Medchemexpress LLC BCN-PEG3-biotin | 1263166-92-2 | 95.0% | 594.76 | C29H46N4O7S | 100 MG
BCN-PEG3-biotin is a click-chemistry linker containing a bicyclononyne (BCN) group, a three-unit polyethylene glycol spacer, and a terminal biotin. It is used for strain-promoted alkyne-azide cycloaddition (SPAAC) with azide-containing molecules and as a biotin tag for affinity capture or detection.
- Facilitates copper-free SPAAC click reactions.
- Three-unit PEG spacer improves solubility and reduces steric hindrance.
- Terminal biotin enables streptavidin-based capture and detection.
- Supplied as an off-white to light yellow solid with ≥95.0% purity.
- Soluble in DMSO (100 mg/mL); powder storage recommended at -20°C.
Lumiprobe TAMRA DBCO 5-isomer 5mg
This product is a derivative of tetramethylrhodamine (TMR, TAMRA) containing a cyclooctyne moiety (dibenzocyclooctyne, DBCO). Pure 5-isomer.DBCO reacts quickly and efficiently with azides by simply mixing the components without the need for a copper catalyst (so-called sterically promoted cycloaddition reaction (SPAAC)).TAMRA DBCO can be used for the labeling of proteins, peptides, nucleic acids, and other molecules containing azide groups. TAMRA is often used as a FRET acceptor for FAM fluorophore. Can replace DyLight 549.
