Our Abpromise guarantee covers the use of ab32206 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.
WB Use a concentration of 1 µg/ml. Detects a band of approximately 93,75,54 kDa (predicted molecular weight: 83 kDa).

The 93 kDa band corresponds to Isoform 1 of Gephyrin as observed in the literature. We suspect that the 75 kDa band corresponds to another isoform of Gephyrin. The identity of the 54 kDa band is unknown. All three of the bands we observe on WB are partially blocked by addition of the immunising peptide (ab32205).


  • Function
    Microtubule-associated protein involved in membrane protein-cytoskeleton interactions. It is thought to anchor the inhibitory glycine receptor (GLYR) to subsynaptic microtubules (By similarity). Catalyzes two steps in the biosynthesis of the molybdenum cofactor. In the first step, molybdopterin is adenylated. Subsequently, molybdate is inserted into adenylated molybdopterin and AMP is released.
  • Pathway
    Cofactor biosynthesis; molybdopterin biosynthesis.
  • Involvement in disease
    Defects in GPHN are the cause of molybdenum cofactor deficiency type C (MOCOD type C) [MIM:252150]. MOCOD type C is an autosomal recessive disease which leads to the pleiotropic loss of all molybdoenzyme activities and is characterized by severe neurological damage, neonatal seizures and early childhood death.
    Defects in GPHN are a cause of startle disease (STHE) [MIM:149400]; also known as hyperekplexia. STHE is a genetically heterogeneous neurologic disorder characterized by muscular rigidity of central nervous system origin, particularly in the neonatal period, and by an exaggerated startle response to unexpected acoustic or tactile stimuli.
  • Sequence similarities
    In the N-terminal section; belongs to the moaB/mog family.
    In the C-terminal section; belongs to the moeA family.
  • Cellular localization
    Cell junction > synapse. Cell junction > synapse > postsynaptic cell membrane. Cytoplasm > cytoskeleton. Cytoplasmic face of glycinergic postsynaptic membranes.

    Developed using the ECL technique.

    Performed under reducing conditions.

    Predicted band size: 83 kDa
    Observed band size: 90 kDa
    why is the actual band size different from the predicted?

    Exposure time: 20 minutes

    We are unsure of the identity of the 89kDa band observed in brain lysates, however this was consistent across both species tested. 

    Abcam recommends using milk as the blocking agent. Abcam welcomes customer feedback and would appreciate any comments regarding this product and the data presented above.

  • Immunofluorescent staining for Gephyrin in rat brain cortex using Rabbit polyclonal to Gephyrin (ab32206; 1/1000). The staining is located in the cytoplasm and in some of the processes of cortical neurons. This staining is observed in many other brain areas. The picture was acquired using a X20 objective. Protocol details: Rats were intracardially perfused with 4% paraformaldehyde. Whole brain tissue was post-fixed overnight in the same fixative, and cryoprotected in 20% sucrose and frozen in OCT. 30 µm coronal sections were cut by cyrostat for use in fre floating IHC. Primary antibody ab32206 was incubated overnight at 1/1000 at room temperature. Secondary antibody Alexa fluor® 488 1/1000 was incubated for 2 hours at room temperature.

  • ICC/IF image of ab32206 stained PC-12 (Rat adrenal gland pheochromocytoma cell line) cells. The cells were fixed in 100% methanol for 5 minutes and then incubated in 1% BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1 hour to permeabilize the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab32206, 1 µg/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 1 hour. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1 hour. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43 µM.
