R-M2-10000	DMG-PEG-FAM	DMG-PEG2K-FAM is mainly used for fluorescent labeling and tracing of nanocarriers. The PEG segment provides a surface barrier effect, which can reduce the non-specific adsorption of nanoparticles in organisms, while the FAM group can be used to track the distribution, metabolism, and targeting processes of nanoparticles in real time. In biomedical research, such materials are commonly used to construct multifunctional delivery systems, such as combining fluorescent labeling with targeted functions for visual drug delivery and efficacy evaluation.	price>

R-M2-10027	Se-Se-PEG-PSMA-617	The design of Se-Se-PEG-PSMA-617 may aim to utilize the redox sensitivity of selenium selenium bonds to achieve controlled release or activation of drugs in specific environments, such as the tumor microenvironment. This type of molecule may be used for: Prodrug design: Local activation of PSMA-617 is achieved by breaking the Se Se bond, improving the treatment window. Responsive delivery: Combining PSMA targeting with redox responsiveness to achieve tumor specific drug release.	price>
R-M2-10028	Se-Se-PEG-PSMA-11	Se–Se–PEG–PSMA-11 is a PEGylated prostate-specific membrane antigen (PSMA) targeting ligand in which the PSMA-11 moiety is connected to polyethylene glycol (PEG) via a diselenide (Se–Se) linker. Typical Applications: PSMA-targeted nanoparticles or drug delivery systems; Redox-responsive theranostic platforms; Ligand conjugation for prostate cancer imaging (PET/SPECT/optical); Surface modification of liposomes, polymeric NPs, or inorganic NPs.	price>
R-M2-10029	Se-Se-PEG-PSMA-ligand-1	Se–Se–PEG–PSMA-ligand-1 is a PEG-modified prostate-specific membrane antigen (PSMA) targeting ligand engineered with a diselenide (Se–Se) redox-cleavable linker. This design combines selective PSMA receptor binding with controlled, tumor-microenvironment-responsive behavior. Applications: Functionalization of liposomes, polymeric nanoparticles, inorganic nanocarriers; Targeted drug-delivery or theranostic systems for prostate cancer; Construction of stimuli-responsive PSMA-targeting conjugates; Redox-cleavable linkers in nanomedicine, bioconjugation, and radiopharmaceuticals.	price>
R-M2-10032	Se-Se-PEG-PSMA-I&T	Se-Se-PEG-PSMA-I&T is a selenium–selenium (Se–Se) diselenide-linked, PEG-modified PSMA-I&T derivative designed for tumor-targeted delivery with redox-responsive cleavage. PSMA-I&T (“Imaging & Therapy”) is a high-affinity ligand for the prostate-specific membrane antigen (PSMA), widely used in radiotheranostics. Incorporation of a Se–Se redox-cleavable linker makes the conjugate selectively degradable in the reductive tumor microenvironment (high GSH), enabling controlled release of attached cargos. Applications: Targeted delivery systems (nanoparticles, prodrugs, peptides); Redox-responsive PSMA-directed therapeutics; Radiotheranostic development; In vivo tumor targeting studies; Functionalization of drug carriers via Se–Se-PEG linker.	price>
R-M2-10066	DBCO-cRGDyK-PEG2k-Cy3	DBCO-cRGDyK-PEG2k-Cy3 is a functionalized fluorescent dye labeled PEG compound mainly used for the construction of nucleic acid drug delivery systems, targeted delivery enhancement, and biomaterial functionalization.	price>
R-M2-10069	DOTA-PEG8000-Tetrazine	DOTA-PEG8000-Tetrazine has broad potential applications in biomedical research, such as molecular imaging, targeted drug delivery, and surface modification of biomaterials. Its core characteristics include efficient orthogonal biological reactivity, good water solubility and biocompatibility, as well as the "invisible" effect achieved through PEG chains, which helps reduce immune system clearance and improve stability.	price>
R-M2-10070	DOTA-PEG2K-HA35k	DOTA-PEG2K-HA35k/DOTA-PEG2K-Hyaluronic acid35K/DOTA-PEG2000-Hyaluronic acid35000/Hyaluronic acid35K-PEG2000-DOTA is widely used in the biomedical field, including drug delivery, biological imaging (such as PET/SPECT), and surface modification of biomaterials. The PEG2000 chain endows it with good water solubility and biocompatibility, which helps to stabilize circulation in the body. The DOTA group can efficiently chelate metal ions (such as gallium and copper), making it suitable for radiolabeling and molecular imaging. HA35k (hyaluronic acid) endows it with the ability to target CD44 receptors, which can be used for tumor targeted delivery or imaging.	price>
