BSA Blocking Buffer Solution in TBS with Azide is a pre-formulated, ready-to-use solution designed to block non-specific binding in protein assays. The solution contains bovine serum albumin (BSA) in Tris-buffered saline (TBS), with the addition of Azide to prevent microbial growth during storage. It is ideal for immunoassays such as ELISA, Western Blot, and immunohistochemistry, where blocking unoccupied binding sites is crucial to reduce background and improve assay sensitivity. The 200-milliliter bottle provides a convenient size for smaller-scale assays or for use in labs with limited storage capacity while maintaining high quality and performance.
