Description
High-Transparency Gradient Gel for Reliable Blood Typing
Zetadex-50 Agglutination Grade from emp BIOTECH is a high-purity, cross-linked dextran-based density gradient gel designed for use with Gel Card Technology in immunohematology applications such as AHG, ABO-Rh, and Kell testing. Its controlled bead size distribution (20–50 µm dry) and excellent optical clarity ensure precise, reproducible results in blood typing and agglutination assays.
This specialty resin offers the selectivity and stability required for critical diagnostic workflows, while maintaining compatibility with common buffers and chemical agents. Its consistent performance and ease of handling make it a preferred choice for clinical and laboratory settings focused on blood group determination and antibody screening.
