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.

化学数据

不同实验动物依据体表面积的等效剂量转换表（数据来源于FDA指南）

例如，依据体表面积折算法，将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量，需要将20 mg/kg 乘以小鼠的K_m系数（3），再除以大鼠的K_m系数（6），得到化合物用于大鼠的等效剂量为10 mg/kg。
