p73 Antibody (5B429) [CoraFluor™ 1]

CoraFluor™ 1, amine reactive (Catalog:7920) and CoraFluor™ 2, amine reactive (Catalog # 7950) are terbium-based probes that have been developed for use as TR-FRET donors. They emit wavelengths compatible with commonly used fluorescent acceptor dyes such as BODIPY® (or BDY) and Janelia Fluor® dyes, FITC (Catalog # 5440), TMR and Cyanine 5 (Catalog # 5436). CoraFluor™ fluorescence is brighter and more stable in biological media than existing TR-FRET donors, leading to enhanced sensitivity and improved data generation. CoraFluor™ 1 exhibits excitation upon exposure to a 337 nm UV laser.

p73 Antibody (5B429) [CoraFluor™ 1] Summary

• Description: CoraFluor(TM) 1 is a high performance terbium-based TR-FRET (Time-Resolved Fluorescence Resonance Energy Transfer) or TRF (Time-Resolved Fluorescence) donor for high throughput assay development. CoraFluor(TM) 1 absorbs UV light at approximately 340 nm, and emits at approximately 490 nm, 545 nm, 585 nm and 620 nm. It is compatible with common acceptor dyes that absorb at the emission wavelengths of CoraFluor(TM) 1. CoraFluor(TM) 1 can be used for the development of robust and scalable TR-FRET binding assays such as target engagement, ternary complex, protein-protein interaction and protein quantification assays.

• Immunogen: This antibody was raised against full-length human p73. It reacts with an epitope that is located on the N-terminal region of human p73. It does not cross react with p53.
• Specificity: p73 antibody (clone 5B429) recognizes all of the TAp73 isoforms i.e. isoforms with an intact NH2-terminal transactivation domain (Thottassery et el, 2006, PMID 16505115). Sayan et al 2005 (PMID 15781249) showed that p73 IMG-246/ NBP2-24737 reacted with all tested TAp73 isoforms but not deltaNp73 whereas p73 antibody clone 5B1288 (NB100-56674 / IMG-259A ) showed reactivity against all p73 isoforms including delta Np73. Caspase-cleaved p73 fragments, including 55 kDa and 45 kDa, have been described in literature (Sayan et al, 2008).

Background

p73 is a transcription factor that shares a significant amino acid identity with p53 and p63 (1). p73 and p63 can both activate p53-responsive genes and induce apoptosis upon over expression (2) Unlike p53, p73 is not induced by DNA damage and is not a target for inactivation by viral oncoproteins (3). Similar to p63, p73 has an additional coding region in the C-terminus (not found in p53) that can undergo complex alternative splicing giving rise to 3 splice forms (alpha, beta, and gamma) (4). Activation of p73 requires the presence of functional c-Abl. It has also be found that mutant p53 can bind to and inactivate p73 (5).
