Types of Protein Tags

Choose the right  format for your research

Fluorescent polypeptides consist of proteins or small peptides that are either naturally occurring or artificially generated, and they are often used in science to study proteins of interest within cells. Studies could focus on protein folding, location analysis, and protein function. Find below the most commonly used fluorescent polypeptides as protein tags:


keyboard_arrow_right   RFP (Red Fluorescent Protein): The original RFP was isolated from Discosoma, and named DsRed. Yields a red-orange colour when excited.
keyboard_arrow_right   mCherry: Member of the mFruits family of monomeric red fluorescent proteins. Derived from DsRed of Discosoma sea anemones.

These tags can be used in reporter assays, fluorescence microscopy, protein colocalization, macrophotography, immunoprecipitation  & more. 

Example of GFP-Tagged Protein Purification via Immunoprecipitation

An epitope tag is a short, genetically engineered amino acid sequence fused to a recombinant protein to facilitate its detection, purification, or imaging. By using commercially available antibodies that recognize the tag, scientists can easily study proteins that lack their own specific antibodies, using techniques like affinity chromatography for purification and immunofluorescence or flow cytometry for detection. Find below the most commonly used epitope tags:


keyboard_arrow_right   T7 (T7 RNA Polymerase): T7 RNA polymerase is a single-subunit enzyme (~99 kDa) from bacteriophage T7 that specifically recognizes and transcribes genes downstream of a T7 promoter sequence. Although not a typical small tag, T7 RNA polymerase can be fused to another protein for functional or localization purposes
keyboard_arrow_right   DDDDK: It’s a small peptide tag (~1 kDa) added to proteins for easy detection or purification using anti-FLAG antibodies or FLAG affinity resin.
keyboard_arrow_right   HA: HATag derives from a human influenza hemagglutinin protein, 98-106 amino acids in length. It's used in protein detection and purification, and as an epitope tag in expression vectors.
keyboard_arrow_right   Myc: Short peptide derived from the c-myc gene product. Often used in Affinity Chromatography, cellulite localization studies by immunofluorescence, Protein detection by Western blotting.
keyboard_arrow_right   V5: V5 Tag is a short peptide derived from the paramyxovirus (SV5) P/V proteinProtein detection and purification. It’s commonly fused to recombinant proteins for detection, purification, or localization. The tag is recognized by highly specific anti-V5 antibodies, making it useful in Western blotting, immunofluorescence, and immunoprecipitation.
Example of Protein Purification via Immunoprecipitation

Fusion tags are short peptide or protein sequences genetically attached to a target protein to improve its handling and study. They simplify purification, enable detection, enhance solubility, or direct cellular localization. These tags are widely used in recombinant protein expression to make protein production faster and more efficient. Find below the most commonly used affinity tags:

keyboard_arrow_right   His Tag: His tag (or 6×His tag) is a short sequence of six histidine residues. Often placed at a protein’s N- or C-terminus.
It binds strongly to nickel or cobalt ions, allowing affinity purification using Ni²⁺-NTA or Co²⁺ resins, and can also be detected with anti-His antibodies. Used for or easy protein purification and detection via metal affinity chromatography.
keyboard_arrow_right   TAP (Transporter associated with antigen processing):  Consists of two Immunoglobulin G (IgG) binding domains from the Staphylococcus aureus surface protein, Protein A, and a calmodulin-binding peptide (CBP). Often used for protein purification via protein A affinity chromatography.
Example of Protein Purification via Immunoprecipitation
Fusion tags are short peptide sequences or entire proteins genetically attached (fused) to a target protein to help with its expression, purification, detection, or functionality. Find below the most commonly used fusion tags:
keyboard_arrow_right   His Tag: His tag (or 6×His tag) is a short sequence of six histidine residues. Often placed at a protein’s N- or C-terminus.
It binds strongly to nickel or cobalt ions, allowing affinity purification using Ni²⁺-NTA or Co²⁺ resins, and can also be detected with anti-His antibodies. Because it’s small (~0.8 kDa) and rarely disrupts protein function, it’s one of the most popular fusion tags in protein expression systems.
keyboard_arrow_right   GST (Glutathione-S-transferase): Large tag consisting of 220 amino acids (roughly 26 kDa). Protein purification via pull-down assays.
keyboard_arrow_right   Trx (Thioredoxin): Thioredoxin is normally involved in the reduction of oxidised cysteine residues as well as the cleavage of disulfide bonds. Used as a solubilization tag. Assist protein folding, improve solubility of tagged protein.
keyboard_arrow_right   MBP (Maltose-binding protein): Thioredoxin is normally involved in the reduction of oxidised cysteine residues as well as the cleavage of disulfide bonds. Used as a solubilization tag. Assist protein folding, improve solubility of tagged protein.
