The HELM Antibody Editor allows the user to visualise and manipulate antibody structures.

 It It includes many features, but the ability to detect domains and add structural features such as Cys-Cys bonds is central.


 **New** HAbE2

HAbE2 is now available in GitHubwas released to GitHub in January 2018. Many thanks again to Roche who have continued to develop the antibody editor and have donated their efforts to the open source community.

Key new features include:  

Info

MonomerDesigner
Design your own new monomer for the HAbE and save it into your local monomer store

ADCDesigner
Attach chemical molecules to a peptide at the N- or C-terminal end, on specific amino acids or on an amino acid type with a statistical binding ratio
 

Domain Protease Reaction
Cut your antibody according to the protease sequence motif

Sortase Coupling
Split your antibody according to a peptide motif and connect it with a ligand

Biotinylation
Covalently attach biotin to AVI-tag

HELM is an open source project released under the MIT license. However it HAbE2 currently has some dependencies one dependency on third party tools.

  • HELM Editor HAbE2 requires yFiles for Java version 2.6 or higher and GraphML extension from yWorks. If you wish to use the compiled software directly there is no need to buy a licence. If you wish to develop the software for your own use, trial versions of such libraries can be downloaded from yWorks at www.yworks.com. You need to update the ant build file with regard to yfiles.dir and jar file names before compiling and running the project.
  • The HELM Toolkit requires MarvinBeans version 5.0 or higher from ChemAxon. A copy of the required library (MarvinBeans-5.0.jar) is included for your convenience. ChemAxon has graciously agreed to provide a royalty-free license for the utilization of MarvinBeans directly through the HELM editor and notation toolkit (specifically for operations pertaining to the chemical representation of HELM monomers and macromolecules.) Please contact Cassell Essell (cessell@chemaxon.com) to obtain this license. Utilization of the MarvinBeans library outside of the aforementioned scope and beyond a trial basis requires the procurement of a regular MarvinBeans license.
