Source: Kerry M. Dooley and Michael G. Benton, Department of Chemical Engineering, Louisiana State University, Baton Rouge, LA The goal of this experiment is to determine the magnitude of maldistribution in typical packed bed reactors in both single phase and two-phase (gas-liquid) flow and evaluate the effects of this maldistribution on pressure drop. The concepts of residence time distribution and dispersion are introduced through the use of tracers, and these concepts are related to physical...

Improved Polydimethylsiloxane (PDMS) Double Casting via Silicone Oil Treatment for Densely Packed Microstructure Replication
0 Views •
2025
This protocol presents an improved demolding procedure for the Polydimethylsiloxane (PDMS) double casting technique by introducing silicone oil as a non-adhesive barrier between PDMS layers. Unlike plasma or chemical surface modification methods, this approach requires no specialized or costly equipment, making it a more accessible and cost-effective alternative.

A Lectin HPLC Method to Enrich Selectively-glycosylated Peptides from Complex Biological Samples

Lectin-conjugated POROS beads were employed for HPLC. Glycopeptide standards served as positive and negative controls. MARS-14 depleted, trypsin-digested human plasma was chromatographed and flow-through (FT) and bound fractions collected for ESI-LC-MS/MS analyses. Glycopeptides were enriched in the bound fraction as compared to FT.
FAQs
The chilled pack removes heat from the container and nearby materials, lowering their temperature during handling. This reduced temperature slows temperature-dependent processes such as enzymatic reactions, cellular metabolism, and sample degradation. By reducing the rate of these changes without necessarily freezing the material, the method helps maintain sample integrity during short periods outside controlled storage.
Limiting direct exposure to melting water helps keep the sample, reagent, or tissue separate from the cooling medium. This is important because the method depends on controlled cooling of the surrounding container rather than uncontrolled wetting. Preventing contact with meltwater also supports cleaner handling and reduces avoidable changes to the material during collection, transport, or preparation.
Researchers must monitor temperature closely because cooling is useful only when it remains compatible with the material being handled. Samples that are sensitive to ice formation may be damaged if they freeze. The ice pack therefore provides temporary cooling, but the user should prevent excessive cooling and avoid treating the method as a substitute for conditions designed for frozen storage.
A chilled pack is positioned to cool the surrounding container while the sample, reagent, or tissue is being handled. The material should remain protected from melting water, and its temperature should be monitored throughout the period of use. This workflow supports temporary cooling during collection, transport, dissection, or short-term experimental preparation without requiring specialized refrigeration.
The method is useful when biological material needs temporary cooling during collection, transport, dissection, or preparation, but specialized refrigeration is not available or necessary for that brief interval. Its main advantage is accessibility: a chilled pack can provide local cooling around a container. Researchers still need temperature control because the approach is intended for short-term handling rather than long-term preservation.
By slowing enzymatic reactions, cellular metabolism, and sample degradation, temporary cooling can help preserve the integrity of biological samples during handling. This is particularly relevant when material must be moved, collected, dissected, or prepared before an experiment. The outcome depends on maintaining suitable low temperatures without allowing ice formation in materials that are sensitive to freezing.
