High Throughput SequencingINQUIRY
In order to address the drawbacks of DNA-encoded library selection such as non-specific binding of compounds, lower enrichment factors, a large numbers of false positive compounds, etc. DNA amplification and sequencing methods are applied to provide a selection approach with higher stringency.
Principle of High Throughput Sequencing
The interaction between DNA-tagged target proteins and small molecules can lead to DNA hybridization and formation of a hairpin structure. The structure then encodes the binding molecule and the target protein after primer extension and DNA-amplification. The interaction-dependent PCR (IDPCR) has the potential to detect ligand-target interactions of varying affinities in a multiplexed format and the binding of DNA-tagged target proteins and DNA small molecule conjugates can be evaluated successfully.
Process of High Throughput Sequencing
The whole process of DNA amplification and sequencing can be seen as a solution-based incubation method, in which the molecule of interest is added into and only the DNA barcodes that are attached to bound chemicals are allowed to be amplified. In this process, protein-oligonucleotide conjugates act as a primer for bound molecules and stabilize the DNA heteroduplex formation and facilitates the initiation of a PCR amplification process.
