免疫原
Synthetic peptide corresponding to the DYKDDDDK epitope tag peptide DYKDDDDK(Asp-Tyr-Lys-Asp-Asp-Asp-Asp-Lys) conjugated to KLH using maleimide. Remarks: Residues of Glycine and Cysteine were added to the termini to facilitatecoupling.
This antibody is optimally suited for monitoring the expression of DYKDDDDK tagged fusionproteins. As such, this antibody can be used to identify fusion proteins containing theDYKDDDDK epitope. The antibody recognizes the epitope tag fused to either the amino- orcarboxy- termini of targeted proteins. The epitope tag peptide sequence was first derivedfrom the 11-amino-acid leader peptide of the gene-10 product from bacteriophage T7. DYKDDDDK is the most commonly used hydrophilic octapeptide tag.

Sequences that are easily recognized by tag-specific antibodies. Due to their small size, epitope tags do not affect the tagged protein's biochemical properties. Most often sequences encoding the epitope tag are included with target DNA at the time of cloning to produce fusion proteins containing the epitope tag sequence. This allows anti-epitope tag antibodies to serve as universal detection reagents for any tag containing protein produced by recombinant means. This means that anti-epitope tag antibodies are a useful alternative to generating specific antibodies to identify, immunoprecipitate or immunoaffinity purify a recombinant protein. The anti-epitope tag antibody is usually functional in a variety of antibody-dependent experimental procedures. Expression vectors producing epitope tag fusion proteins are available for a variety of host expression systems including bacteria, yeast, insect and mammalian cells.
