Durastab™ Protein-free AP Stabilizer is an alkaline phosphatase (AP) conjugate dilution/stabilizer, used to prepare AP working solutions that remain stable during long-term storage at 2–8 °C. This product contains no protein components, preventing inter-protein cross-reactivity.
Durastab™ Protein-free AP Stabilizer is an alkaline phosphatase (AP) conjugate dilution/stabilizer, used to prepare AP working solutions that remain stable during long-term storage at 2–8 °C. This product contains no protein components, preventing inter-protein cross-reactivity.
Application:
ELISA / Chemiluminescence: For diluting AP-labeled detection antibodies.
Western blot / Microarray / IHC: Used as the diluent for AP-conjugated secondary antibodies.
Instruction:
Durastab™ Protein-free AP Stabilize is ready-to-use and should be equilibrated to the reaction temperature before application.
Prepare the AP working solution by diluting the AP conjugate to the desired concentration according to the user-defined dilution ratio.
It is recommended to validate performance within specific assay systems prior to full-scale use.
Store at 2-8 °C.
For research use only or for further use in the production of detection kits. Not for human or animal use!
Q1: What does an AP stabilizer do?
A: It preserves alkaline phosphatase conjugate activity in solution during storage, protecting enzyme conformation and activity so coated conjugates keep performance over their shelf life.
Q2: Which AP stabilizer version matches my buffer system?
A: APST for standard PBS-based systems, APTR for TRIS-based systems, APME for MES-based systems, and APPF (protein-free) when the formulation must be free of animal proteins.
Q3: Can AP stabilizer be used with both polyclonal and monoclonal AP conjugates?
A: Yes. It is compatible with AP-labeled antibodies and other AP conjugates; confirm long-term stability with your own conjugate under intended storage conditions.
Q4: Storage conditions for the stabilizer itself?
A: Store at 2-8 °C and protect from contamination; the stabilizer is supplied ready to use.
Q5: Can Protein-free AP Stabilizer replace my current AP conjugate stabilizer?
A: In most formulations, yes. Protein-free AP Stabilizer is a ready-to-use diluent that preserves alkaline phosphatase conjugate activity during storage; replace your current stabilizer at the same volume fraction and validate with accelerated stability on your own conjugate. PBS, TRIS, MES and protein-free versions let you match your existing buffer system.
