ADC Antibody Screening Service
Fig.1 Structure of ADC.To avoid the severe side-effects due to lack of target specificity caused by conventional cancer therapies such as chemotherapy, radiation therapy and surgery, Creative Biolabs is dedicated to targeted therapies, especially antibody-drug conjugates (ADC) that can improve the safety and efficacy to treat cancer. We have exploited a comprehensive ADC platform including ADC antibody screening, conjugation chemistry, linker and payload service, analytical characterization and validation, fill and finish, etc. to facilitate your ADC discovery and development.
ADC Antibody Screening Services
With the toxic payload linked to a monoclonal antibody that is specific for target antigen, ACD can specifically deliver the toxic payload into the target tumor cells which can ideally eliminate the payload toxicity to healthy tissues. Most of the toxic payloads play the functional role by disrupting important cellular pathway, hence, antibody internalization is critically important for good ADC efficacy through receptor mediated endocytosis.
☆ Tumor Antigen Identification
Creative Biolabs offers the ADC antibody screening service to help you identify the appropriate tumor antigen as per the following stringent criteria.
-
To allow efficient ADC binding, the antigen should be in appropriate cell surface localization;
-
To ensure high specificity and efficacy, the antigen should be specific for tumors rather than healthy tissues;
-
If no tumor specific antigen is identified, the antigen with much higher expression compared to that in normal tissues can be considered;
-
To ensure ADC incorporation through receptor mediated endocytosis when ADC binding, internalization of antigen should be considered.

☆ Antibody Screening
Once the tumor antigen is identified, Creative Biolabs offers antibody extensive screening to get a few suitable monoclonal antibodies with specific target recognition capability for ADC development.
-
With extensive experience and advanced antibody libraries, we offer well-established phage display platform to our clients for antibody screening with high antigen specificity and binding affinity;
-
We offer a series of antibody engineering services such as antibody humanization service to engraft the appropriate CDR regions into the suitable human framework for ADC development;
-
Except for high specificity and binding affinity, a strong tendency for internalization is a must for a successful ADC once binding to an antigen. We offer unique internalizing antibody screening services to screen for ‘internalizing’ antibodies through pH-sensitive dye, fluorescent labeling, etc.
☆ Anti-Ab ADC
We also offer a unique Anti-Ab ADC service to evaluate the internalization abilities of targeted antibodies via assessing the toxic effects generated by Anti-Ab ADC. We aim to select the best ADC antibodies for your project.
