General description

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 that corresponds to amino acids 98-106. It 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.

Specificity

Reactivity with other species has not been confirmed.
Recognizes recombinant proteins containing the HA epitope tag. The apparent molecular weight is related to the tagged protein.

Immunogen

KLH-conjugated, synthetic peptide containing the sequence …CYPYDVPDY… derived from the influenza virus hemaglutinin (HA) protein.

Application

Anti-HA Tag Antibody, clone DW2 is an antibody against HA Tag for use in WB.

Western Blot Analysis: A 1:1,000-1:2,000 dilution of this lot detected HA-tagged WNT-1 protein expressed in HEK293 cells.

Quality

Western Blot Analysis
Lysates from non-transfected (lane 1) and HAtagged WNT-1 transfected (lane 2) HEK293 cells were resolved by electrophoresis, transferred to nitrocellulose and probed with anti-HA-Tag, clone DW2 (1:1,000 dilution).
Proteins were visualized using a goat anti-rabbit secondary antibody conjugated to HRP and a chemiluminescence detection system.

Arrow indicates the HA-tagged protein (~49 kDa). The apparent molecular weight is related to the tagged protein.

Storage and Stability

Stable for 1 year at -20°C from date of shipment. Handling Recommendations: Upon receipt, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.

Analysis Note

Control
HA-tagged WNT-1 protein.
