ELISA/CLIA Sample and Standard Diluent: Stabilizes proteins with 1.00% BSA and reduces nonspecific binding with 0.05% Tween-20 in PBS (135 mM NaCl, 2.7 mM KCl, 4.3 mM Na₂HPO₄, 1.4 mM KH₂PO₄).

Antibody/Conjugate Diluent: Optimizes capture/detection antibody and HRP/AP conjugate performance while minimizing background.

Plate Blocking and Reagent Diluent: Serves as a blocking buffer and diluent on ELISA plates to prevent nonspecific adsorption.

Immunoassay Wash Buffer: Functions as a gentle wash to lower background via 0.05% Tween-20 while maintaining ionic strength with PBS.

Western Blot Antibody Diluent/Blocking: Dilutes primary/secondary antibodies and blocks membranes to reduce nonspecific binding.

Immunofluorescence/IHC Antibody Diluent: Stabilizes antibodies and decreases off-target binding during tissue/cell staining.

Lateral Flow Assay Diluent: Enhances assay consistency by reducing matrix effects and nonspecific interactions.

Bead-Based Multiplex Assays (e.g., Luminex): Used as a sample and reagent diluent to minimize bead aggregation and background.

Protein/Antibody Stabilization During Dilution: Preserves activity and prevents surface adsorption during sample prep.

General Diagnostic Reagent Diluent: Provides consistent ionic strength and surfactant/protein additives for robust assay performance.
