OctA-Probe Antibody (G-8) is a mouse monoclonal IgG2b kappa light chain antibody engineered to recognize OctA, also known as the FLAG tag or DYKDDDDK peptide, which is widely used in protein research. anti-OctA antibody (G-8) effectively detects FLAG-tagged fusion proteins in applications such as western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and enzyme-linked immunosorbent assay (ELISA), providing versatile tools for diverse experimental needs. The FLAG tag is an eight-amino-acid hydrophilic peptide incorporated into the N-terminus of target proteins expressed in bacterial, insect, and mammalian systems, facilitating their purification and visualization without significantly altering their native structure or function. The compact and hydrophilic nature of the FLAG tag ensures that fused proteins retain their biological activity and structural integrity, which is essential for accurate functional studies and interaction analyses. Additionally, the FLAG tag enhances solubility and simplifies the purification process, making it easier to isolate proteins of interest. OctA-Probe (G-8) monoclonal antibody is available in both non-conjugated and various conjugated forms, including agarose, horseradish peroxidase (HRP), phycoerythrin (PE), fluorescein isothiocyanate (FITC), and multiple Alexa Fluor® conjugates, allowing researchers to choose the appropriate format for their specific applications. The FLAG tag can be removed from the target protein post-purification using enterokinase, enabling further functional analyses without residual tags. OctA-Probe (G-8) antibody supports advanced studies in protein characterization, interaction mapping, and cellular localization by providing reliable detection and minimal disruption to protein structure.

Does the OctA-Probe Antibody (G-8): sc-166384 recognizes the 3x Flag: DYKDHDG-DYKDHDI-DYKDDDDK as it does for Flag: DYKDDDDK ? Unfortunately the actual amino acid sequence of the Octa (eight) is not disclose in Santa Cruz site. Thanks!

I am using the LiCor/Odyssey system. Which secondary antibody do you recommend using with OctA-Probe (G-8): sc-166384 monoclonal antibody?

Asked by: jenni
Thank you for your question We recommend using one of our our exclusive Mouse IgG Binding Proteins (m-IgGκ) conjugated to CFL 680 or CFL 790. They are suitable for use with Near-Infrared (NIR) detection systems, such as LI-COR/Odyssey and other comparable systems. A complete list of available binding proteins is available on our website here: https://www.scbt.com/scbt/browse/support-products-mouse-igg-binding-proteins/_/N-ecrety

Rated 4 out of 5 by from Ab for Flag-tagged proteinsgood antibody to use I used this antibody to detect a recombinant Flag-tagged protein in transfected Jurkat T cells. It works well for WB (1:500) but it also detects non-specific bands if using longer exposure.
