Use when the molecule must be functionally active, not just pure. ActiBioPure™ ? ActiBioPure™ — Aladdin's premier line for bioactive and recombinant products. Use when both high purity and preserved biological activity are required. Azide Free ? Azide-free — without sodium azide preservative. Use in conjugations, cell work, or assays where azide is toxic or inhibitory. High Performance ? High-performance grade with optimized purity and performance characteristics. Use for sensitive analyses where ordinary grades fall short. His Tag ? His tag grade — recombinant protein bearing a His tag for affinity purification/detection. Use to purify, immobilize, or detect the tagged protein. Fc tag ? Fc tag grade — recombinant protein bearing a Fc tag for affinity purification/detection. Use to purify, immobilize, or detect the tagged protein. The Fc tag aids dimerization and protein-A/G capture. ≥95%(SDS-PAGE)In Stock Item #: rp153757View ProductPricing & Pack Sizes
