Lab Desiccants and Drying Agents
Hygroscopic substances and drying agents for use in laboratory settings; drying agents are commonly used to keep other substances and samples dry, or to prevent moisture from forming on/in containers. Products include drying tubes, kits, etc.
Desiccants are typically chemicals or compounds that are hydroscopic (readily absorb moisture). Common desiccants include clays, silica gels, and calcium sulfate.
In the lab, desiccants are commonly used in desiccators and desiccator cabinets, with in-line air and gas drying columns, in absorption bulbs, U-tubes, glove boxes, sealed chambers, and wherever a dry environment is required. They are also used during transport, for storage, and maintaining materials and products ─ everything from clothing to electronics.
The moisture may come from a variety of sources:
- Water vapor in the air
- Moisture in packaging materials
- Moisture from permeation or leakage
Some desiccants contain an indicator or additive that produces a color change with moisture absorption. The indicator allows the user to see when the desiccant has absorbed its maximum amount of moisture and needs to be replaced or regenerated.
Some desiccants can be reused many times simply by heating them in an oven to allow moisture to evaporate. For indicating desiccants, one can also easily tell when the desiccant is again ready to use by the change back to the original color.
Desiccants may be available in a range of mesh or particle sizes. The Tyler Equivalent is a common type of mesh sizing and indicates the number of openings per linear inch of mesh. Common desiccant mesh sizes are 4, 8, and 10 to 12. Size 4 is typically used in gas phase applications; they are larger and less likely to break. Size 8 is smaller and can be more tightly packed.
Medchemexpress LLC RNA aptamer corn sodium | 5'-CGAGGAAGGAGGUCUGAGGAGGUCACUGC-3', sodium salt | 1 MG
RNA aptamer Corn sodium is a 28-nucleotide-long aptamer that is considerably shorter than Spinach and Spinach2. It exhibits bright red fluorescence when bound to DFHO, a soluble analog of the intrinsic fluorophore of red fluorescent protein. It can be used to visualize RNA expression or localization in live cells that have been soaked with chromophores.
- Substantially shorter than Spinach and Spinach2 (28-nt long).
- Exhibits bright red fluorescence upon binding DFHO.
- Can be used to visualize RNA expression or localization in live cells.
- The Corn-DFHO complex does not become appreciably cytotoxic when illuminated.
- Exhibits markedly increased photostability compared to other aptamer-chromophore complexes both in vitro and in vivo.
