Q1: What does the Ultra Plate Sealer do?
A: It stabilizes coated ELISA plates for long-term dry storage, protecting coated antibody/antigen activity - a direct-use option for kit makers seeking dry-format plate stability.
Q2: What does a beads stabilizer prevent?
A: It prevents aggregation of coated magnetic beads and preserves binding capacity during storage, which is critical for automated CLIA systems using magnetic microparticles.
Q3: How do I choose between PBS, TRIS and protein-free versions?
A: Match your assay buffer (BSPB/BSTR families) and choose the protein-free (PF) versions when animal proteins cannot be tolerated in the formulation.
Q4: Can plate sealer replace wet-format plate storage?
A: It enables dry-format storage of coated plates after validation; compare accelerated and real-time stability data of your coated plates with and without the sealer.
Q5: Can Beads Stabilizer PBS-PF replace my current magnetic beads stabilizer?
A: Yes. Beads Stabilizer PBS-PF is designed to prevent aggregation of coated magnetic beads and preserve binding capacity during storage in CLIA workflows. Exchange it at the same ratio in your bead reagent, then compare bead dispersion, binding capacity and non-specific signal against your current stabilizer over accelerated storage.
