R-M-1742 V5 Epitope Tag Peptide Trifluoroacetate V5 Epitope Tag Peptide Trifluoroacetate is a Tag Peptide derived from a small Epitope on P and V proteins of monkey-virus paramyxovirus. price>
R-M-1750 T7 Tag Peptide,CAS: 245445-88-9 The T7 tag is an epitope tag composed of an 11-residue peptide encoded from the leader sequence of the T7 bacteriophage gene10. Epitope tags are useful for the labeling and detection of proteins using immunoblotting, immunoprecipitation, and immunostaining techniques. The T7 tag is commonly engineered onto the N- or C- terminus of a protein of interest so that the tagged protein can be analyzed and visualized using immunochemical methods. The T7 tag has been used extensively as a general epitope tag in many expression vectors including the pET system that is based on T7 RNA polymerase expression systems . price>
R-M-1752 S Tag Peptide S Tag Peptide is a 15 amino acid peptide derived from RNase A. price>
R-M-1890 X-press Tag Peptide  X-press Tag Peptide is a tag peptide used for protein purification. X-press Tag is also an N-terminal leader peptide; this N-terminal peptide contains a polyhistidine sequence, the Xpress epitope (part of bacteriophage T7 gene 10 protein) and an enterokinase cleavage site. Anti-Xpress antibodies recognize the Xpress epitope sequence found in this leader peptide. price>
