Human NKG2D CHO Stable Overexpression Lysate: 製品の情報
This Human NKG2D overexpression lysate was created in CHO Stable Cells and intented for use as a Western blot (WB) positive control. Purification of NKG2D protein (Cat: 10575-H01S) from the overexpression lysate was verified.
CHO Stable Cells
A DNA sequence encoding the human NKG2D (NP_031386.2) (Phe78-Val216) was expressed with the Fc region of human IgG1 at the N-terminus.
The recombinant human NKG2D/Fc comprises 418 amino acids and has a predicted molecular mass of 46.5 kDa. The apparent molecular mass of the protein is approximately 50-64 and 37 kDa in SDS-PAGE under reducing conditions.
Human NKG2D CHO Stable 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.

NKG2D, also known as CD314, is an immune receptor which consists of two disulphide-linked type II transmembrane proteins with short intracellular proteins uncapable to transduce signals. In order to transduce signals, NKG2D needs adaptor proteins and it uses two adaptor proteins, DAP1 and DAP12. These two adaptor proteins associate as homodimers to NKG2D- therefore the entire receptor complex appears as a hexamer. NKG2D can send co-stimulatory signals to activate CD8 T cells. NKG2D also plays an important role in viral control. Cellular stress can induce ligands for NKG2D which results in the cell susceptible to NK cell-mediated lysis.
