Tag Peptides

3X FLAG peptides are FLAG-tagged peptides containing three repeats of the Asp-Tyr-Lys-Xaa-Xaa-Asp motif. 3X FLAG peptide can be used for protein separation and purification, and competitive elution with target proteins.

FLAG peptide is a multifunctional fusion tag for the purification of recombinant proteins. FLAG peptide maintances the natural folding of its fusing proteins. FLAG peptide can be removed by enterokinase, and eluted under non-denaturing conditions.

HA Peptide (HA tag) is a nine amino acids peptide derived from the human influenza hemagglutinin (HA). HA Peptide is extensively used to isolate, purify, detect, and track the protein of interest in cell biology and biochemistry.

3X FLAG peptide TFA is a FLAG-tagged peptide containing three repeats of the Asp-Tyr-Lys-Xaa-Xaa-Asp motif. 3X FLAG peptide TFA can be used for protein separation and purification, and competitive elution with target proteins.

Hexa-His (6X His Tag) is a commonly used affinity tag made up of six histidine residues. HEXA-HIS can bind to affinity chromatography media containing transition metal ions like nickel (Ni²⁺) or cobalt (Co²⁺), making it useful for protein purification.

3X HA Tag is a biological active peptide. (This tag peptide may be used to detect proteins and peptides, and to facilitate functional analysis of proteins of interest.)

HA Peptide (TFA) is a nine amino acids peptide derived from the human influenza hemagglutinin (HA). HA Peptide (TFA) is extensively used to isolate, purify, detect, and track the protein of interest in cell biology and biochemistry.

c-Myc Peptide (TFA) is a synthetic peptide corresponding to the C-terminal amino acids (410-419) of human c-myc protein, and participates in regulation of growth-related gene transcription.

V5 Epitope Tag Peptide TFA is a tag peptide derived from a small epitope present on the P and V proteins of the paramyxovirus of simian virus 5. V5 Epitope Tag Peptide TFA can be used for protein separation and purification, and competitive elution with target proteins.

FLAG peptide TFA is the TFA salt form of FLAG peptide (HY-P0223). FLAG peptide TFA is a multifunctional fusion tag for the purification of recombinant proteins. FLAG peptide TFA maintances the natural folding of its fusing proteins. FLAG peptide TFA can be removed by enterokinase, and eluted under non-denaturing conditions.

3x DYKDDDDK Tag is a useful tool for investigating the function and localization of proteins whose antibodies (Abs) are not available. Often it is also used in a 3X FLAG format (3x DYKDDDDK Tag) for purifying difficult proteins that accumulate in low abundance .

ALFA-tag is a small and stable α-helical structure composed of 15 amino acids. ALFA-tag is highly hydrophilic and can be placed at the N-terminus, C-terminus, or between two independently folded domains of the target protein without affecting the function of the protein. ALFA-tag is widely used as an epitope tag and is used for the detection and manipulation of proteins in living cells.

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

Azido-PEG3-DYKDDDDK (azide-PEG3-FLAG) TFA is a multifunctional fusion tag for the purification of recombinant proteins. Azido-PEG3-DYKDDDDK TFA 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.

S Tag Peptide is a 15 amino acid peptide derived from RNase A.

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

SmBiT Tag is an 11-amino-acid short peptide with extremely low natural affinity for LgBiT, with a K_d value of approximately 190 μM. It serves as a core component of the NanoLuc Binary Technology (NanoBiT) system. NanoBiT is a bioluminescent reporter system based on protein fragment complementation technology, which is used to monitor dynamic protein-protein interactions in live cells and in vitro.

DYKDDDDK peptide (FLAG) is a useful tool for investigating the function and localization of proteins whose antibodies (Abs) are not available. Often it is also used in a 3X FLAG format (3x DYKDDDDK Tag TFA) for purifying difficult proteins that accumulate in low abundance .

VSV-G tag Peptide is a 11 amino acid peptide derived from the Vesicular Stomatitis viral glycoprotein. VSV-G tag Peptide can integrate into the cell membranes of animal cells, induce cell fusion, and significantly enhance the efficiency of DNA transfection into animal cells. VSV-G tag Peptide can be used for research on drug delivery.

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.
