Antibody pairs and proteins for immunoassays
Monoclonal antibody sandwich pairs. The capture antibody and detection antibody are both monoclonal in origin. Two monoclonal antibodies ensures higher specificity compared with assays with a single antibody.
BioTimes's recombinant proteins are mostly human cell-expressed. Human cell expression ensures proper folding, glycosylation, gamma-carboxylation and other post-translational modification of recombinant proteins.
