PLSCR1 (Phospholipid Scramblase 1) is a multiply palmitoylated endofacial plasma membrane protein containing several SH3 and WW domain binding motives. In the plasma membrane, PLSCR1 plays a role in transbilayer lipid redistributions and signal transduction. Nonpalmitoylated PLSCR1, however, is able to be transported into the nucleus and bind DNA. PLSCR1 potentiates the antiviral activity of interferon and its expression is highly induced by interferons and growth factors.


The antibody 13A6 [TEC-23] binds to rat Phospholipid Scramblase 1 (PLSCR1), an 37-49 kDa membrane-associated protein accelerating bidirectional movement of plasma membrane phospholipids during conditions of elevated calcium.

Regulatory Status


BALB/c mice were immunized with pooled lipid rafts isolated from RBL-2H3 cells. Hybridoma cells were obtained after fusion of SP02 mouse myeloma cells with spleen cells of immunized mice using standard procedures.

Species Reactivity:

  • Rat

Negative Species:


  • Immunoprecipitation
  • Western Blotting
    Recommended dilution: 1 μg/ml
    Positive control: RBL rat basophilic leukemia cell line
    Sample preparation: Resuspend approx. 50 mil. cells in 1 ml cold Lysis buffer (1% Triton X-100 in 20 mM Tris/Cl, 100 mM NaCl, 2 mM EDTA, 2 mM Na3Vo4, 10 mM glycerolphosphate, pH 8.0, 1 mM PMSF, 10 μg/ml aprotinin). Incubate 20 min on ice. Centrifuge to remove cell debris. Mix lysate with non-reducing/reducing Laemmli SDS-PAGE sample buffer. Boil for 5 min.
    Application note: Both reducing and non-reducing conditions.
