Relevance
Human influenza hemagglutinin (HA) is a surface glycoprotein required for the infectivity of the human virus. The HA tag is derived from the HA molecule corresponding to amino acids 98-106 has been extensively used as a general epitope tag in expression vectors. Many recombinant proteins have been engineered to express the HA tag, which does not appear to interfere with the bioactivity or the biodistribution of the recombinant protein. This tag facilitates the detection, isolation, and purification of the proteins.

HA tag Mouse mAb (Ab106776) - IF/ICC
IF image of HA tag Mouse mAb (Ab106776) stained HEK293T cells, transfected with pcDNA3.1-HA-Flag-p62. The cells were 4% para-formaldehyde fixed (20 min) and then incubated in 10% normal goat serum for 1 h to permeabilise the cells and block non-specific pro-tein-protein interactions. The cells were then incubated with the HA tag Mouse mAb (Ab106776) (1/200) and the antibody Flag-tag pAb(1/200) at 5 µg/mL overnight at 4°C. The secondary anti-body (Red) was Goat anti-Mouse IgG (H+L)-TRITC and the secondary antibody (Green) was Goat anti-Rabbit IgG (H+L)-FITC used at 1/1000 dilution for 1 h. Hoechst33342 was used to stain the cell nuclei (blue).
