人脑促尿钠排泄肽(BNP) (Human)

产品描述:
Natriuretic Peptide Precursor B (BNP) acts as a cardiac hormone with a variety of biological actions including natriuresis, diuresis, vasorelaxation, and inhibition of renin and aldosterone secretion. It is thought to play a key role in cardiovascular homeostasis. Helps restore the body's salt and water balance. Improves heart function.

表达系统 :
Escherichia coli

溶解方法:
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at < -20°C. Further dilutions should be made in appropriate buffered solutions.

产品组成:
Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4.

存储条件:
This lyophilized preparation is stable at 2-8°C, but should be kept at -20°C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8°C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20°C to -70°C. Avoid repeated freeze/thaw cycles.

分子量:
Approximately 3.5 kDa, a single non-glycosylated polypeptide chain containing 32 amino acids.

内毒素:
Less than 1 EU/μg of BNP as determined by LAL method.
