Our Multi-Arm PEG Products 4-Arm PEG-X/Y Bifunctional 4-Arm PEG reagents have two functional groups X/Y with 1:3 ratio or 2:2 ratio. We started offering this series of special reagents as customs synthesis with the following combinations. We are also listing some of these reagents as regular catalog products that are ready to ship overnight. We […]
Is Your Maleimide Thiol Chemistry Stable?
The typical PEG-maleimide-thiol reaction results in thiosuccinimide formation which is reversible, with PEG-maleimide elimination occurring slowly under biologically relevant conditions. The reversed reaction leads to the breakage of the maleimide-thiol linkage and the loss of PEG from the thiol/cysteine-containing molecules. If the maleimide-thiol chemistry does not work for your application, you may consider alternatives with […]

Looking for a better method to improve your PEGylation yield?
Are you looking for a better way to improve your PEGylation yield? I bet you are. What Affects PEGylation Yield? Many parameters affect PEGylation process. The surface accessibility of the reactive site of amino acids is the most critical. On protein surfaces, there exist hydrophobic patches and concaves that expel water and thus hydrophilic PEGs. […]

Liposome Drug Products Chemistry, Manufacturing, and Controls; Human Pharmacokinetics and Bioavailability; and Labeling Documentation Guidance for Industry It provides specific labeling requirements for liposome versus pegylated liposome. The nonproprietary name of a drug product approved under the Federal Food, Drug, and Cosmetic Act is its established name, which , in most instances , will be […]
Nektar – PEGylated Opioid Analgesic Reported Positive Phase 3 Clinical Trial Results
A short polyethylene glycol (PEG) and its pegylation to small molecules could make a huge difference. Nektar announced positive topline results from an oral Human Abuse Potential (HAP) study of NKTR-181, which is a first-in-class opioid analgesic. What Is Nektar? NKTR-181 is a pegylated small molecule drug: a short PEG with six repeating ethylene glycol […]
