Disposable plasticware such as test tubes, pipette tips, and multiwell assay or culture plates are used routinely in most biological research laboratories. Manufacturing of plastics requires the inclusion of numerous chemicals to enhance stability, durability, and performance. Some lubricating (slip) agents, exemplified by oleamide, also occur endogenously in humans and are biologically active, and cationic biocides are included to prevent bacterial colonization of the plastic surface. We… 

On the disruption of biochemical and biological assays by chemicals leaching from disposable laboratory plasticware.

The nature and sources of leachates are discussed and several examples of compromised bioassay data that speak to the probable widespread nature of this largely unrecognised source of error are reviewed.

Abl1 inhibitory contaminants leach from plastic tubes

Results indicated that the tube extracts had no significant cytotoxicity but could inhibit the activity of Abl1, suggesting that these bioactive leachates from plastic tubes might be a specific inhibitor of tyrosine kinase.

Labware Additives Identified to Be Selective Monoamine Oxidase-B Inhibitors

The identification of biologically active substances released from a commonly used plastic microplate were identified by gas chromatography–mass spectroscopy as dodecan-1-ol, dodecyl 3-(3-dodecoxy-3-oxopropyl)sulfanylpropanoate, and dodecanoic acid, and they were found to be selective monoamine oxidase-B inhibitors.

Extraction, Identification, and Functional Characterization of a Bioactive Substance From Automated Compound-Handling Plastic Tips

Results demonstrate that solvent-extractable contaminants from some plastic labware used in the contemporary pharmaceutical research and development (R&D) environment can be introduced into physical and biological assays during routine compound management liquid-handling processes.

The influence of UV absorbing substances released from plastic containers (leachables) on photometric analyses

Plastic consumables, which are routinely used in the laboratory, can release substances which may subsequently compromise experiments, so called leachables. This was demonstrated in a number of

Characterization of a cyclic olefin polymer microcentrifuge tube.

The results show COP microcentrifuge tubes perform as well as tubes made of PP, with reduced levels of compounds capable of leaching into solvents typically used in the laboratory.

Comparison of Eppendorf Tubes ® 5.0 mL to conical 15 mL tubes with a focus on releasable UV-absorbing substances (leachables)

It can be shown that a significant amount of leachables is released from the different 15 mL vessels, and for Eppendorf Tubes (and a glass control vessel) these extinctions are so low that photometric detection methods are not compromised.

Laboratory Plasticware Induces Expression of a Bacterial Virulence Factor

Millions of tons small plastic pieces (microplastic) find their way into the environment every year. They pose digestive and toxicity problems to various life forms in soil, freshwater, and seawater.

Extractables and Leachables in Microcentrifuge Tubes – Extensive HPLC / GC / MS Analysis

Substances leaching out of plastic consumables (leachables) are still underestimated in a majority of life science applications. Increasing scientific evidence shows that this heterogeneous and



Migration studies on fatty acid amide slip additives from plastics into food simulants.

Specific migration studies, using food simulants, have been conducted on a range of polymers which are used in food packaging and contain commonly used fatty acid amide slip additives. Migration

Contamination of bottled waters with antimony leaching from polyethylene terephthalate (PET) increases upon storage.

Elevated concentrations of Sb in bottled waters are due mainly to the Sb2O3 used as the catalyst in the manufacture of polyethylene terephthalate (PET(E).

Oleamide: a fatty acid amide signaling molecule in the cardiovascular system?

A physiological role for oleamide in the heart and circulation has yet to be demonstrated, as has production by cells of the cardiovascular system, but this molecule has a range of actions that could give it considerable modulatory power.
