Product Description

This Human Kininogen 1 overexpression lysate was created in HEK293 Cells and intented for use as a Western blot (WB) positive control. Purification of Kininogen 1 protein from the overexpression lysate was verified.

Expression Host

HEK293 Cells

Species

Human

Sequence Information

A DNA sequence encoding the human KNG1 isoform 1 (NP_001095886.1) (Gln 19-Ser 644) was fused with a polyhistidine tag at the C-terminus, and a signal peptide at the N-terminus.

Molecule Mass

The recombinant human KNG1 consists of 637 amino acids and has a predicted molecular mass of 71.3 kDa. As a result of glycosylation, the apparent molecular mass of rhKNG1 is approximately 100-110 kDa in SDS-PAGE under reducing conditions.

Stability & Storage

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.

Preparation Method

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.

Lysis Buffer

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.

Recommend Usage

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.

Sample Buffer

1 X Sample Buffer (1 X modified RIPA buffer+1 X SDS loading buffer).

Synonyms

Human BDK Overexpression Lysate; Human BK Overexpression Lysate; Human KNG Overexpression Lysate

Application

Western Blot (WB). Optimal dilutions/concentrations should be determined by the end user.
