Durastab™ Protein-free Plate Sealer for stabilizing antigen, antibody-coated plates/ tube/ slide to provide ultra-long drying stability. At the same time, specific components can reduce non-specific reactions, improve the signal-to-noise ratio of detection, avoid high background and false positives, and make the test results more accurate.
Art no: PFPS
Package size: 100mL, 1L, bulk
Buffer: PBS
pH value: 7.0±0.4
Protein: None
Shelf life: 3 years
Storage: 2-8℃

Art no: PFPS
Package size: 100mL, 1L, bulk
Buffer: PBS
pH value: 7.0±0.4
Protein: None
Shelf life: 3 years
Storage: 2-8℃
Application:
ELISA：Use as coated antibody, antigen and other active materials are dried.
Microarray：Use as the microarray antibody, antigen components are dried.
Lateral chromatography：Use as active components such as Conjugates on the conjugate pad and protein were dried.
Instruction:
Durastab™ Ultra Plate Sealer is a ready-to-use reagent, Shake well use after the equilibration to the reaction temperature.
Microplate Stabilization Procedure (Example):
1. Cover and seal with antigen or antibody;
2. Wash: Wash away the excess blocking solution with PBS / TRIS washing buffer (recommended without surfactant), Repeat twice;
3. Stable: add appropriate Durastab™ Protein-free Plate Sealer, 20-37℃ for a certain time;
4. Dry: after suction (or drying) Durastab™ Protein-free Plate Sealer, Fully drying in drying box (20-37℃) for 2-6 hours;
5. Storage: recommended packaging plates using seal bag with good air tightness, And put in the desiccant, Stored at 2-8℃, Usually, it can be stored refrigerated for more than two years; It can also be stored at room temperature for several months after packaging.
Durastab™ Protein-free Plate Sealer has a good sealing effect, and can also omit the conventional sealing steps. It is recommended to test the suitability of the different reaction systems.

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.
