- In addition to the AP Mutein, recombinant the lyophilizate contains a mixture of proteins from the Pichia system supporting the interference elimination. AP Mutein is lyophilized from a solution containing in NaCl, 0.2 mol/L; ZnCl2, 0.1 mmol/L; Tea, 30 mmol/L; MgCl2, 1 mmol/L; raffinose, 50% (w/v); pH approximately 7.6. Production is established according to the procedures of the active enzyme.
- Use Alkaline Phosphatase Mutein (AP Mutein) to eliminate human serum derived AP directed assay interferences.
