​​Pre-adsorbed secondary antibodies are ideal for eliminating potential antibody species cross-reactivity. Pre-adsorption of the antibody should be performed using serum from the same species as your sample. Thus, species-adsorbed antibodies are less likely to interact with endogenous immunoglobulins, reducing significantly non-specific binding We provide a wide range of pre-adsorbed Alexa Fluor conjugated secondary antibodies.
