Eppendorf LoBind microcentrifuge tubes are optimized for either proteomic or genomic (DNA/RNA) applications. Available in 0.5-, 1.5-, and 2.0-ml sizes, the tubes feature the Safe-Lock lid and contain no DNnase, RNase, human DNA, or PCR inhibitors. Constructed of polypropylene, they use no additives or coatings to achieve their low-binding characteristics: binding tests for the genomic tubes show <1;% DNA loss.
