The ResiQuant® Recombinant Protein A ELISA Kit is a highly sensitive and quantitative ELISA kit. This kit is specifically intended for the detection of process-related impurities recombinant Protein A residuals in the manufacturing of therapeutic monoclonal antibodies or other Fc-fusion recombinant proteins. The limit of detection (LOD) for this kit is 13.7 pg/mL, and the limit of quantitation (LLOQ) is 41.2 pg/mL. It is suitable for use throughout the manufacturing process as well as for product release.
Features
· Sensitive: 13.7 pg/ml serves as the Limit of Detection (LOD), while the Lower Limit of Quantification (LLOQ) is set at 41.2 pg/ml. Additionally, the spiking recovery rate meets the required standards, falling within the acceptable range of 80% to 120%.
· Residual Protein A Isolation: protein A is a highly thermostable protein. Taking the advantage to separate the residual protein A from the test samples, the assay is able to reach the best LOD.
· Fast to result: No complicated steps; the entire experimental process takes 2.5 hours.
