Tag Peptides

Rhodopsin Epitope Tag is a 9-amino acid peptide localized within the C-terminal region of bovine rhodopsin . Rhodopsin Epitope Tag is widely used as an epitope tag and can be recognized by a number of anti-rhodopsin antibodies.

Hexa-His TFA is a peptide consisting of 6 His residues, used as a metal binding site for the recombinant protein.

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.

Cys-V5 Peptide, a tag peptide, is the V5 Peptide with an N-terminal cysteine. Cys-V5 Peptide can be used to label proteins

T7 Tag Peptide TFA is a protein tag consisting of 11 residues from the N-terminus of the T7 bacteriophage capsid protein gp10. T7 Tag Peptide TFA can be fused to the N-terminus or C-terminus of proteins such as enhanced green fluorescent protein (EGFP). T7 Tag Peptide TFA can be used in various immunoassays and affinity purification.

SsrA tag is an 11-aa peptide added to the C-terminus of proteins stalled during translation, targeting them for degradation by ClpXP and ClpAP.

WSHPQFEK has a high affinity for Streptavidin and can be used as a tag peptide for recombinant protein separation, purification, and detection.

2x HA tag peptide is a tag peptide (YPYDVPDYAYPYDVPDYA) with a hemagglutinin HA tag. 2x HA tag peptide is often used to be fused to the 5' end of the target protein to label the protein.

Azido-PEG3-DYKDDDDK (azide-PEG3-FLAG) is a multifunctional fusion tag for the purification of recombinant proteins. Azido-PEG3-DYKDDDDK is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.

His11 TFA is consists of a contiguous series of amino acid residues. His11 TFA can be used as a tag peptide.

FLAG-Cys is a Flag peptide with a Cys residue. FLAG-Cys has immunogenicity.

Atrial Natriuretic Peptide (7-28), human, canine is a peptide fragment of atrial natriuretic peptide, can be used as a peptide tag.

Osteocalcin (7-19) (human) is a peptide fragment of Osteocalcin, can be used as a peptide tag.

YEQLRNSRA is a MycC Peptide. MycC Peptide is encoded by c-myc proto-oncogene, the c-myc oncogene has been implicated in malignant progression in a variety of human tumors. MycC Peptide regulates fundamental cellular processes like growth control, metabolism, proliferation, differentiation, and apoptosis.
