 | Hazard Information | Back Directory |  | [Description] 
 PC Biotin-PEG3-alkyne is useful for introducing a biotin moiety to azide-containing biomolecules using Cu(I)-catalyzed Click Chemistry. PEG spacer provides better solubility to the labeled molecules in aqueous media. Captured biomolecules can be efficiently photoreleased using near-UV, low intensity lamp (e.g. 365 nm lamp at 1-5 mW/cm2).
 |  | [Uses] 
 PC biotin-alkyne is an azide-reactive photoclevable biotin probe that allows for reagent-free release of the captured biomolecules from streptavidin. This reagent contains a biotin moiety linked to an alkyne group through a spacer arm containing a photocleavable moiety. Captured biomolecules can be efficiently photoreleased, typically >90% in 5-25 minutes using an inexpensive, near-UV, low-intensity lamp (e.g. 365 nm lamp at 1-5 mW/cm2).
