DSPE-TK-PEG-SH

DSPE-TK-PEG-SH consists of DSPE, a PEG spacer, a thioketal (TK) linker, and a terminal Thiol group. The thioketal linker is specifically cleavable by reactive oxygen species (ROS) prevalent in inflammatory and tumor microenvironments. This allows for ROS-triggered release of the thiol-conjugated moiety or the PEG shell. The thiol group enables initial conjugation, making this product ideal for designing advanced drug delivery systems that respond to pathological oxidative stress. Please note that this product is intended for research purposes only.

Customer Review

Creatibe Biolabs' custom LNP was the only solution that successfully delivered our CRISPR-Cas9 payload across the blood-brain barrier with high efficiency and low toxicity.”

Dr. Evelyn Reed

Postdoctoral Researcher, Leading University

Our siRNA candidate was failing due to off-target toxicity, but Creatibe Biolabs' team rapidly redesigned our LNP using their modular platform, rescuing our preclinical program.”

Ben Carter

Project Manager

Achieving cytosolic delivery of our protein degrader with Creatibe Biolabs' exosome platform was the key to unlocking our candidate's full therapeutic potential.”

Dr. Kenji Tanaka

Principal Scientist, Large Pharma Corp

Our oncology drug's efficacy was limited by poor tumor accumulation. Creatibe Biolabs' peptide-conjugated liposomes provided the precise targeting we needed, dramatically increasing the drug's therapeutic index.”

Dr. Clara Schmidt

Senior Scientist, Oncology Innovations Inc.

We required a delivery system that would only release its payload in the tumor's acidic microenvironment. Creatibe Biolabs' pH-responsive liposomes performed flawlessly, minimizing systemic exposure.”

David Chen

Formulation Scientist

Outstanding expertise in antibody engineering.The team's attention to detail and innovative approaches have sianificantly accelerated our development timeline.
