The Background of Organic Molecules as Substrates of Phage Display
Small organic molecules target for phage display is more challenging than synthetic or natural polymers. In some cases, small organic molecules can be directly used as substrates for phage display in form of solid crystals. In many other cases, however, the molecules are immobilized on spherical beads or on planar substrates. Small organic molecules like fluorophores, including Texas Red, Oregon Green 514 and fluorescein, were first used as targets for phage selection. Some research groups have demonstrated the feasibility of using peptides identified by phage display for the selective detection of explosives molecules, such as 1,3,5-trinitrobenzene (TNB), 2,4-dinitrotoluene (DNT) and 2,4,6-trinitrotoluene (TNT). Besides above, phage display has also been utilized for the identification of organic molecule binding peptides for potential sensing applications or surface patterning. Octyltrimethoxysilane (OTMS) binders have been used for patterning OTMS-containing silicon surfaces via microcontact printing or photolithography. Peptides have also been identified for selective recognition of two different polychlorinated biphenyl’s (PCB’s), which are known to be carcinogenic and can accumulate in tissue.

Creative Biolabs has developed a variety of strategies to identify peptides that can selectively bind to different small organic molecules. Numbers of sub-libraries with extra mutagenesis of the identified phage clones can be constructed for further selection of clones with higher affinity than the originally selected ones.
