GalNAc-Lipid GL3
GalNAc-Lipid GL3 is a first-generation GalNAc-based ligand designed for targeted delivery of therapeutic agents to hepatocytes via the asialoglycoprotein receptor (ASGPR). It features a trivalent GalNAc structure attached to a TRIS scaffold, which facilitates efficient binding to ASGPR and subsequent cellular uptake. In preclinical studies, GalNAc-Lipid GL3 was formulated into lipid nanoparticles (LNPs) and tested for its ability to deliver CRISPR base editors to the liver. While effective, GL3 demonstrated lower editing efficiency compared to its second-generation counterpart, GalNAc-Lipid GL6, which achieved higher liver editing rates in both LDLR-deficient and wild-type mice. This suggests that GL3's TRIS scaffold may be less optimal than the lysine-based scaffold used in GL6 for ASGPR-mediated uptake and delivery. Despite this, GalNAc-Lipid GL3 remains an important reference in the development of targeted liver delivery systems, highlighting the potential of GalNAc ligands for non-LDLR-dependent therapies. Grade: >98%.
GalNAc-Lipid GL5
GalNAc-Lipid GL5 is a targeting ligand designed for lipid nanoparticles (LNPs) with a short 12-unit PEG linker. It enables non-LDLR (low-density lipoprotein receptor)-dependent delivery of therapeutic agents to hepatocytes. However, compared to GL6 with a longer PEG linker, GL5 exhibits lower liver-targeting efficiency. For instance, in experiments targeting the _Angptl3_ gene in mice, GL5 achieved only 18% liver editing efficiency, while GL6 reached 56%. This suggests that the shorter PEG linker in GL5 may limit its binding affinity to ASGPR (asialoglycoprotein receptor) on hepatocytes. Despite its lower efficiency, GL5 remains valuable for understanding the structure-function relationship in GalNAc-LNP design. Grade: ≥98%.
GalNAc-Lipid GL6
GalNAc-Lipid GL6 is a potent and scalable ligand designed for targeted liver delivery of therapeutic agents, particularly in the context of CRISPR base editing therapies. It features a multi-valent N-acetylgalactosamine (GalNAc) structure that binds specifically to the asialoglycoprotein receptor (ASGPR), enabling efficient uptake by hepatocytes. This ligand is part of the second-generation GalNAc design, which incorporates a lysine-based scaffold and a longer PEG spacer (34-38 units) compared to earlier designs. The combination of a 1,2-O-dioctadecyl-sn-glyceryl (DSG) lipid anchor and the optimized PEG spacer enhances the stability and delivery efficiency of lipid nanoparticles (LNPs) in vivo. In preclinical studies, GalNAc-Lipid GL6 demonstrated superior performance in liver-targeted gene editing compared to other GalNAc ligands, achieving high editing rates in both wild-type and LDLR-deficient mice and non-human primates. This ligand has shown significant potential for non-LDLR-dependent delivery of CRISPR therapies, making it a valuable tool for treating genetic disorders and metabolic diseases. Grade: 98%.
GalNAc-Lipid GL7
GalNAc-Lipid GL7 is a ligand designed to optimize the delivery of lipid nanoparticles (LNPs) to hepatocytes via non-LDLR (low-density lipoprotein receptor) dependent pathways. It is based on Design 2, which features a lysine scaffold with three GalNAc units attached through a 36-unit PEG linker. The primary goal of GL7 is to evaluate the impact of different lipid anchors on the stability and delivery efficiency of LNPs. Specifically, GL7 incorporates a cholesteryl (Chol) lipid anchor, which was tested alongside other lipid anchors like 1,2-O-dioctadecyl-sn-glyceryl (DSG) and arachidoyl (C20) to assess their effects on ASGPR (asialoglycoprotein receptor) recognition and binding. However, experiments in Ldlr-mice demonstrated that the DSG lipid anchor in GL6 was significantly more effective for liver-targeted gene editing compared to the cholesterol anchor in GL7, with an editing efficiency of 56% for DSG versus 4% for cholesterol. This suggests that GL7, with its cholesterol anchor, is less efficient for non-LDLR-dependent delivery of LNPs to hepatocytes. Grade: ≥98%.
GalNAc-Lipid GL9
GalNAc-Lipid GL9 is a ligand designed for lipid nanoparticles (LNPs) to facilitate non-LDLR (low-density lipoprotein receptor)-dependent delivery of therapeutic agents to hepatocytes. It is based on Design 2, which uses a lysine scaffold with three GalNAc units attached through a PEG linker. The primary goal of GL9 is to evaluate the impact of different lipid anchors on the stability and delivery efficiency of LNPs. In GL9, the lipid anchor is an arachidoyl (C20) moiety, which was tested alongside other lipid anchors like 1,2-O-dioctadecyl-sn-glyceryl (DSG) and cholesterol (Chol) to assess their effects on ASGPR (asialoglycoprotein receptor) recognition and binding. However, experiments in LDLR-deficient mice demonstrated that the DSG lipid anchor in GL6 was significantly more effective for liver-targeted gene editing compared to the arachidoyl (C20) anchor in GL9. Specifically, the editing efficiency of GL6 with DSG was 56%, while GL9 with C20 achieved only 8% efficiency. This indicates that GL9, with its C20 lipid anchor, is less efficient for non-LDLR-dependent delivery of LNPs to hepatocytes. Grade: ≥98%.
GalNAc-NAG-25 Phosphoramidite
GalNAc-NAG-25 Phosphoramidite is a modified phosphoramidite that incorporates a N-acetylgalactosamine (GalNAc) moiety linked to the NAG component, specifically designed for the synthesis of oligonucleotides.

GalNAc-PEG-Cluster-1-CPG
GalNAc-PEG-Cluster-1-CPG is a specialized reagent used for the synthesis of oligonucleotide conjugates, particularly for liver-targeted drug delivery. It combines N-acetylgalactosamine (GalNAc) with a polyethylene glycol (PEG) linker and a controlled pore glass (CPG) support to facilitate the attachment of GalNAc clusters to oligonucleotides. This structure enhances the targeting of siRNA or other nucleic acid drugs to hepatocytes via the asialoglycoprotein receptor (ASGPR), improving cellular uptake and therapeutic efficacy. Grade: ≥98%.
