PEG

m-PEG37-hydrazide is a PEG linker containing a hydrazide end group. Hydrazine moieties react with an aldehyde to form semi-permanent hydrazone bonds. The hydrophilic PEG chain increases the water solubility of the compound. Longer PEG chains have better solubility properties relative to shorter PEG chains. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Amino-PEG7-Amine is a crosslinking reagent containing two amino groups. Amino(NH2) groups are reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Bis-PEG11-acid is a PEG linker containing two terminal carboxylic acid groups. The hydrophilic PEG spacer increases solubility in aqueous media. The terminal carboxylic acids can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Bis-PEG10-NHS ester is a PEG linker containing two NHS ester groups. The hydrophilic PEG spacer increases solubility in aqueous media. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Amino-PEG7-alcohol is a PEG reagent containing an amino group (NH2) and a hydroxyl group. The amino group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Amino-PEG10-alcohol is a highly water soluble PEG reagent. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

2-(t-Butoxycarbonylamido)-1,3-bis(PFP-oxycarbonylethoxy)propane contains a Boc protected amino group and two PFP end groups. PFP group can react with primary amines to form a stable amide bond. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Amino-PEG2-CH2CO2H is a PEG compound containing an amino group with a terminal carboxylic acid. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Azide-PEG12-alcohol is a PEG linker with a click chemistry azide group. The compound is soluble in aqueous media. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
