ELISA Sample/Standard Diluent: Minimizes matrix effects and nonspecific binding in plate-based immunoassays.

Antibody Diluent: Optimizes primary and secondary antibody performance while reducing background.

HRP/AP Conjugate Diluent: Stabilizes enzyme-conjugated antibodies for consistent signal.

Blocking/Soak Buffer: Blocks nonspecific binding sites on plates and membranes.

Wash Buffer Substitute: Provides gentle surfactant-mediated washing to lower background in immunoassays.

Calibration/Control Preparation: Dilutes standards and controls to create accurate curves.

Bead-Based Immunoassays (e.g., Luminex): Dilutes samples and reagents while preserving bead–analyte interactions.

Lateral Flow Assays: Serves as a running/sample diluent to enhance flow and specificity.

Protein Stabilization: Short-term stabilization of proteins and peptides during handling.

Flow Cytometry Staining Diluent: Dilutes antibodies for cell surface staining while reducing nonspecific binding.
