Highly specific and rigorously validated in-house, DYKDDDDK Tag Antibody (Binds to same epitope as Sigma-Aldrich Anti-FLAG M2 antibody) (CST #2368) is ready to ship. Product Usage Information Western Blotting: 1:1000 Immunoprecipitation: 1:50 Flow Cytometry (Fixed/Permeabilized): 1:200 Storage Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at -20°C. Do not aliquot the antibody. Protocol Available protocols: Western Blotting, Immunoprecipitation, Flow Cytometry (Fixed/Permeabilized) Specificity / Sensitivity DYKDDDDK Tag Antibody (Binds to same epitope as Sigma-Aldrich Anti-FLAG M2 antibody) detects exogenously expressed DYKDDDDK proteins in cells. This antibody recognizes the DYKDDDDK peptide (the same epitope recognized by Sigma-Aldrich Anti-FLAG M2 antibody) fused to either the amino- or carboxy-terminus of targeted proteins. The binding specificity of this antibody is NOT dependent on the presence of divalent metal cations. Species Reactivity: All Species Expected Source / Purification Polyclonal antibodies are produced by immunizing animals with a synthetic DYKDDDDK peptide. Antibodies are purified by protein A and peptide affinity chromatography. Background Epitope tags are useful for the labeling and detection of proteins using immunoblotting, immunoprecipitation, and immunostaining techniques. Because of their small size, they are unlikely to affect the tagged protein's biochemical properties. The DYKDDDDK peptide has been used extensively as a general epitope tag in expression vectors. This peptide can be expressed and detected with the protein of interest as an amino-terminal or carboxy-terminal fusion (1). Specification REACTIVITY: All SENSITIVITY: Transfected Only SOURCE: Rabbit
