Yes. PAXgene Tissue STABILIZER can be used to fill the first position of a tissue processor. See the appendices of the PAXgene Tissue Container Product Circular and PAXgene Tissue FIX Container (50 ml) Product Circular for processing protocols with integrated PAXgene Tissue STABILIZER. When the STABILIZER is included as the first step of a protocol, tissue can be transferred from PAXgene Tissue FIX directly into the first processing position.
