EGFR Antibody (3i4) is a mouse monoclonal IgG1 antibody that detects amino acids 985-996 of EGFR of human origin in mouse, rat, and human samples through applications such as western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and immunohistochemistry. EGFR, or epidermal growth factor receptor, plays a crucial role in cell signaling pathways that regulate cell proliferation, survival, and differentiation. EGFR is primarily located on the cell membrane, where EGFR interacts with various ligands, including epidermal growth factor and transforming growth factor alpha, leading to receptor dimerization and activation of its intrinsic tyrosine kinase activity. EGFR′s location is crucial for initiating signaling cascades that influence critical cellular processes, such as organ development and tissue repair, by regulating epithelial cell proliferation during embryogenesis and promoting cellular migration and proliferation at wound sites. However, aberrant activation of EGFR is frequently associated with the progression of various cancers, making EGFR a significant target for therapeutic intervention. Anti-EGFR antibody (3i4) is particularly valuable for researchers studying the mechanisms of cancer biology and the potential for targeted therapies, as anti-EGFR antibody (3i4) can identify and quantify EGFR expression levels in different experimental contexts.

What blocking solution should I use with EGFR (3i4): sc-71032 monoclonal antibody for Western blot?

Asked by: Dr Ninau Qelp
Thank you for your question. We recommend blocking with Blotto (either TBS Blotto A: sc-2333 or TBS Blotto B: sc-2335). Our Western blot protocol can be found here: https://www.scbt.com/scbt/resources/protocols/western-immuno-blotting

Rated 1 out of 5 by from Bad antibodyWe received this sample antibody as a replacement for a previous antibody that has now been discontinued. We have validated our samples on multiple proteomic platforms to confirm the presence/absence of EGFR. Despite multiple attempts to optimize the antibody for Western Blot, our lab has not been successful validating our samples by Western Blot. I would not recommend this antibody for Western Blotting purposes.
