Uses:
Amine-PEG36-acid (NH2-PEG36-COOH) is a PEG derivative containing an amino group and a terminal carboxylic acid. The amino groups can react with carboxylic acids, activated NHS esters, carbonyl groups (ketones, aldehydes), etc. Terminal carboxylic acids can react with primary amine groups in the presence of activating agents such as EDC or DCC to form stable amide bonds. Amine-PEG36-acid can be used to develop antibody-drug conjugates (ADC), and it can also acts as PROTAC linker that can be used in the synthesis of PROTACs.
Amino-PEG36-acid has several advantages over similar amino acids used as spacers, such as:
- Uniform PEG chain length and molecular weight;
- Easy characterization and high purity;
- Higher water solubility and increased hydrodynamic volume of the conjugate molecule;
- Non-antigenic/non-immunogenic properties;
Biopharma PEG provides high purity monodisperse (discrete) PEG with an extensive variety of functional groups(such as Amine-PEG36-Acid), from grams to kilogram, even tons batch size in both non-GMP and GMP grades.
