    Testis and brain.
  • Sequence similarities

    Belongs to the GST superfamily. Mu family.
    Contains 1 GST C-terminal domain.
    Contains 1 GST N-terminal domain.
  • Post-translational

    The N-terminus is blocked.

  • ICC/IF image of ab74749 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 ab74749 at 5 µg/mL overnight at +4°C. The secondary antibody (green) was DyLight® 488 Goat anti-Rabbit IgG (H+L) (ab96899) used at a 1/250 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.

You have been using the product at a very low concentration (1/10,000). We recommend on our datasheet to use at a starting concentration of 1/1000, in this particular case you may find that you may need an even higher concentration and we recommend to titer the antibody in a range from 1/100-1/1000.

The short peptide sequence that was used to raise this antibody is 14aa in length, 100% homologous to this protein (http://www.uniprot.org/uniprot/P21266) and contained within this larger 50aa sequence: EEKIRVDIIENQVMDFRTQLIRLCYSSDHEKLKPQYLEELPGQLKQFSMF. I would like to offer some suggestions to help optimize the results from ab74749. I see you have used this product at 1/10,000 dlution. We recommend a starting dilution of 1/1000 when using this in western blot and to incubate the antibody overnight at +4C.
