Ac-pSar12-OH
Based on 1 Customer Validation
Ac-pSar12-OH is a water-soluble polymer of the polysarcosine class and can be used as a linker. Ac-pSar12-OH is a linear polypeptide derivative composed of 12 arginine units. Ac-pSar12-OH N-terminus is modified with an acetyl group, while the C-terminus retains a free hydroxyl group, which can help enhance the stability of the polypeptide.
