WebbIn direct detection methods, the primary antibody is directly conjugated to a label. During indirect detection, the primary antibody is bound by a labeled secondary antibody that has been raised against the host species of the primary antibody. Indirect methods may also include amplification steps to increase signal intensity. Webb3 feb. 2016 · You can keep it simple. Using a directly-labeled primary antibody keeps your assay simple. There are less steps involved so it decreases your chances of messing up. It gives you fewer steps to trouble shoot when things don’t go as planned. And there are fewer reagents to quality-control. Variability is reduced.
