Earlier this month in May, 2020, the world’s leading chemical supplier Alfa Chemistry announced that a total of close to 800 PEG linker products are now available for its customers worldwide, including acid PEG linkers, alkyl PEG linkers, amino PEG linkers, azido PEG linkers, benzyl PEG linkers, biotin PEG linkers, fmoc PEG linkers, NHBoc PEG linkers, NHS ester PEG linkers, t-butyl ester PEG linkers, Thp peg linkers, and other PEG Linkers.
Polyethylene glycol (PEG) linkers are necessary for bioconjugation and pegylation. Due to their characteristics of water solubility, lack of toxicity, low immunogenicity, well defined chain lengths and molecular weights, PEG linkers are widely used in pharmaceutical and biotechnology applications.
PEGylation is considered one of the most successful techniques to enhance the therapeutic and biotechnological potential of molecules, such as therapeutic peptides, proteins, small molecules, oligonucleotides, and antibodies. The PEG based products differs from one another because they have different linker lengths and various reactive groups. Usually, PEG linkers contain a methoxy group and another functional group. And it is said that all common target moieties can be specifically addressed with the appropriate functionalized PEG linker.
The comprehensive portfolio of PEG linkers at Alfa Chemistry can be further divided into the following subtypes:
-Acid PEG linkers
-Alkyl PEG linkers
-Amino PEG linkers
-Azido PEG linkers
-Benzyl PEG linkers
-Biotin PEG linkers
-Fmoc PEG linkers
-NHBoc PEG linkers
-NHS ester PEG linkers
-t-butyl ester PEG linkers
-THP PEG linkers
-Other PEG Linkers
“The high purity PEGylation products we offered are kept in stock, with a hope to empower our clients’ research on bioconjugation, PEGylation, crosslinking, as well as ADC drug development and biolabeling in the pharmaceutical and biotech area,” says a senior scientist from Alfa Chemistry.
