Medchemexpress LLC Propargyl-PEG7-NHS ester | 2093152-77-1 | MFCD29041936 | >95.0% | 489.51 g/mol | C22H35NO11 | 1 G
Propargyl-PEG7-NHS ester is an alkyne-functional PEG7 N-hydroxysuccinimide (NHS) ester used as a bifunctional linker for bioconjugation. It couples to primary amines via NHS chemistry and provides a terminal alkyne for copper-catalyzed azide-alkyne cycloaddition, making it suitable for ADC, PROTAC, and general labeling applications.
- Alkyne-functional terminal enables click chemistry.
- NHS ester reacts with primary amines for covalent coupling.
- PEG7 spacer increases solubility and provides flexibility.
- Molecular weight about 489.51 g/mol and formula C22H35NO11.
- Typical applications include ADC linkers, PROTAC synthesis, and peptide or protein labeling.
Apexbio Technology LLC O-propargyl-puromycin (OPP)(Synonyms: OP-puromycin, Propargyl-puromycin, Puromycin alkyne, Alkyne-puromycin), 1mg, CAS: 1416561-90-4.
O-propargyl-puromycin (OPP CAS 1416561-90-4) is an alkyne-functionalized derivative of puromycin commonly utilized to detect and quantify newly synthesized proteins It incorporates into nascent polypeptides by acting as a translation terminator covalently attaching to their C-terminal ends Subsequent detection occurs through azide-alkyne cycloaddition under copper(I) catalysis facilitating visualization or isolation of actively produced proteins In cellular and animal models OPP labeling enables measurement of global protein synthesis rates and assessment of responses to various stimuli or stress conditions contributing significantly to proteomics and cell biology research
Apexbio Technology LLC Propargyl-PEG2-acid 1859379-85-3 5g
Propargyl-PEG2-acid (CAS 1859379-85-3) is a polyethylene glycol (PEG)-based small molecule featuring a terminal propargyl (alkyne) group and a carboxylic acid moiety The alkyne functionality facilitates copper-catalyzed azide-alkyne cycloaddition (CuAAC) reactions commonly referred to as click chemistry This enables site-specific conjugation to azide-containing molecules for the synthesis of bioconjugates such as antibody-drug conjugates (ADCs) labeling probes or other functionalized biomolecules Its PEG2 spacer increases solubility and flexibility supporting its application in biomedical research requiring stable and efficient heterobifunctional linkers
