ELISA Sample Dilution: Dilutes serum, plasma, or cell culture supernatants while minimizing matrix effects and nonspecific binding.

Antibody Diluent (ELISA/EIA): Stabilizes capture and detection antibodies and reduces background during incubations.

Western Blot Antibody Dilution: Serves as a primary/secondary antibody diluent to lower nonspecific interactions and improve signal-to-noise.

Plate Blocking/Incubation Buffer: Supplements or replaces separate blocking steps to decrease hydrophobic binding on polystyrene plates.

Lateral Flow and Rapid Immunoassays: Used as a sample/conjugate diluent to enhance specificity and maintain protein stability.

Bead-Based Multiplex Assays (e.g., Luminex): Provides consistent protein-friendly conditions for bead incubations and standard curves.

Immunohistochemistry/Immunofluorescence: Dilutes primary/secondary antibodies to reduce off-target binding in tissue and cell staining.

Protein Standards and Calibrators: Maintains analyte stability and linearity for standard curve preparation.

General Protein Stabilization: Temporarily stabilizes antigens, enzymes, and conjugates during assay setup and handling.

Assay Background Reduction: Lowers nonspecific adsorption and hydrophobic interactions in diverse plate-based binding assays.
