Due to the rabbits superior immune system, they can generate antibodies with higher specificity, sensitivity, affinity, and diversity than those generated in more commonly used model species.
Basic Research
Non-rabbit mAbs often fail to detect difficult antigens (Ags) such as small molecules, Ags with highly similar epitopes, post-transcriptionally-modified Ags, and Ags with no immunogenicity in mice. They also tend to require stringent optimization protocols in order to work in certain applications, possibly affecting the overall effectiveness of the experiment and interpretation of the results.

Diagnostics
In Vitro Diagnostics: A variety of In Vitro diagnostic (IVD) assays, such as IHC, ELISA, and radio immunoassays (RI) are based on the principles of antigen-antibody binding. Given the critical role these assays play in patient and animal care, it is extremely important that IVD assays are carried out using the highest sensitivity and affinity mAbs available.
In Vivo Imaging: Visualization of mAbs can be accomplished through numerous means; however, the most common method is through labelling of mAbs with radioactive or fluorescent molecules to help track them in the body and aid in quantifying the results.

Therapeutics
Anti-Idiotype Antibodies: Pharmacokinetic (PK) assays are used to measure the absorption and excretion rates, distribution, and half-life of candidate small molecules or mAb therapeutics. Results from these assays help identify the optimal dose and toxicity risks of a therapeutic molecule. Therefore anti-idiotype antibodies need to be sensitive enough to capture trace amounts of their antibody target in free, bound, and total forms in biological fluid samples.
mAb therapeutics: The high specificity and sensitivity of an antibody towards its target antigen reduces both safety and toxicity concerns: highly specific antibodies avoid off-target binding and hence, offer safety; highly sensitive antibodies require low dosage administration and hence, cause a minimum level of toxicity.
