Kallikrein 7/KLK7 Protein, Human, Recombinant (His Tag)

别称：hK7 Protein, Human; PRSS6 Protein, Human; SCCE Protein, Human

纯度:> 97 % as determined by SDS-PAGE

内毒素：< 1.0 EU per μg of the protein as determined by the LAL method

生物活性：Measured by its ability to cleave the fluorogenic peptide substrate, Mca-RPKPVE-Nval-WRK (Dnp) NH2, R&D Systems, Catalog # ES002. The specific activity is >150 pmoles/min/μg.

(Activation description: The proenzyme needs to be activated by Thermolysin for an activated form)

蛋白构建：A DNA sequence encoding the human KLK7 (NP_005037.1) extracellular domain (Met 1-Arg 253) was expressed, with a C-terminal polyhistidine tag.

NP No.：NP_005037.1

表达宿主：HEK293 Cells

种属：Human

预测 N 端：Glu 23

分子量：The secreted recombinant human KLK7 comprises 242 amino acids and has a predicted molecular mass of 26.7 kDa. As a result of glycosylation, the apparent molecular mass of rh KLK7 is approximately 30-33 kDa in SDS-PAGE under reducing conditions.

缓冲液：Lyophilized from sterile PBS, pH 7.4.

Please contact us for any concerns or special requirements.

Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.

Please refer to the specific buffer information in the hard copy of CoA.

运输方式：In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.

Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.

稳定性 & 储存条件：Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃

Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.

复溶：A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.
