产品简介

SiR-BCN is a clickable derivative of SiR. It reacts with tetrazine or azide derivatives and allows the preparation of custom SiR-conjugates.

SiR-BCN is a bicyclo[6.1.0]nonyne (BCN) derivative of the fluorophore silicon rhodamine (SiR). Sir-BCN contains a short PEG linker between the SiR fluorophore and the BCN moiety. SiR-BCN reacts quickly with tetrazine and azide derivatives to form covalent linkages. Small molecules, peptides, oligonucleotides or proteins bearing the appropriate tetrazine or azide can be conjugated to SiR-BCN. SiR excitation and emission are compatible with GFP and/or m-cherry fluorescent proteins. It can be imaged with a standard Cy5 filterset.
