  • Function
    Catalyzes the deacetylation of N-acetylaspartic acid (NAA) to produce acetate and L-aspartate. NAA occurs in high concentration in brain and its hydrolysis NAA plays a significant part in the maintenance of intact white matter. In other tissues it act as a scavenger of NAA from body fluids.
  • Tissue specificity
    Brain white matter, skeletal muscle, kidney, adrenal glands, lung and liver.
  • Involvement in disease
    Defects in ASPA are the cause of Canavan disease (CAND) [MIM:271900]; also known as spongy degeneration of the brain. CAND is a rare neurodegenerative condition of infancy or childhood characterized by white matter vacuolization and demeylination that gives rise to a spongy appearance. The clinical features are onset in early infancy, atonia of neck muscles, hypotonia, hyperextension of legs and flexion of arms, blindness, severe mental defect, megalocephaly, and death by 18 months on the average.

  • ab97454 stained U-87 MG cells. The cells were 100% methanol fixed for 5 minutes at -20°C and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1hour at room temperature to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab97454 at 5µg/ml) overnight at +4°C. The secondary antibody (pseudo-colored green) was Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed (ab150081) used at a 1/1000 dilution for 1hour at room temperature. Alexa Fluor® 594 WGA was used to label plasma membranes (pseudo-colored red) at a 1/200 dilution for 1hour at room temperature. DAPI was used to stain the cell nuclei (pseudo-colored blue) at a concentration of 1.43µM for 1hour at room temperature.

  • ASPA was immunoprecipitated using 0.5mg MOLT4 whole cell extract, 5µg of Rabbit polyclonal to ASPA 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, MOLT4 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 ab97454.

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

    Band: 36kDa, non specific bands - 42 and 51kDa: We are unsure as to the identity of this extra band; ASPA

  • All lanes : Anti-ASPA antibody (ab97454) at 1/1000 dilution

    Lane 1 : MOLT4 whole cell lysate
    Lane 2 : Raji whole cell lysate

    Lysates/proteins at 30 µg per lane.

    Predicted band size: 36 kDa
