Ab-origin: An Improved Tool of Heavy Chain Rearrangement Analysis for Human Immunoglobulin [chapter]

Xiaojing Wang, Wu Wei, SiYuan Zheng, Z. W. Cao, Yixue Li
2007 Lecture Notes in Computer Science  
An improved tool to explore the origin of human immunoglobulin heavy chains, named Ab-origin, has been developed.  ...  Though only taking the human heavy chain for an example here, the algorithm also suits for the analysis of all immunoglobulin and TCR sequences.  ...  technology commission of Shanghai municipality (04DZ19850, 06PJ14072).  ...

Clustering-based identification of clonally-related immunoglobulin gene sequence sets

Zhiliang Chen, Andrew M Collins, Yan Wang, Bruno A Gaëta
2010 Immunome Research  
Results: We have developed and implemented an algorithm for identifying sets of clonally-related sequences in large human immunoglobulin heavy chain gene variable region sequence sets.  ...  The identification of groups of rearranged immunoglobulin gene sequences descended from the same rearrangement (clonally-related sets) in very large sets of sequences is facilitated by the availability  ...  Acknowledgements The authors thank Michael Bain and Katherine Jackson for helpful comments and feedback. This article has been published as part of Immunome Research  ...

Multispecificity of a recombinant anti-ras monoclonal antibody

John W. Schrader, Gary R. McLean
2017 Journal of Molecular Recognition  
Whilst studying the cellular molecular switch protein m-ras, a recombinant monoclonal antibody to m-ras was generated for use as a research tool.  ...  The cross reactive binding of the monoclonal Ab to h-ras was defined by peptide array blot revealing that the Ab showed preference for peptide sequences containing multiple positively charged amino acid  ...  Conflicts of Interests: The authors declare they have no conflicts of interests.  ...
