 2000, 3400 and 5000. Usually, water, chloroform and DMSO are used as solvents and have good solubility in water; It can be anchored on the cell membrane surface by hydrophobic force. Sa-peg-nhs stearic acid polyethylene glycol succinimide ester is sensitive to light and temperature. In order to obtain the use effect, the material should always be kept at low temperature under dry conditions to avoid frequent thawing and freezing.
Sa-peg-nhs stearic acid polyethylene glycol succinimide ester should be stored at a low temperature below 4 ℃, away from light and in a dry place. The material can be treated under inert gas to obtain good stability.
