Human Nectin-2 HEK293 Overexpression Lysate: Product Information

Product Description
This Human Nectin-2 overexpression lysate was created in HEK293 Cells and intented for use as a Western blot (WB) positive control. Purification of Nectin-2 protein (Cat: 10005-H02H) from the overexpression lysate was verified.
Expression Host
HEK293 Cells
Species
Human
Sequence Information
A DNA sequence encoding the extracellular domain (Met 1-Leu 360) of human CD112 (NP_002847.1) was fused with the Fc region of human IgG1 at the C-terminus.
Molecule Mass
The recombinant mature human CD112/Fc chimera is a disulfide-linked homodimeric protein. The reduced monomer consists of 567 amino acids and has a calculated molecular mass of 62.3 kDa. As a result of glycosylation, the rh CD112/Fc monomer migrates as an approximately 70-80 kDa protein in SDS-PAGE under reducing conditions.

Human Nectin-2 HEK293 Overexpression Lysate: Usage Guide

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

Nectin-2 Background Information

Cluster of Differentiation 112 (CD112), also known as poliovirus receptor related protein 2 (PVRL2 or PRR2), is a single-pass type I transmembrane glycoprotein belonging to the Immunoglobulin superfamily. CD112 protein also serves as an entry for certain mutant strains of herpes simplex virus and pseudorabies virus, and thus is involved in cell to cell spreading of these viruses. CD112 protein has been identified as the ligand for DNAM-1 (CD226), and the interaction of CD226/CD112 protein can induce NK cell- and CD8+ T cell-mediated cytotoxicity and cytokine secretion. CD112 has been regarded as a critical component in allergic reactions, and accordingly may function as a novel target for anti-allergic therapy.
Full Name
