Library Results

Overview

Overview

We implement a basic diversity of initial binding proteins by creating a high-quality library consisting of over one hundred thousand monobodies and over onehundretsixty thousand Nanobodies. By this we set up the foundation to build our system on and set a cornerstone for utilizing and generating libraries in iGEM.

We verified the functionality of our library by several approaches.


Assembly

We did not just show that our design and construction of our libraries was successful we also adapted the way to assemble them. By that we established an unprecedented approach in this competition and provide future iGEM teams a great part collection to build their own libraries.

Phagemid Display

We could show that our libraries consists of several initial binders in even small extracts. Thus, the Evobody can get in the directed evolution and can be optimized by mutation and selection.

Sequencing

Sanger sequencing was applied to check the correctness of assemblies and to examine the appearance of the different chosen bases for positions of the variable regions of our binding proteins, respectively. Also we calculated the actual library sizes by high-throughput sequencing technologies.
