Formulation
Common Applications
Storage

PBS Assay Diluent is a ready-to-use phosphate-buffered saline with 1% BSA and 0.05% polysorbate 20 (Tween-20). The 1 L fill supports laboratory and pilot-scale use.

It is commonly used to dilute samples, standards, and detection antibodies in ELISAs and other immunoassays, including host cell protein (HCP) and residual Protein A assays for biologics. BSA and surfactant reduce nonspecific binding and matrix effects.
