Stabilizers & diluents for conjugates

Diluents and Stabilizers for antibodies and Horseradish peroxidase and Alkaline phosphatase conjugates

Horseradish Peroxidase (HRP) and Alkaline Phosphatase (AP) are the most commonly used enzymes in immunoassays. In order to be used in the assay, HRP and AP molecules must first be conjugated to the detection antibody or antigen. The antibodies or antigens conjugated with HRP or AP can be stored at 2-8°C either as a concentrated stock solution or diluted in an appropriate buffer to the desired assay dilution factor.

When diluted biomolecules or conjugates need to be stored for future use, these buffers should also have stabilizing properties to maintain the molecular conformation and prevent loss of activity over time, finally providing ready-to-use working dilutions. Kem-En-Tec Diagnostics offers a series of different conjugate stabilizers with a stability life time of up to 4 years.

  • BSA free
  • Free of azide, mercury or other toxic preservatives
  • Ready-to-use
  • Negligible batch-to-batch variations

HRP-StabilPLUS suitable for the dilution and stabilization of HRP-conjugates
AP-StabilPLUS suitable for the dilution and stabilization of AP-conjugates
UNI-StabilPLUS suitable for the dilution and stabilization of both HRP- and AP-conjugates
Antibody Enhancer also able to enhance the binding capacity of the diluted antibodies for increased sensitivity
