Tag Antibodies

What are Epitope Tags

Epitope tags are short peptide sequences that are added to proteins of interest. The addition of these tags allows for the detection and purification of the tagged protein using specific antibodies (anti-tag antibodies). These tags are generally small and do not affect the function of the protein, making them useful tools in many research applications.

Uses of Epitope Tags in Cell Biology and Immunology

Epitope tags are used in cell biology and immunology. For example, by adding a tag to a protein, it can be tracked in living cells and even in animals. The most common tags used in this context are GFP, RFP and YFP. These tags are fluorescent proteins and allow the visualization of the location and dynamics of the tagged protein in living cells.

Uses of Epitope Tags in Molecular Biology and Biochemistry

In molecular biology and biochemistry, epitope tags are commonly used to purify and detect specific proteins. For example, the most common tags are His-tag and Flag-tag, which are small peptides added to the N- or C-terminus of the protein. These tags can be used to purify the protein using anti-tag antibodies coupled to beads.
