Description
Gravity-Flow Antibody Purification with Base-Stable Protein A Resin
GraviPure Protein A Elevate from emp BIOTECH is a ready-to-use column packed with Zetarose Protein A Elevate, a highly cross-linked beaded agarose resin derivatized with NaOH-tolerant recombinant Protein A ligands. Designed for gravity-flow operation, the column enables simple, efficient purification of immunoglobulins via their selective affinity to Protein A — with no need for additional equipment.
This single-use format provides convenience for screening, rapid prototyping, or small-scale purification workflows. GraviPure columns are available in various capacities to match your experimental needs.
