BroadPharm developed a series of ADC linkers with water soluble PEG spacer

The useful characteristics of PEG Linkers have been increasingly recognized in bioconjugation, biolabeling and ADC research & development due to their water solubility, lack of toxicity and well- defined chain lengths. BroadPharm has recently developed a series of ADC linkers with water soluble PEG spacer of various lengths to further empower antibody drug conjugates and other drugs development research.

BroadPharm is a leading customer-focused biotech company in San Diego, California. We are dedicated to manufacturing and supplying high quality PEG linkers, Click Chemistry reagents and advanced Bio-labeling reagents to our clients worldwide. With more than 1,700 PEGylation reagents in stock, BroadPharm is a large supporter of ADC drug development and will continue to provide high quality products to its industry partners.

Please check out our ADC Conjugation Linkers on our website.

Additional ADC linkers can also be made to order. Please contact us with any special inquiries and we will provide a quote.

Advanced New Drug from Nektar with a Short-chain PEG

Nektar Therapeutics is advancing a new drug NKTR-181 to a Phase III clinical trial, which uses polymer chemistry to reach an elusive public health goal: relief from chronic pain with little potential for abuse.

This new drug approach is to covalently bond, through an ether linkage, a short-chain PEG to a five-ring morphinan. The resulting molecule can cross the blood-brain barrier slowly, preventing the “rush” that abusers seek.

BroadPharm provides a broad spectrum of monodispersed, high purity PEGylation reagents which can be used for conjugation of small molecules, peptides and proteins, resulting in prolonged stability, increased water solubility and lower immunogenicity.

BroadPharm has filed a new non-provisional US patent for PEGylated cyanines.

BroadPharm, a leading customer-focused biotech company, has filed a new patent which covers functionalized PEGylated cyanine compounds and their applications. The incorporation of PEG into cyanine dyes has greatly improved the dye’s hydrophilicity. The introduction of a variety of functional groups broadens the applications of these cyanine dyes in biolabeling, imaging and other fields.

“The filing of this new patent will further strengthen BroadPharm's leading position in PEGylation and biolabeling field.” said David Zhang, Chief Executive Officer of BroadPharm.
