## FAQ

### Can I use an insulin pen for laboratory research?

Not recommended. Pens dose in fixed increments and use cartridges not designed for repeated needle puncture and long-term cold storage.

### What insulin products do research labs use?

Most labs use standard vials of human insulin or insulin analogs from catalog suppliers, reconstituting to a known concentration like 100 U/mL.

### How long does reconstituted insulin last in the fridge?

Typically 28 days at 2-8°C if kept sealed. For longer storage, freeze aliquots at -20°C and avoid repeated freeze-thaw cycles.
