Phage display technology is one of the major approaches employed in various protein interaction studies,<br />
especially in the discovery of specific antibodies, scaffolds or ligands. While binders with the desired<br />
specificity generally exist at low frequencies in the constructed libraries. In this way, phage display <strong>library</strong><br />
<strong>screening</strong> has become an effective technique for the enrichment and identification of binders with high<br />
affinity and specificity from interested libraries.<br />
• At Creative Biolabs, the proprietary protocol and tailored biopanning strategy allow the increase of<br />
candidates with higher affinity and desired specificity (e.g. binders recognize conformational epitope rather<br />
than linear epitope). In general, by conducting four rounds <strong>library</strong> <strong>screening</strong>, our scientists can select<br />
scFv/Fab antibodies with the affinity of 10 -7 . Through constructing serial sub-libraries of the isolated<br />
scFv/Fab antibodies, we can increase the affinity from 10 -8 to 10 -9 . Moreover, Creative Biolabs has<br />
successfully obtained a scFv <strong>antibody</strong> with an extremely high affinity of 10 -12 .<br />
• Based on our standard biopanning protocol, Creative Biolabs can utilize different strategies for <strong>library</strong><br />
<strong>screening</strong> to meet our clients’ project goals.
Solid-Phase Screening : the most straightforward and widely used way to select binders against interested target adsorbed onto a solid surface. Typically, the targets can be coated on the well of i<br />
Solution-Sorting Screening: an ideal approach to isolate binders recognize naïve targets. The target-binder interaction is carried out in solution with subsequent capture by the appropriate method<br />
Cell-Based Screening: a method in particular for cell surface antigen selection. It is a reliable approach to screen cell surface antigens with native conformation, especially when the antigen is hard<br />
In vivo Screening: a high throughput method for efficiently isolating tissue-specific binders. The selection is based on binding to target in vivo after the injection of interested phage libraries into who<br />
Ex vivo Screening: a novel technique to employ primary cell suspensions of organs and tissues as targets. All cell types can be exposed for selection to identify the most specific binders.
