Application Notes
Each vial of cell lysate contains 100ug of total protein which should be sufficient for 20-50 reactions. Depending on over-expression level, antibody affinity and detection system, some lysates can go as low as 0.1 ug per load. We recommend starting with 5ug of cell lysate. Add an equal amount of cell lysate and 2X SDS Sample buffer and boil the SDS samples for 10 minutes before loading.
TMW
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Background: NKp46/NCR1
NKp46 plays a critical role in the NK-cell lysis of allogenic, autologous, and xenogeneic cells (3). Activation of NKp46 signaling is mediated via its association with immunoreceptor tyrosine-based activation motif (ITAM) bearing molecules CD3zeta and FcRgamma (3). Upon receptor-engagement NK-cell cytotoxic activity and cytokine release occurs (3). This NKp46 signaling can be blocked with anti-NKp46 monoclonal antibody mediated cross-linking which causes calcium release and interferon-gamma (IFN-gamma) and tumor necrosis factor-alpha (TNF-alpha) secretion (3). NKp46 recognizes multiple ligands presented on tumor cells or pathogens and infected cells including influenza virus hemagglutinin and the parainfluenza virus hemagglutinin neuraminidase (2). Additional ligands for the NKp46 receptor include heparan sulfate (HS) glycosaminoglycans (GAGs), hemagglutinin of human vaccina virus, and vimentin expressed on cells infected with Mycobacterium tuberculosis (3).
NKp46 and its NCR counterparts have shown to be successful targets for cancer immunotherapy. More specifically, human and mouse NKp46 has shown promise in virotherapy due to its ability to stimulate NK cell activation by binding to reovirus sigma1 protein in a sialic acid-dependent manner (3). Another approach for NKp46 in cancer immunotherapy is through the use of NCR based chimeric antigen receptors (CARs). In this therapy, NCR1 supplied human T cells with anti-tumor properties via cytokine secretion, upregulation of activation markers, improved expansion, and cytotoxicity in both mouse and in vitro models (3).

HEK293T cells in 10-cm dishes were transiently transfected with a non-lipid polymer transfection reagent specially designed and manufactured for large volume DNA transfection. Transfected cells were cultured for 48hrs before collection. The cells were lysed in modified RIPA buffer (25mM Tris-HCl pH7.6, 150mM NaCl, 1% NP-40, 1mM EDTA, 1xProteinase inhibitor cocktail mix, 1mM PMSF and 1mM Na3VO4, and then centrifuged to clarify the lysate. Protein concentration was measured by BCA protein assay kit.
