pIMAGO-Biotin for Western Blot HRP Based Detection (ECL)

pIMAGO is a universal phosphoprotein detection technology, that is a reliable alternative to phosphoantibodies for Western blot or ELISA, and a safe and cost effective alternative to ³²P radioactive assays. It enables sensitive and specific recognition of phosphorylated molecules.

Unlike phosphoantibodies, the binding is not biased by amino acid sequence, and therefore can be used for detection of any phosphorylation event on any protein site. The pIMAGO detection protocol resembles a simple Western blot procedure and is easy to incorporate into any laboratory.

Features:

• • • Universal detection – Detection in any organism / sequence / amino acid through Ti⁴⁺
    • High specificity – Multiple Ti⁴⁺ ensure strong binding to resist harsh washing
    • High sensitivity – Multiple biotin ensures significant signal amplification (100pg)
    • Multiplex capability – Small size (4nm) allow multiplexing with total protein antibodies
    • Flexibility – Avidin–HRP /  Fluor 550 / Fluor 680 / Fluor 800 available for detection.

Results and Data:

pIMAGO is based on water soluble, globular nanopolymers (i.e., dendrimers) that are multifunctionalized with reactive groups (e.g., Ti(IV) ions) for the highly specific recognition of phosphate groups, and with “reporting” groups (e.g., biotin, fluorophore) that facilitate their detection. Multiple functionalized groups per dendrimer ensure very strong binding to the phosphoproteins (resulting in high specificity) and significant signal amplification from many “reporting” groups (resulting in high sensitivity).
