TCO-PEG2-acid
This product is a heterobifunctional linker featuring a trans-cyclooctene (TCO) group for ultrafast tetrazine ligation and a terminal carboxylic acid for amide coupling. The PEG2 spacer improves solubility and compact flexibility, making it especially effective for bioorthogonal labeling, probe development, and drug delivery.
Key Features and Benefits:
-
TCO Group: Enables rapid, copper-free IEDDA ligation with tetrazines.
-
Carboxylic Acid: Couples efficiently with amines for stable amide bonds.
-
PEG2 Spacer: Provides solubility and reduced steric hindrance.
-
Dual Reactivity: Combines bioorthogonal and amide conjugation.
-
High Purity: Ensures reliable, reproducible results.
Applications:
-
Bioorthogonal Labeling: Allows ultrafast tetrazine ligation in vitro and in vivo.
-
Probe Development: Builds TCO-functionalized probes for imaging and diagnostics.
-
Drug Delivery: Provides PEGylated scaffolds for targeted therapeutic conjugates.
-
Bioconjugation: Supports multifunctional and orthogonal linker strategies.
Storage and Handling:
-
Storage: Store at –20 °C in a tightly sealed, moisture- and light-protected container.
-
Handling: Use anhydrous solvents (e.g., DMF, DMSO); protect TCO from prolonged light exposure.
This product integrates bioorthogonal TCO reactivity with amine-coupling acid chemistry in a PEG2 scaffold, specifically making it a compact and versatile tool for advanced conjugation.
