What is ha tag sequence?

A ha tag sequence is a short amino acid sequence that is added to a protein of interest to facilitate its detection and purification in various biochemical and biophysical experiments. The ha tag sequence consists of the following amino acids: Tyr-Pro-Asn-Pro-Ala-Tyr-Tyr-Asn.

The ha tag is often used in protein expression studies, protein-protein interaction assays, and protein purification techniques such as affinity chromatography. The ha tag can be detected using specific antibodies or ligands that recognize the tag sequence, allowing for the isolation and study of the tagged protein.

Overall, the ha tag sequence is a useful tool for researchers to track, isolate, and study proteins of interest in a variety of experimental settings.
