Why Choose Rabbit Monoclonal Antibodies Over Others?

Why are rabbit monoclonal antibodies the optimal choice instead of the alternative standard polyclonal or monoclonal antibodies like mouse or rat? This article will describe antibodies and why they are so critical to medical and scientific research.

Antibody Selection using DNA Origami Scaffolds

Mammalian antibodies typically have two arms that can bind to two individual antigen molecules. But what is the optimal antigen distance, and does the doubled antigen-binding region improve antibody binding strength? Scandinavian researchers have recently measured the optimal antigen-distances for different antibody classes by presenting controllable antigen patterns on DNA-origami scaffolds.

	Using Phage Display for Antibody Discovery and Development In phage-display, a gene encoding the surface protein of a bacteriophage is replaced with a gene encoding a novel protein. The technique can be used in drug discovery and research for the investigation of novel polypeptides. The discovery of phage display was spurred on by the discovery that filamentous phages can be synthetically engineered to exhibit amino acid sequences of foreign origin on the phage-coat proteins, without affecting the infectivity of the chosen phage.

	Improving Antibody Affinity Using CRISPR Human blood samples can be used to produce antibodies against an antigen of interest. Since the blood contains antigen-presenting immune cells, antibody identification only requires a binding assay to identify the cells presenting suitable antibodies. However, this selects for “early” antibodies, which in the organism would undergo maturation by multiple rounds of mutation and selection, leading to antibodies that are more effective in antigen-binding.

	Improved antibody validation Antibodies are used in a variety of clinical and research situations to examine the structure and function, and distribution of proteins. However, many researchers have found a lack of specificity in the functioning of these antibodies. This means that any work conducted using these antibodies will not yield reliable results.
