General description

SG2NA, also known as Striatin 3, was identified as a human cancer auto-antigen and has not been implicated in vesicular trafficking and signal tranduction. It is highly related to striatin and zinedin (striatin 4). It is a cytoplasmic scaffolding protein that binds to Calmodulin and PP2A A and C subunits as well as the human homolog of the yeast protein, Mob1, which appears to modulate PP2A activity.


Reacts with SG2NA. No cross reactivity with striatin.


Synthetic peptide from SG2NA.


Immunocytochemistry: A previous lot of this antibody was used in immunocytochemistry at a 1:500 dilution.

Immunoprecipitation: A previous lot of this antibody was used in IP; 3 μL is a recommended as starting point for immunoprecipitation.
Optimal working dilutions must be determined by end user.

Target description

The antibody recognizes the ~93 kDa SG2NA protein in Jurkat cell lysate. In some cell types a band of ~70 kDa is also recognized, which may be an alternatively spliced form of SG2NA or another unknown protein.

Physical form

Mouse monoclonal IgG1 ascites containing 40% glycerol and 0.02% sodium azide.

Storage and Stability

Stable at -20°C in undiluted aliquots for up to 1 year from date of receipt. For long-term storage, may be stored at -80°C.
Handling Recommendations: Upon first thaw, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.
