Product Description |
Recombinant Human KLKB1 Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Gly20-Ala638. |
Product Background |
Plasma kallikrein, also known as Fletcher factor or kallikrein B1 (KLKB1), is a serine endopeptidase, like its homologs tissue kallikrein and kallikrein-related peptidases (KLKs). Its physiological role is to catalyze the release of kinins and other vasoactive peptides. |

> 95% as determined by Bis-Tris PAGE;> 95% as determined by HPLC |
Endotoxin |
Less than 1EU per ug by the LAL method. |
Form |
Lyophilized |
Shipping |
Shipped at ambient temperature. |
Formulation |
Lyophilized from 0.22um filtered solution in 20mM NaAc,150mM NaCl (pH 5.0). Normally 8% trehalose is added as protectant before lyophilization. |
Reconstitution |
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in 20mM NaAc,150mM NaCl (pH 5.0). |
Stability And Storage |
Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles. |
