Zeta Antibody Diluent is provided as a ready-to-use (Tris Buffered) diluent for diluting primary antibodies and for use as a negative control. Both monoclonal and polyclonal antibodies are stabilized for long-term storage thereby reducing the number of titrations required from concentrated form. This product contains a highly purified carrier proteins that minimizes proteolytic enzyme degradation, a wedding reagent to reduce surface tension, and an anti-microbial agent (ProClin) to prevent microbial growth. Not for antibodies that have been conjugated with peroxidase. In most cases, antibodies diluted in this reagent can be stored for 24 months at 2-8°C. Refer to individual datasheet for storage information specific to each antibody. Diluent is subjected to 0.2 micron filtration.
