BioVision's Albumin Depletion Kit provides easy and user-friendly spin columns for depletion/removal of abundant albumin protein from samples thus enhancing the sample analysis. The kit is based on the interaction of Cibacron Blue 3G-A (immobilized on beads) with albumin. Each spin column can bind ~2-3 mg of albumin and processes sample in less than one hour. After albumin depletion, samples can be used for subsequent ELISA, immunoassays and other downstream analyses such as gel electrophoresis and functional assays. These columns can also be used for purification and enrichment of a variety of Cibacron Blue dye-binding proteins.
