Background: EGFR is a receptor tyrosine kinase binding ligands of the EGF family and activating several signaling cascades to convert extracellular cues into appropriate cellular responses. It activates at least 4 major downstream signaling cascades including the RAS-RAF-MEK-ERK, PI3 kinase-AKT, PLC gamma-PKC and STATs modules. Defects in EGFR are associated with lung cancer (LNCR).
Immunogen: A synthetic peptide from the internal region of EGFR which includes the mutation of L858R, human origin.
Constituents: PBS (without Mg2+ and Ca2+), pH 7.4, 150 mM NaCl, 50% glycerol
Species Reactivity: Recognizes EGFR(L858R), but not wild type EGFR from vertebrates.
Storage Conditions: Store at -20°C. Avoid repeated freezing and thawing.
Western blot:
Immunofluorescence:
Immunofluorescence of cells expressing EGFR proteins with anti EGFR(L858R) antibody. HEK293T cells were transfected with pCDNA3-GFP-EGFR (WT) plasmid (left column) or pCDNA3-GFP-EGFR L858R) plasmid (right column), then fixed and stained with anti- EGFR(L858R) monoclonal antibody (Cat. # TD-26082). Immunohistochemistry:
Immunohistochemical analysis of paraf\fin-embedded human NSCLC tissue with anti-EGFR(L858R) monoclonal antibody (Cat. #TD-26082). Tissue samples were fixed with formaldehyde and blocked with 1% serum for 15 min at 37 °C. Antigen retrieval was by heat mediation in citrate buffer (pH6). Samples were then incubated with primary antibody (1:400) overnight at 4°C. A HRP-conjugated Goat anti-mouse IgG (dilution 1:100) was used as secondary antibody.
