Human Kallikrein 11 HEK293 Overexpression Lysate: 製品の情報

製品の説明
This Human Kallikrein 11 overexpression lysate was created in HEK293 Cells and intented for use as a Western blot (WB) positive control. Purification of Kallikrein 11 protein (Cat: 10767-H08H) from the overexpression lysate was verified.

タンパク質構築情報
A DNA sequence encoding the human KLK11 isoform 1 (NP_006844.1) (Met 1-Asn 250) with a C-terminal polyhistidine tag was expressed.
分子量
The secreted recombinant human KLKL11 comprises 243 amino acids with a predicted molecular mass of 27 kDa. As a result of glycosylation, rhKLK11 migrates as an approximately 40 kDa band in SDS-PAGE under reducing conditions.

Human Kallikrein 11 HEK293 Overexpression Lysate: 用法

調製方法
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.
溶解バッファー
Modified RIPA Lysis Buffer: 50 mM Tris-HCl pH 7.4, 150 mM NaCl, 1mM EDTA, 1% Triton X-100, 0.1% SDS, 1% Sodium deoxycholate, 1mM PMSF.
おすすめの用法
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.
バッファー
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.
アプリケーション
Western Blot (WB)
Optimal dilutions/concentrations should be determined by the end user.

Kallikrein 11 背景情報

kallikrein-related peptidase 11 (KLK11), also known as hippostasin, trypsin-like serine protease and PRSS2, is a member of human tissue kallikrein family. It is a subgroup of serine proteases with diverse physiological functions, which is implicated in carcinogenesis and some with potential that serving as novel biomarkers for ovarian and prostate cancer and other diseases. The KLK11 gene is one of the fifteen kallikrein subfamily members located in a cluster on chromosome 19. Two alternatively spliced forms exist, resulting in 25 (isoform 1) and 282 (isoform 2) amino acid sequences. Isoform 2 is identical to isoform 1, except for an inserted 32 amino acid segment. Isoform 1 is predominantly expressed in brain whereas isoform 2 is preferentially expressed in prostate.
