Patent number: 9164022Abstract: The present invention provides automatic gating methods that are useful to gate populations of interest in multidimensional data, wherein the populations of interest are only a subset of the populations identifiable in the data. The populations are modeled as a finite mixture of multivariate probability distributions, preferably normal or t distributions. The distribution parameters that provide a best fit of the model distribution to the data are estimated using an Expectation Maximization (EM) algorithm that further includes a dynamic neighborhood thresholding that enables gating of a subset of the clusters present in the data.Type: GrantFiled: February 12, 2015Date of Patent: October 20, 2015Assignee: Becton, Dickinson and CompanyInventors: Yuanxin Zhu, Mengxiang Tang

Publication number: 20090011440Abstract: The invention provides a method for determining the activation status of receptor tyrosine kinase (RTK) pathways in either cell samples or patient samples by measuring receptor dimerization and relative amounts of protein-protein complexes or activated effector proteins that are characteristic of an RTK pathway. The invention also provides a method of using such status information to select patients responsive to pathway-specific drugs, and more particularly, to methods for measuring ErbB receptors and receptor complexes and using such information to select patients responsive to ErbB pathway-specific drugs. Preferably, methods of the invention are implemented by using sets of binding compounds having releasable molecular tags that are specific for multiple components of one or more complexes formed in RTK activation. After binding, molecular tags are released and separated from the assay mixture for analysis.Type: ApplicationFiled: July 21, 2008Publication date: January 8, 2009Applicant: MONOGRAM BIOSCIENCES, INC.Inventors: Ali Mukherjee, Mengxiang Tang, Harprit S.
