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 5 µg/ml.
IHC-Fr Use at an assay dependent concentration.
WB Use a concentration of 1 µg/ml. Predicted molecular weight: 76 kDa. Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
IHC-P Use a concentration of 5 µg/ml.


  • Function
    Plays an important role in spindle pole orientation. Interacts and contributes to the functional activity of G(i) alpha proteins. Acts to stabilize the apical complex during neuroblast divisions.
  • Tissue specificity
    Ubiquitously expressed.
  • Involvement in disease
    Defects in GPSM2 are the cause of deafness autosomal recessive type 82 (DFNB82) [MIM:613557]. DFNB82 is a form of non-syndromic deafness characterized by prelingual, bilateral, severe, sensorineural hearing loss. There are no symptoms of vestibular dysfunction.
  • Sequence similarities
    Belongs to the GPSM family.
    Contains 4 GoLoco domains.
    Contains 8 TPR repeats.
  • Cellular localization
    Cytoplasm. Cytoplasm > cell cortex. Localizes in the cytoplasm in the interphase and at cell periphery in the metaphase.

    Predicted band size: 76 kDa
    Observed band size: 85 kDa (why is the actual band size different from the predicted?)

    Gel concentration: 12%
  • ICC/IF image of ab84571 stained MCF7 cells. The cells were 4% formaldehyde fixed (10 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 (ab84571, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) 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.
