Transmembrane AntibodyTransmembrane Antibody
Self AntigenSelf Antigen
FluorescenceFluorescence
TBDTo be determined
ExtractionExtractionSeparating the analyte of interest from other components of the sample matrix to minimize interference
PurificationPurificationIsolation of the target analyte to enhance specificity and accuracy of detection
DilutionDilutionAdjusting the concentration of the sample to fit within the detection range of the immunoassay
Enzyme InactivationEnzyme InactivationRemoving or inactivating enzymes in the sample that could interfere with the enzymatic reactions
