WebJan 10, 2024 · When choosing the secondary antibodies you have to remember that each of them specifically recognizes only one primary antibody. Furthermore, the fluorochromes in this example of the three secondary antibodies must differ in their wavelength spectrum to discriminate their fluorescence signal in microscopic analysis. WebNov 16, 2024 · When choosing a primary antibody, first, remember that antibodies recognize very specific 3-dimensional epitopes. Different sample processing steps can alter epitopes in different ways, so antibodies that work in one context may not work in another. Try to choose primary antibodies that have been validated in either IF, IHC, or ICC.
