Analysis Q 2503 : Target DNA - Cloning - Recombinant Protein - Experimental Procedures Q has included a sequence of letters, & numbers..... and a threat ? 6X-382-NTP0038-3u2 We know. So I thought I’d pop the numbers into a search, and I got this... https://rockland-inc.com/store/Antibodies-to-FLAG-and-Antibodies-to-6XHIS-Tags-600-401-382-O4L_13426.aspx It’s got the 6X, and also the 382..... So I read it...   Epitope tags are short peptide 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.  Rockland Immunochemicals produces anti-epitope tag antibodies against many common epitope tags including Myc, GST, GFP, 6X His, MBP, FLAG and HA. Rockland Immunochemicals also produces antibodies to other tags including FITC, Rhodamine (TRITC), DNP and biotin. I am no scientist, and I hope this is all benign, but some of the wordings made my neck hair stand on end...

Is this linking into Cabal experimentation ?
