#ALT# ADA/PK Development and Custom Antibody Lab Services

An idiotope is the unique set of antigenic determinants (epitopes) of the variable portion of an antibody. An anti-idiotypic (Anti-ID) antibody binds to the idiotope of another antibody, usually an antibody drug, which makes it a very powerful tool for antibody drug development, especially for immunogenicity and PK/PD analysis. ACROBiosystems has developed a series of high-affinity anti-idiotypic antibodies and ADA/PK services along with many other custom antibody lab services.

    KeysightExpert Advice on Producing Anti-VHH Antibodies and Nanobodies
Nanobodies carry several advantages, but their production can be laborious. In this interview, Dr. Dave Fancy discusses the biggest challenges that scientists face when generating nanobodies and explains how anti-alpaca secondary antibodies can be used to produce high-affinity nanobodies and VHH domain libraries.

   Using Phage Display for Antibody Discovery and DevelopmentUsing 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.
 VHH Antibodies (Nanobodies) Advantages and Limitations
VHH Antibodies (Nanobodies) Advantages and LimitationsNanobodies are antibodies with a single variable domain located on a heavy chain, also known as VHH antibodies. Nanobodies are often seen as an alternative to conventional antibodies, and have significant differences in both production and use that influence their suitability.
 Improving Antibody Affinity through using CRISPR
Improving Antibody Affinity through using CRISPRHuman 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.
 Current and Future Applications of Rabbit Monoclonal Antibodies
Current and Future Applications of Rabbit Monoclonal AntibodiesIn most clinical applications, the monoclonal antibodies (mAbs) used are of murine origin; however, the small spleen of the mouse is limited in its ability to generate antibodies. Also, the mice used for laboratory experiments are usually inbred in a controlled environment, further restricting their ability to demonstrate diverse immune responses.
 HIV Suppression Using Adenovirus-Mediated Gene Therapy
HIV Suppression Using Adenovirus-Mediated Gene TherapyResearch on therapies against the Human Immunodeficiency Virus (HIV) has repeatedly demonstrated the potential of broadly neutralizing antibodies (bn-Abs) as successful therapeutic agents. Injection of such antibodies leads to a decrease in viral concentrations in blood. However, repeated injections are necessary to prevent the recovery of the virus.
