Sensitivity: The minimum detectable dose of Rat PCSK9 was determined to be approximately 47 pg/ml. This is defined as at least three times standard deviations above the mean optical density of 10 replicates of the zero standard. Detection: 47 pg/ml
Sensitivity: 0.05 ng/ml Detection: The assay measures active Serpin E1/PAI-1 in the 0.05-50 ng/ml range. Samples giving Serpin E1/PAI-1 levels above 50ng/ml should be diluted in 3% BSA blocking buffer.
