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

FLASH/CASP8AP2 (D3T8Q) Rabbit mAb recognizes endogenous levels of total FLASH/CASP8AP2 protein.

Source / Purification

Monoclonal antibody is produced by immunizing animals with recombinant protein specific to residues near the amino terminus of human FLASH/CASP8AP2 protein.

Background

FLICE associated huge protein (FLASH), also termed Caspase 8 associated protein 2 (CASP8AP2), is a large multifunctional protein that has been shown to be involved in multiple processes, including apoptosis, cell cycle progression, and transcriptional regulation (1-3). It was originally identified as a component of the FAS-FADD-Caspase 8 complex with a role in the activation of caspase-8 during Fas-mediated apoptosis (1). However, studies suggest additional functions for FLASH/CASP8AP2 in the nucleus within Cajal and PML bodies (3-5). One of the functions identified was its ability to regulate histone gene processing and S-phase progression (3,6). FLASH/CASP8AP2 has also been found to regulate the activity of transcription factors, including the glucocorticoid receptor and c-Myb (2,7). Furthermore, FLASH/CASP8AP2 was found to stabilize the expression of ZEB1, a transcriptional repressor of genes associated with epithelial-to-mesenchymal transition (EMT), a process associated with cancer metastasis (8). Aberrant expression as well as genetic mutations in the FLASH/CASP8AP2 gene have been described in several cancers and it has been suggested to be a prognostic indicator in acute lymphoblastic leukemia (9-14).

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.
