Versalinx Kits HRP and AP, GeneLinker Gold, Phoretix Array Database v2.0, BRB-ArrayTools Version 2.0


Prolinx of Bothell, Wash., has released two new products for protein detection, Versalinx rapid protein-enzyme conjugation Kits HRP and AP. Versalinx chemical affinity technology utilizes the specific interaction between molecules containing P(D)BA (phenyl(di)boronic acid) and SHA (salicylhydroxamic acid) to link or attach nucleic acids, proteins, and other macromolecules for use in analytical and preparative assays. The new detection products use the Versalinx complex to attach an enzyme molecule (horseradish peroxidase or alkaline phosphatase) to any protein probe. Prolinx recently introduced its Versalinx chip kits, based on the same chemistry.


Molecular Mining Corporation of Raleigh, N.C., has released version 2.0 of its gene expression analysis software GeneLinker Gold. In addition to improved speed and data handling, new features include 3-dimensional principal component analysis plots, summary statistics and profile matching. They complement the existing self organizing maps (SOMs) and Jarvis-Patrick clustering (also known as mutual nearest neighbors).

Nonlinear Dynamics of Newcastle upon Tyne, UK, has released Phoretix Array Database v2.0., to be used with the recently upgraded Phoretix Array v3.0. The new database version introduces a data mining wizard allowing improved statistical capabilities, including principal component analysis, multidimensional scaling and correspondence analysis. It also has a reworked interface.


BRB-ArrayTools Version 2.0 will be available from the National Cancer Institute next week at http://linus. It will include a global test of clustering in PCA space. The software is free of charge to academic and non-profit institutions; companies can license it.
