Insulin (human) [11061-68-0]

Biological Activity

Insulin (human) is a polypeptide hormone that regulates the level of sugar (glucose) in the blood and is produced by beta cells of islets.

*The product is unstable in the solution state, so it is recommended that you use it now and use it as soon as possible

This product solution cannot be autoclaved.
It is also soluble in 125mM NaHCO3. Alkaline storage solutions are not recommended as high pH increases deamidation and protein aggregation.
General recommendation:

1. Do not prepare concentrated insulin solution because of poor solubility and the formation of polymers.
2. Adjust acidic pH to promote solutization and minimize the effects of neutral ph-binding proteases. For added protection, acid protease inhibitors may be considered.
3. The solution was aseptically filtered using a 0.2 micron low protein binding filter. Avoid aeration and/or blistering during solubilization and filtration as this may lead to protein denaturation.
4. Store at 2-8°C for 8 hours.
5. Do not heat more than 30°C and do not freeze.
6. Recommended working concentration of insulin is 1-10 μg/mL.

As an alternative, insulin solutions can be formulated with phosphate buffers (PBS). The above products were dissolved in 1mg /mL PBS solution. Shake gently at room temperature for 1-2 hours. No whirlpool. The solution is ready for cleanup. Prior to evaluation, follow steps 3-6 for final processing.
