I have ordered one of your research chemicals and it has seemed to have fallen out of suspension. What has happened here?
Even if stored properly, research chemicals are known for falling out of suspension. This can be easily fixed by running the chemical under hot water and shaking lightly.
Chemicals are not suspended unless they are water soluble. Shake rigorously and the precipitate will disperse back into the solution. Apply gentle heat if necessary.
Polyethylene glycol (PEG) 300.
The ideal container for peptide manipulation should be clean, chemically inert and optically clear & strong. We choose to use glass vials in lieu of polypropylene-based, plastic ones, in order to prevent any visibility problems when organic solvents are being used. We pride ourselves in only using high quality specialty glassware to inhibit the adsorption to surfaces which would grossly distort subsequent results.
We recommend storing out of direct sunlight, at room temperature and avoiding any fluctuations in humidity. By conservative estimates, this should prevent any degradation for several years.
We recommend storing in your refrigerator. By conservative estimates, this should prevent any degradation for a year or more prior to dissolution.
No. Dry-lyophilized peptides are stable at room temperature for several weeks. For long term storage, -20 degrees Celsius is preferred prior to dissolution.

- For structural studies >98% is recommended.
