  • Title: Immuno-polymerase chain reaction as a unique molecular tool for detection of infectious agents.
    Author: Barletta J, Bartolome A.
    Journal: Expert Opin Med Diagn; 2007 Oct; 1(2):267-88. PubMed ID: 23489312.
    Abstract:
    Theoretically, the immuno-polymerase chain reaction (IPCR) method is the most sensitive technique for the detection of proteins and gains its uniqueness through the exponential amplification of a signal-generating nucleic acid intermediate attached to a protein target. This method is similar to PCR for the detection of nucleic acid targets, and has now been shown to offer the ability to detect infectious agents where nucleic acids are not present. Although the technical development of IPCR has taken a torturous path down a winding avenue of encouraging advances, the method remains rarely utilized by the scientific community and completely unused as a clinical diagnostic test approved by a national accrediting agency. Although the use of real-time instrumentation has enhanced the performance of IPCR to higher levels of statistical accuracy and reproducibility, as compared with the conventional method, its application remains limited by the high standards required for clinical diagnoses of infectious diseases. This review summarizes experimental data published to date describing the utilization of the IPCR method as it relates to the detection and diagnosis of human infectious disease, and examines the progressive development of this method, as well as the factors impeding its universal application as a clinical diagnostic tool. With further standardization and validation, the IPCR method has the potential to become the most analytically sensitive method available for the detection of target proteins of infectious diseases.
