Invitrogen™ Mouse LAP/TGFb ProQuantum Immunoassay Kit

Description

Utilizing proximity-based amplification technology, the assay combines the analyte specificity of high-affinity antibody-antigen binding with the signal detection and amplification capabilities of real-time PCR to achieve a simple yet powerful next-generation protein quantitation platform. A user-friendly workflow combined with intuitive software for analytics enables sample-to-answer in just 2 hours.

• High sensitivity-detect low levels of protein with greater sensitivity than traditional methods
• Broad dynamic range-≥5 logarithmic units, minimizing sample dilutions to ensure they fall within the range
• Small sample consumption-use 2–5 μL of sample (compared to 75 μL for triplicate wells with other methods)
• Fast, easy workflow-2 hours from sample to answer, with no wash steps
• No proprietary instrument to purchase-runs on any real-time PCR instrument

TGF beta-1 is a polypeptide member of the transforming growth factor beta superfamily of cytokines, found almost ubiquitously in tissues. Transforming growth factor (TGF)-b is stored in the extracellular matrix as a latent complex with its prodomain. Activation of TGF-b1 requires the binding of aV integrin to an RGD sequence in the prodomain and exertion of force on this domain, which is held in the extracellular matrix by latent TGF-b binding proteins. Latent forms are complexes of TGF-beta, an aminoterminal portion of the TGF-beta precursor, designated TGF-LAP (TGF-latency associated peptide), and a specific binding protein, known as LTBP.
