| NPX | NPX, Normalized Protein eXpression, is Olink's arbitrary unit which is in Log2 scale. It is calculated from Ct values and data pre-processing (normalization) is performed to minimize both intra- and inter-assay variation. NPX data allows users to identify changes for individual protein levels across their sample set, and then use this data to establish protein signatures. The NPX scale is inverted compared to that of Ct. This means that a high NPX value equals a high protein concentration. Because NPX is in a log2 scale, a 1 NPX difference means a doubling of protein concentration. If needed NPX values can be converted into linear scale: 2^NPX= linear NPX. | | |

| PFU | Plaque-forming unit. A measure of viable infectious entities (e.g. viral particles or group of particles) in the specimen or product defined as the smallest quantity that can produce a cytopathic effect in the host cell culture challenged with the defined inoculum, visible under the microscope and/or to the naked eye as a plaque. A number of plaque forming units (PFU) per unit volume is a conventional way to refer the titer of an infective entity in a specimen or preparation. | | |
