RabMabs - Rabbit Monoclonal Antibodies
Advantages of Rabbit Monoclonals
• More diverse epitope recognition
• Improved immune response to small-size epitopes
• High specificity and affinity
• Greatly improved response to mouse antigens
|
|
To put it simply - better antigen recognition. The rabbit immune system generates antibody diversity and optimizes affinity by mechanisms that are more efficient than those of mice and other rodents. This increases the possibility of obtaining a functional antibody that will work in a variety of applications. Additionally, many small compounds and peptides do not elicit a good immune response in mice but do so in rabbits. It is often for this reason, that rabbit polyclonal antibodies are developed and used in many research and even some diagnostic applications, ranging from drug screening to clinical diagnosis. As an example of this, most of the phospho specific recognition antibodies being sold on the market today are rabbit polyclonals.

Antigen recognition |
• Limited immuno response
• Small molecules/peptides often non-immunogenic
• Very limited response to rodent antigens
• Recognizes limited number of epitopes (due to immunodominance)
|
• High chance of success with range of antigens including small molecules and peptides
• Good response to use rodent proteins
• Recognizes several epitopes per protein antigen

Affinities |
Nanomolar (~10 -9 Kd M) |

So what do these advantages mean to you ?
With rabbit monoclonal antibodies you get the combined benefits of superior antigen recognition with the specificity and consistency of a monoclonal antibody, bringing you the highest possible quality antibody.Wide range of applications possible – RabMab’s have been shown to perform in a wide range of applications. Every one of our antibodies is screened and tested using ELISA, western blotting as well as ICC and IHC. Additionally many of our antibodies have been tested for use in Flow Cytometry. Antibodies available from most vendors are initially only tested for use in western blotting and so the use of the antibody in other applications is often not validated.
