<strong>magic</strong> <strong>phage</strong><br />
• Aiming at facilitating the progress of next-generation antibody therapies, Creative<br />
Biolabs has integrated multiple state-of-the-art technologies and resources<br />
during the past decades. We are proud to introduce our featured Magic Human<br />
Antibody Discovery Platform to our worldwide customers. In particular, we<br />
combine the genetically “humanized” mice with our strong expertise in <strong>phage</strong><br />
display immune library technology, offering a powerful approach for the<br />
discovery of high specific, high-affinity antibody candidates.<br />
• Phage display library construction and library screening has long been one of the<br />
most widely used methods for antibody generation towards a variety of targets.<br />
Conventional hybridoma technology may lose many potential binders during cell<br />
fusion and screening process. In contrast, by creating a huge pool representing<br />
the entire antibody repertoire, <strong>phage</strong> display technology allows the collection of<br />
the whole set of antibodies in immunized animals, and subsequent isolation of<br />
the best binders from the collection. Moreover, enriching steps and counter<br />
selections can be easily incorporated in panning steps. Nowadays, it is<br />
contributing to various biomedical research and industrial applications.
• Despite these appealing strengths of <strong>phage</strong> display technique, it is largely<br />
restricted by immunization host - obviously one cannot immunize a human<br />
for antibody development. In this regard, transgenic mice can offer a<br />
promising solution. Transgenic mice, or “humanized” mice, have emerged<br />
as one powerful toolbox for not only antibody development but also<br />
pharmacokinetic/immunogenicity studies, and so on. They are constructed<br />
through introducing human Ig transloci into mouse germline and silencing<br />
endogenous mouse Ig gene at the same time. This way, these engineered<br />
mice can then produce fully human antibodies. Creative Biolabs has<br />
integrated several first-class transgenic mouse strains with diverse genetic<br />
background, as well as different capacities to generate both normal (heavy<br />
and light chain) antibodies and human sdAbs (heavy chain only). The<br />
resulting antibody candidates can provide following advantages compared<br />
to alternative methods:
• More robust discovery<br />
• Optimal affinity, specificity, developability, and other properties (in<br />
vivo selection)<br />
• Fully human nature<br />
• More potent functionalities<br />
•<br />
In combination, <strong>phage</strong> display immune library technique can make the best<br />
of the humanized mice for the discovery of ideal antibody binders against a<br />
given target. We can obtain the entire antibody repertoire as a<br />
comprehensive library, and perform high-throughput biopanning to get<br />
high-affinity binders.
• As alternatives, Creative Biolabs also offers transgenic mouse/rat<br />
hybridoma and Native plasma cell sorting strategies which can also<br />
incorporate with transgenic mice for antibody development. Our<br />
experienced scientists are always willing to discuss with every<br />
customer on a case-to-case basis. Please feel free to inquiry us for<br />
