Our Abpromise guarantee covers the use of ab89650 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
ICC/IF Use a concentration of 1 µg/ml.
IP Use a concentration of 5 µg/ml.
WB Use a concentration of 1 µg/ml. Detects a band of approximately 121 kDa (predicted molecular weight: 121 kDa).


  • Function
    Non-neuronal microtubule-associated protein. Promotes microtubule assembly.
  • Sequence similarities
    Contains 4 Tau/MAP repeats.
  • Post-translational
    Phosphorylated upon DNA damage, probably by ATM or ATR (By similarity). Phosphorylation on Ser-787 negatively regulates MAP4 activity to promote microtubule assembly. Isoform 3 is phosphorylated on Ser-337 and Ser-338.
  • Cellular localization
    Cytoplasm > cytoskeleton.

  • MAP4 was immunoprecipitated using 0.5mg Hela whole cell extract, 5µg of Rabbit polyclonal to MAP4 and 50µl of protein G magnetic beads (+). No antibody was added to the control (-).

    The antibody was incubated under agitation with Protein G beads for 10min, Hela whole cell extract lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation.

    Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70°C; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab89650.

    Secondary: Mouse monoclonal [SB62a] Secondary Antibody to Rabbit IgG light chain (HRP) (ab99697).

    Band: 121kDa; MAP4

  • All lanes : Anti-MAP4 antibody (ab89650) at 1 µg/ml

    Lane 1 : Human testis tissue lysate - total protein (ab30257)
    Lane 2 : Human spinal cord tissue lysate - total protein (ab29188)

    Lysates/proteins at 10 µg per lane.

    All lanes : Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution

    Developed using the ECL technique.

    Performed under reducing conditions.

    Predicted band size: 121 kDa
    Observed band size: 121 kDa
    Additional bands at: 105 kDa (possible isoform)

    Exposure time: 8 minutes
  • ICC/IF image of ab89650 stained HeLa cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab89650 at 1µg/ml overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti- rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM. This antibody also gave a positive result in HepG2 methanol fixed cells at 1ug/ml
