产品介绍

生物活性

Insulin (human) 是一种多肽激素,其调节血液中的糖(葡萄糖)水平并且由胰岛的β细胞产生。

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.

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)

小鼠大鼠豚鼠仓鼠
重量 (kg)0.020.151.80.40.0810
体表面积 (m2)0.0070.0250.150.050.020.5
Km系数36128520
动物 A (mg/kg) = 动物 B (mg/kg) × 动物 B的Km系数
动物 A的Km系数

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Km系数(3),再除以大鼠的Km系数(6),得到化合物用于大鼠的等效剂量为10 mg/kg。
