Validate your liquid transfers whenever dimethyl sulfoxide solvent is used

Because DMSO has very different physical properties than water it behaves differently when handled by air-displacement pipettors or acoustic droplet ejectors, creating the need for a solvent-specific volume verification method such as that provided by the new DMSO Range E Solution for the MVS. DMSO-based Sample Solutions Will Help You: - Ensure concentrations of compounds in assay plates by measuring nL volumes of 100% DMSO - Measure performance of acoustic dispensing systems and other low-volume liquid dispensers - Standardize nL volume delivery across liquid handler types with DMSO- and aqueous-based solutions

Dimethyl sulfoxide (DMSO) has become one of the most important solvents used for high-throughput screening (HTS) and compound management applications due to its ability to readily dissolve a wide range of compounds. DMSO has very different physical properties than water it behaves differently when handled by air-displacement pipettors, automated liquid handlers or acoustic droplet ejectors, creating the need for a solvent-specific volume verification method such as that provided by the DMSO QualAssure for the MVS. The MVS DMSO QualAssure solutions can measure performance over a wide volume range of 0.0001 to 9.999 µL.

A 100% DMSO QualAsssure solution has been developed for use with the MVS. DMSO QualAssure is capable of measuring volumes down to 10 nL. As with all MVS QualAssure solutions, results are traceable to international standards.

Research has shown that the volumes dispensed during drug screening programs can have a significant effect on the results obtained by assay screens.1 Any error made during these deliveries affects the concentration of the drug candidate and can lead to misleading data about compound activity being generated.

DMSO has very different physical properties than water, the liquid most commonly used for calibration and performance verification, therefore,  it behaves differently when handled by air-displacement pipettors or acoustic droplet ejectors, creating the need for a solvent-specific volume verification methods, which is provided by DMSO E for the MVS.

Artel has developed and characterized a 100% DMSO-based dye solution for use with the Artel MVS® Multichannel Verification System. This article discusses the challenges and performance capabilities of a DMSO-based dual-dye solution developed for the MVS. The DMSO-based solution is capable of measuring dispensed volumes as small as 10 nL. Data presented suggests that if two successive liquid transfers are inaccurate, critical reagent concentrations could be affected by as much as 50%.2

This data demonstrates that 100% DMSO E adds a significant capability to the MVS for measuring liquid handling instrument performance. This capability answers the need for those scientists working in the drug discovery arena for a fast and reliable method to verify that their liquid handling instruments are accurately and precisely dispensing DMSO-based solutions.

DMSO-based QualAssure solutions will help you:

  • Ensure concentrations of compounds in assay plates by measuring nL volumes of 100% DMSO
  • Measure performance of acoustic dispensing systems and other low-volume liquid dispensers
  • Standardize nL volume delivery across liquid handler types with DMSO- and aqueous-based solutions
