Our Abpromise guarantee covers the use of ab236632 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
RelevanceHuman 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 was immunoprecipitated from 0.35 mg HEK-293T (human embryonic kidney) transfected with TIM 4 (WT) expression vector containing a HA-GFP-tag and PDGFR TM domain whole cell lysate 10µg with ab236632 at 1/30 dilution (2µg in 0.35mg lysates). Western blot was performed on the immunoprecipitate using ab236632. VeriBlot for IP Detection Reagent (HRP) (ab131366) was used at 1/2000 dilution.

Flow cytometric analysis of 4% paraformaldehyde fixed, 90% methanol permeabilized HEK-293T (human embryonic kidney) transfected with TATA-box-binding protein (WT) expression vector containing HA-tag (Right) / HEK-293T (Left) cells labeling HA tag with ab236632 at 1/600 dilution. A Goat anti rabbit IgG (Alexa Fluor® 488, ab150077) at 1/2000 dilution was used as the secondary antibody.
Immunofluorescent analysis of 4% paraformaldehyde-fixed, 0.1% Triton X-100 permeabilized HEK-293T (human embryonic kidney epithelial cell) transfected with HA-tagged TATA-box-binding protein (WT) expression vector labeling HA tag with ab236632 at 1/1000 (0.6 µg/ml) dilution, followed by ab150077 AlexaFluor®488 Goat anti-Rabbit secondary antibody at 1/1000, (2 µg/ml) dilution (Green). Confocal image showing nuclear staining in HEK-293T cells transfected with HA-tagged TATA-box-binding protein (WT) expression vector is observed. Anti-HA.11 Epitope Tag antibody (Alexa Fluor® 647) was used to counterstain tubulin at 1/200 dilution (Red). The nuclear counterstain was DAPI (Blue).
Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is ab150077 AlexaFluor®488 Goat anti-Rabbit secondary at 1/1000 (2 µg/ml) dilution.
