    Anti-HA tag antibody [4C12]
    See all HA tag primary antibodies
  • Description
    Mouse monoclonal [4C12] to HA tag
  • Host species
  • Specificity
    The antibody detects HA-tag fused to the C-terminus or N-terminus of targeted proteins in transfected cells. The antibody works in ChIP but less well than ab9110 (see ChIP data).
  • Tested applications

  • 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.

  • This picture shows baby hamster kidney cell expressing HA-tag CFTR protein. This type of cells were grown on coverslip and immunofluorescence was performed. Dilution of 1:200 was used and incubated for 2hrs with antibody.

  • Recombinant HA-tagged Rab6 was immunoprecipitated from 1 mg transfected HEK-293T (human epithelial cell line from embryonic kidney transformed with large T antigen) whole cell extract with 2 μL ab1424.

  • Xenopus laevis oocytes were injected with mRNA for HA-tagged human BORIS. Chromatin was prepared according to the Abcam X-ChIP protocol. Oocytes were fixed with formaldehyde for 10min. The  ChIP was performed with 25µg of chromatin, 3µg of ab1424 (anti-HA, light blue)  and 3µg of ab18337 (anti-BORIS, dark blue), and 20µl of Protein A/G sepharose beads. A non-specific antibody was used as a control (yellow). The immunoprecipitated DNA was quantified by real time PCR (Taqman approach).
