Widely used as a non-ionic surfactant, it is commonly employed in biological research and industrial applications. In immunoassays such as ELISA, it helps reduce background noise by minimizing non-specific binding on microplate surfaces. Also used in Western blotting to reduce non-specific antibody binding during membrane washing. Frequently added to washing buffers to enhance the removal of unbound reagents without disrupting specific antigen-antibody interactions. Also used in cell lysis buffers to solubilize membrane proteins while maintaining protein functionality. In pharmaceutical formulations, it improves the stability and solubility of active ingredients. Commonly found in diagnostic kits, it ensures consistent and reliable assay performance. Its low toxicity and high biocompatibility make it suitable for use in cosmetics and personal care products as an emulsifier and solubilizing agent.
