Palm PCR™ COVID-19 Fast Real-time RT-PCR Kit ❖ Assay Format and Product Components ➢ Two Assay Format: Assay 1 using Premix 1 for detecting E gene that is common to Sarbecovirus; and Assay 2 using Premix 2 for detecting RdRP gene that is specific to SARS-CoV-2 ➢ Each assay contains an internal control (IC) to exclude the possibility of false-negative results due to inefficient or false RNA extraction. Product Components Component Premix 1 for E gene (lyophilized) Premix 2 for RdRP gene (lyophilized) Reconstitution buffer Positive Control Negative Control ❖ Lyophilized Premix Format - Robust and...
