Western Blotting: Wash buffer for nitrocellulose/PVDF membranes to reduce nonspecific antibody binding.

ELISA: Plate wash buffer between incubation steps and diluent for antibodies/reagents to minimize background.

Immunohistochemistry/Immunofluorescence: Washing and mild permeabilization of tissues and cells during staining workflows.

Flow Cytrometry: Staining/wash buffer to limit cell aggregation and nonspecific interactions.

Immunoprecipitation/Bead-Based Assays: Wash buffer to remove nonspecific proteins from antibody- or ligand-coupled beads.

Protein/Nucleic Acid Blotting: Wash steps for Southern, Northern, and dot blots to lower background on membranes.

In Situ Hybridization: Detergent-assisted stringency washes to improve probe specificity.

Cell Culture Workflows: Gentle washing of adherent or suspension cells and removal of residual serum proteins.

Antibody/Antigen Dilution: Diluent for primary/secondary antibodies and antigens to stabilize and reduce nonspecific binding.

Bacterial Sample Processing: Washing of fixed bacterial cells (e.g., E. coli) prior to immunostaining or plate-based assays.
