New to the family of Seramun stabilizers for HRP antibody conjugates and protein conjugates is the ready-to-use product SeramunStab® STM3. This stabilizing solution is free from harmful organic solvents and thus doesn’t require labelling according to the REACH regulation Annex XVII 0. SeramunStab® STM3 is especially suitable for the long-term stabilization of HRP activity and antibody reactivity at low conjugate concentrations. Other characteristics like having an excellent stabilization effect over a wide temperature range, a very good signal-to-noise ratio, and a shelf life of 36 months from date of manufacture are also a plus.
