使用(+)-Biotin 4-nitrophenyl ester may be used in the preparation of biotin tagged ARC (adenosine-oligoarginine conjugate) derivative during cellular protein uptake studies. It may also be used to prepare biotinylated quinazoline derivatives, which shows inhibitory activities against VEGFR-2 (vascular endothelial growth factor receptor-2) tyrosine kinase. (+)-Biotin 4-nitrophenyl ester undergoes hydrolysis in the presence of Na[17O]H to form [17O2]biotin, which can be used in solid-state 17O NMR spectroscopic experiments to analyze large protein-ligand complexes.
一般的な説明The BNP Enzyme Immunoassay (EIA) Kit is an in vitro quantitative assay for detecting BNP peptide based on the principle of Competitive Enzyme Immunoassay.
純化方法The ester has been recrystallised by dissolving 2g in 95% EtOH (30mL), heated to dissolve, then cooled in an ice-water bath. The crystals are collected, washed with ice-cold 95% EtOH (5mL) and dried over P2O5. The RF on silica plates (CHCl3/MeOH 19:1) is 0.19 [Bodanszky & Fagan J Am Chem Soc 99 235 1977].
