Medchemexpress LLC Biotin-PEG3-alcohol | 1263044-40-1 | >97.0% | C16H29N3O5S | 10MG
Biotin-PEG3-OH is a biotinylated, hydroxy-terminated triethylene glycol (PEG3) linker used to introduce a biotin affinity tag into small molecules, peptides, and PROTAC constructs for chemical biology research. It is supplied as a waxy solid and is commonly used in affinity labeling, pull-down assays, and conjugation chemistry; follow supplier guidance for cold, dry storage.
- Provides biotin tag for streptavidin-based capture
- Peg3 spacer improves solubility and reduces steric hindrance
- Terminal hydroxyl enables further chemical modification
- Suitable for PROTAC linker synthesis and conjugation
- Typical purity >97.0% and stable when stored at -20 °C
Medchemexpress LLC Biotin pentafluorophenyl ester | 120550-35-8 | 97.0% | 100 MG
Biotin pentafluorophenyl ester is a biotinylated activated ester used to introduce a biotin affinity tag through reaction with nucleophiles. It serves as an alkyl/ether-based PROTAC linker and reagent for biotinylation in chemical biology and proteomics workflows.
- Activated pentafluorophenyl (PFP) ester for efficient coupling to amines and alcohols.
- Introduces a biotin handle for streptavidin-based capture and detection.
- Useful in PROTAC linker assembly, probe synthesis, and affinity enrichment.
- Supplied as a white to off-white solid with molecular weight 410.36 g·mol⁻¹.
