Team:BostonU/Clotho

Our project is focused on creating a standardized method for the characterization of genetic circuits in synthetic biology. In order to achieve this goal, it is necessary to have a platform that enables us to create the standardized data, organize it and manage it efficiently. Clotho is a great synthetic biology tool that has been helping us with exactly that!

This section aims to describe how we have been using Clotho in our project. We divided the content into the Clotho Apps we used, giving a brief explanation of how each App works and examples of situations in which they were useful for our project. We hope you can all get good ideas on how to use Clotho on your projects and take advantage of this amazing tool!

SpreadIt Oligos is an app that allows users to browse and input oligos from and into the data base. We used this app to add on additional oligos one at a time aside from spreadsheets of primers that were added by Bull Trowell. SpreadIt Oligos does what Bull Trowell does on a smaller scale.

Bull Trowel is a very useful app for adding large amounts of Parts, Oligos, Vectors, Plasmids and etc from an excel sheet to Clotho`s inventory. In our case, we had a list of almost 200 primers that we designed in an Excel sheet that we wanted to include in our inventory. All of them could be added much faster and with lower mistake rate by using Bull Trowel. Below, there is an example of the interface of the app while we were adding our oligos and the Excel sheet from which we took the oligo sequences.

Also, the description section helps to give meaning to the nickname and makes the inventory more user-friendly.

Sequence Viewer is a very useful app to analyze sequences that are in the inventory . It allows us not only to view the sequences of DNA, but also to interact with it by highlighting specific portions that we are interested in. For example, we used sequence viewer to find and highlight restriction and fusion sites within the sequence.

SpreadIt Features was a very useful tool while we were designing our MoClo primers. When we create primers for moclo, we need to make sure the genes for which we create the primers do not have certain restriction sites within them where our moclo enzymes will cut. We thus use the spreadit feature app to create features such as restriction sites by entering the sequence into the data base so that when viewing the gene sequence in sequence viewer, we can look for these restriction sites. Also, SpreadIt Features enabled us to create MoClo fusion sites as features to be analyzed in our sequences so we can better predict how and where ligation in MoClo reaction is occurring.
