Human Kallikrein 2/KLK2 Protein (active form)

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Human Kallikrein 2/KLK2 Protein (active form) is expressed from HEK293 with His tag at the C-terminus.
It contains Ile25-Pro261 [Accession | P20151-1].

分子量大小(Molecular Weight)

The protein has a predicted MW of 27.4 kDa. Due to glycosylation, the protein migrates to 27-35 kDa based on Bis-Tris PAGE result.

纯度(Purity)

> 90% as determined by Bis-Tris PAGE

内毒素(Endotoxin)

Less than 0.1 EU per μg by the LAL method.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in 20mM Tris, 150mM NaCl, 8% trehalose, 0.05% Brij-35, 5mM Benzamidine (pH 8.0).

重构方法(Reconstitution)

Dissolve the lyophilized protein in distilled water. Please refer to the Certificate of Analysis for detailed instructions.

存储(Storage)

-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3 months after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
