Medchemexpress LLC Endo-BCN-PEG2-C2-NHS ester | 2243565-12-8 | 95.0% | C22H30N2O8 | 10MG
endo-BCN-PEG2-C2-NHS ester is a PEG-based bifunctional linker for PROTAC construction and bioconjugation. It combines a strained endo-bicyclononyne (BCN) for copper-free click chemistry with an N-hydroxysuccinimide (NHS) ester for selective amine coupling, enabling efficient assembly of bifunctional molecules and protein labeling.
- Contains endo-bicyclononyne (BCN) for strain-promoted azide-alkyne cycloaddition
- Includes an N-hydroxysuccinimide (NHS) ester for rapid amine conjugation
- Incorporates a PEG2 spacer to improve solubility and reduce steric hindrance
- Suitable for PROTAC linker synthesis and bioconjugation workflows
- Molecular formula C22H30N2O8 and molecular weight 450.48 g/mol
Medchemexpress LLC Biotin-peg6-mal | 1808990-66-0 | 99.0% | C31H51N5O11S | 10MG
Biotin-PEG6-Mal is a biotin-labeled polyethylene glycol (PEG6) maleimide linker that enables thiol-selective conjugation to introduce a biotin affinity tag for capture or detection using streptavidin/avidin systems. It is commonly used in PROTAC assembly and bioconjugation workflows where solubility and specific thiol reactivity are required.
- Thiol-selective maleimide group for rapid, specific conjugation.
- PEG6 spacer improves solubility and reduces steric hindrance.
- Biotin affinity tag enables high-affinity streptavidin/avidin capture.
- High purity supports reproducible experimental results.
- Stable as a powdered reagent with defined cold-storage recommendations.
