Lysing Matrix Y is used primarily for lysis of gram positive and gram negative bacteria, fungal tissue and spores, yeasts, molds, filamentous algaes and biofilms.
Each impact-resistant 2 mL tube contains 0.5 mm diameter Yttria-Stabilized Zirconium Oxide beads. Y2O3 + ZrO2 has high density and has extremely high hardness making this matrix ideal for cracking of very tough cell walls, while it's smooth surface minimizes shearing. Lysing Matrix Y tubes are found in the FastRNA Spin Kit for Microbes and the FastRNA Spin Kit for Yeast.
