Human Kallikrein 1 HEK293 Overexpression Lysate: 製品の情報
This Human Kallikrein 1 overexpression lysate was created in HEK293 Cells and intented for use as a Western blot (WB) positive control. Purification of Kallikrein 1 protein (Cat: 10407-H08H) from the overexpression lysate was verified.
A DNA sequence encoding the human KLK1 (NP_002248.1) precursor (Met 1-Ser 262) was expressed with a polyhistidine tag at the C-terminus.
The secreted recombinant human KLK1 is a monomeric protein after cleavage of the signal peptide. It consists of 251 amino acids and predictes a molecular mass of 28 kDa. In SDS-PAGE under reducing conditions, it migrates with the apparent molecular mass of 50 kDa due to glycosylation.
Human Kallikrein 1 HEK293 Overexpression Lysate: 用法
Cell lysate was prepared by homogenization of the over-expressed cells in ice-cold modified RIPA Lysis Buffer with cocktail of protease inhibitors (Sigma). Cell debris was removed by centrifugation. Protein concentration was determined by Bradford assay (Bio-Rad protein assay, Microplate Standard assay). The cell lysate was boiled for 5 min in 1 x SDS loading buffer (50 mM Tris-HCl pH 6.8, 12.5% glycerol, 1% sodium dodecylsulfate, 0.01% bromophenol blue) containing 5% b-mercaptoethanol, and lyophilized.
1. Centrifuge the tube for a few seconds and ensure the pellet at the bottom of the tube.
2. Re-dissolve the pellet using 200μL pure water and boil for 2-5 min.
1 X Sample Buffer (1 X modified RIPA buffer+1 X SDS loading buffer).
安定性 & 保存条件
Store at 4℃ for up to twelve months from date of receipt. After re-dissolution, aliquot and store at -80℃ for up to twelve months. Avoid repeated freeze-thaw cycles.
Western Blot (WB) Optimal dilutions/concentrations should be determined by the end user.

Kallikrein 1 背景情報
Human tissue kallikrein (KLK1) is a serine protease, component of the KKS that has been demonstrated to exert pleiotropic beneficial effects in protection from tissue injury through its antiinflammatory, antiapoptotic, antifibrotic and antioxidative actions.Polymorphism of the human tissue kallikrein 1 (KLK1) A1789G gene is associated with susceptibility to hypertension.
