The AlphaLISA® PER.C6® HCP Detection Kit is designed for the quantitative detection of PER.C6® contaminants in buffer and cell culture media using a homogeneous (no wash steps, no separation steps) assay.
For research use only. Not for use in diagnostic procedures.
The PER.C6® human cell line is utilized as an expression system for the industrial scale production of human recombinant proteins or biotherapeutics. The PER.C6® cell line has several advantages over other platforms, such as increased yield and improved safety of the final product. Biotherapeutics for human use must be extensively purified to remove undesired contaminants, such as host cell proteins, that could elicit toxic or immunological reactions. Therefore, there is a current need to quantitate and trace these unwanted host cell proteins in protein preparations with excellent sensitivity and robustness, while maintaining high throughput capabilities.
AlphaLISA technology allows the detection of molecules of interest in a no-wash, highly sensitive, quantitative assay. In an AlphaLISA assay, a biotinylated anti-analyte antibody binds to the Streptavidin-coated Donor beads while another anti-analyte antibody is conjugated to AlphaLISA Acceptor beads. In the presence of the analyte, the beads come into close proximity. The excitation of the Donor beads causes the release of singlet oxygen molecules that triggers a cascade of energy transfer in the Acceptor beads, resulting in a sharp peak of light emission at 615 nm.

The aim of this work was to compare the performance of the AlphaLISA® amplified luminescent proximity homogeneous assay technology platform and an alternative time-resolved fluorescenceresonance energy transfer (TR-FRET) technology assay platform for the detection of five biomarkers.
Biomarker levels were measured directly in CulturPlates-96 and-384 in a simple, fast, all-in-one-well AlphaLISA assay format. The elimination of transfer and wash steps simplifies cellular assays, reduces variability and significantly reduces hands-on time and costs associated with consumables. Integral plasma membrane (EGFR) and secreted solubleproteins (TNFa, IL1ß, IL6, IL8) were successfully determined, on adherent or suspension cells, using the standard AlphaLISA Immunoassay buffer.
The AlphaLISA® assay is a homogeneous immunoassay alternative to classical ELISA. AlphaLISA assays were originally utilized to detect analytesin cell cultures upernatants or serum/plasma samples.
Enzyme-linked Immunosorbent Assay is the most widely Kits adopted method for detection and quantification of cytokines and other biomarkers. This traditional technology offers good,selectivity, sensitivity and assay versatility; however, it has certain disadvantages such as limited dynamic range and low throughput due to the numerous wash steps.
