Please contact Technical Support @ [email protected] for assistance in finding alternative.


Biotin (Long Arm) NHS, water soluble, is a sulfonated derivative of our Biotin (Long Arm) NHS. Like Biotin (Long Arm) NHS, this reagent is useful for attaching biotin to proteins or other molecules containing a primary amino group. The spacer arm allows full accessibility of attached biotins by avidin derivatives or complexes. Unlike Biotin (Long Arm) NHS, this derivative is completely water soluble, and does not require DMF or DMSO to dissolve the activated biotin.
