Product Information

Product Usage Information

Application Dilution
Western Blotting 1:1000

Storage

Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA, 50% glycerol and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.

Specificity / Sensitivity

PLSCR1 (E4Z8R) Rabbit mAb recognizes endogenous levels of total PLSCR1 protein. In addition to the predicted 35 kDa band observed, PLSCR1 (E4Z8R) Rabbit mAb detects multiple bands spanning 45-100 kDa representing post-translationally modified PLSCR1, including lipidated forms of the target protein.

Species Reactivity:

Human

Source / Purification

Monoclonal antibody is produced by immunizing animals with recombinant protein specific to the amino terminus of human PLSCR1 protein.

Background

Phospholipid scramblase 1 (PLSCR1) is 1 of 4 scramblases encoded in the human genome (1). Phospholipid scramblases function to catalyze calcium-mediated ATP-independent mobilization of phospholipids between the inner and outer leaflet of plasma membrane in activated, injured, or apoptotic cells. PLSCR1 is a type-II transmembrane protein with a short 9 amino acid C-terminal domain and a long N-terminal extracellular domain. Although PLSCR1 is part of a family of proteins that function to catalyze phospholipid mobilization, PLSCR1 may have alternative functions (2,3). Rather, PLSCR1 may function to activate cell signaling pathways, particularly in phagocytic cells of monocyte/macrophage lineage (4). Microglia, resident macrophages of the brain, play a key role in clearance of cellular and pathologic debris where altered phagocytosis may contribute to neurodegenerative diseases like Alzheimer’s disease. PLSCR1 may regulate microglia phagocytosis, representing a potential therapeutic target to modulate microglia phagocytosis (5).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
