Human exposure to carcinogens occurs via a plethora of environmental sources, with 70–90% of cancers caused by extrinsic factors. Aberrant phenotypes induced by such carcinogenic agents may provide universal biomarkers for cancer causation. Both current in vitro genotoxicity tests and the animal-testing paradigm in human cancer risk assessment fail to accurately represent and predict whether

To demonstrate operation of fizzy extraction, a test sample was loaded into a 20 mL vial (extraction chamber; Figure 1A,B). During the extraction procedure, carbon dioxide was pumped to the headspace of the extraction chamber for 60 s in order to remove the residues of ambient air and volatile contaminants ( Figure 2 and Movie S1 ).

The DNA concentration of each product was measured by NanoDrop (2000c; Thermo Fisher Scientific). The absolute copy number of each sample was calculated according to the following formula: C = A/B × 6.02 × 10 14 , where A is the concentration obtained by OD260 analysis (ng/μl), B is the molecular weight of the synthesized DNA (Daltons), and

It’s easy to take for granted the containers you entrust with your valuable samples and solutions. But not all bottles are created equal. Nalgene is the #1 choice, with more than 3,000,000 safely at work in laboratories around the world.

Accucore C30 offers high shape selectivity for hydrophobic, long chain, structurally related isomers, for example carotenoids and steroids. This is a different form of shape selectivity from that measured in the SS phase characterisation test. It is also an excellent alternative to normal-phase columns for lipid analysis. The

The versatile culture tubes can hold, mix, or heat contents, making the glassware a laboratory essential. Transparent manufacturing allow researchers to constantly monitor contents. Shaped for easier retrieval and minimal sample loss, the containers require smaller working quantities.
