BISPYCATCHER2





The reaction is robust at pH 5 to 8, at temperatures from +4°C to +37°C, in various buffer conditions (Ca2+/Mg2+ not needed) and in the presence of detergents. The reaction also occurs inside cells (in vivo). Since the speed of the coupling reaction is concentration dependent, it is recommended to use BiSpyCatcher2 undiluted.
All the different formats of BiSpyCatcher2 are compatible with Bio-Rad's recombinant HuCAL® antibodies with a SpyTag2 at the C-terminus of the heavy chain.

BiSpyCatcher2 (TZC002) is available in two modified versions, BiSpyCatcher2-CYS (TZC002CYS) and BiSpyCatcher-CYS3 (TZC002CYS3), which contain one or three cysteine residues, respectively, for site-specific conjugation by the user.
