DNA Assembly

Why Construct Assembly with Synthace?

The advancement of DNA assembly is changing many fields of biotechnology, from vaccines to biomaterials. Highly efficient methods require automation that can keep up with the higher throughput. As construct assemblies utilize more parts, the number of possible outcomes increases and the throughput increases, necessitating automation. Programming devices for these processes can be a challenge, especially for complex assemblies requiring multiple parts.

Robust, reproducible designs

Synthace simplifies performing complex assemblies by automatically programming liquid handling steps, liquid transfer calculations, and providing full sample traceability.

Protocol walkthrough

Basic concepts

Translate human-readable actions into machine instructions

Simple building blocks...

Elements are a key concept in Synthace. They translate human-readable actions into machine instructions. You can define how the experiment will be performed through the element input parameters.

Elements form the visual user interface to Synthace’s planning engine. Synthace interprets your requirements and translates these into complex robot instructions. Input volumes are also calculated and the labware needed is determined.

...translated into complex robot instructions

You can create workflows in Synthace by connecting elements together to specify the flow of physical materials and information.

A simple workflow example is connecting an element where liquids and their properties are defined (e.g. liquid names, concentrations, pH, and so on) with an element that aliquots these liquids onto a plate as desired.

Define experiment

Easily define and modify your experiment

Define your assemblies to automate the design

Synthace’s device-agnostic software automatically converts assembly design into instructions for any device you are using

Overview of entire experiment

Synthace’s Execution Details page aggregates plate layouts, labware and reagents required, Assembly Report and a full set of device-specific instructions

Preview in silico

Preview your runs in detail at your desk

Synthace’s execution preview shows a layout of your device, and clearly shows where labware needs to be placed and the amount and location of your reagents.

The preview also shows every liquid handling action in order of execution with a useful step-by-step time estimate. This minimizes the chances of errors, and gives you an immediate estimate of walk-away time. Hovering over individual transfers will indicate the selected liquid handling policies. 


Keep track of your assemblies

Presents the required labware

Synthace’s Assembly Report automatically keeps track of the parts and lengths of your assembly as well as calculates your assembly's fidelity without the need for additional software. This increases the assembly's robustness and reproducibility. Keeping all experimental files and reports on one page reduces manual data matching which can be slow and error-prone. 

Introducing Synthace, the world’s most powerful software platform for performing biological experiments

​​Intelligent software for the dynamic use of laboratory automation

Sophisticated experiments made simple


Synthace for DNA Assembly is available on:

  • Tecan's Freedom EVO®
  • Hamilton's Microlab® STAR and STARlet
  • Gilson's PIPETMAX®

The Synthace planning engine parses the high-level inputs specified in your workflow, including the experimental design, selected labware and deck layout. The planning engine converts these instructions into low-level instructions such as the liquid handling steps and the exact labware positions on your predefined deck layout.

Yes, custom deck layouts can be chosen in Synthace. The user can define multiple deck configurations for the same liquid handler mode.

SynthaceHub automatically sends log and configuration files to the cloud for storage in your organization’s private data repository in Synthace from the liquid handler’s native software.

Although calendar integrations are not yet available in Synthace, the estimated run times as calculated by Synthace’s planning engine provide an accurate timing for you to ensure that you have booked enough time on your desired devices to execute your experiments.

Synthace will work out the changes necessary to implement your workflow. You simply need to upload your deck configuration and re-simulate — Synthace will use your new worktable layout to determine the necessary instructions.

Synthace comes with its own library of different liquid handling policies for all types of liquids. You can select different liquid handling policies for each of the liquid handling steps. Different samples can have different policies, and these policies can be linked to your liquid classes on certain liquid handling devices.

Yes, Synthace’s cherry picker is one example of that. Another example would be DOE runs with hard to change factors where we would need to run across two workflows.

Experimental results can be searched and accessed by everyone in your group/organization who has an account in Synthace. If you would like to discuss access control and data security in more detail, please drop us an email or use the “Request a demo” button above.
