1 High modification specificity: recognizes protein ubiquitination (mono-/polyubiquitination), distinguishes ubiquitinated/non-ubiquitinated proteins, no cross-reactivity with other post-translational modifications.
2 Broad type coverage: some recognize polyubiquitination of different chains (e.g., K48, K63), suitable for studies on ubiquitination-mediated degradation, signal transduction, etc.
3 Strong anti-interference ability for complex samples and experimental conditions.
4 Rigorous multi-dimensional validation.
