The Hitachi Software MiraiBio Group has just released a new build of MasterPlex QT v4.0 that boasts several new improvements:

• Best Fit Options – The Best Fit feature now offers 3 parameters for which you can optimize for to determine the best curve fit:
  1. Root Mean Square Error (RMSE) – RMSE is a good measure of accuracy or goodness of fit which aggregates the individual differences or residuals between your expected and calculated values into a single measure of predictive power. This is the default option as it is the one that is recommended.
  2. Standard Deviation of % Recovery – This option will provide the model equation and weighting algorithm combination with the lowest standard deviation of percent recovery. The percent recovery is basically the calculated concentration – the expected concentration * 100.
  3. R-squared – This option is the only Best Fit option in previous builds of MasterPlex QT v4.0. It is not as sensitive to the goodness of fit as the RMSE option.

  

• Competitive Binding and Inhibition Assays – This build provides improved support for competitive binding or inhibition assays.

  

• More Intuitive Auto Fill – Auto Fill is simplified with more intuitive dilution direction buttons and being able to preview the standard values.

Add value to your Bio-Plex® system with the MasterPlex software suite:

• MasterPlex QT v4.0 – Curve-fitting quantitative analysis software
• MasterPlex EX – miRNA and Gene Expression analysis software

Many Bio-Plex owners may not be aware of this but the new MasterPlex platform is fully compatible with the raw data files that can be exported with the Bio-Plex Manager software.

To obtain the raw data file from the BioPlex Manager software:

1. Locate the original RBX file and open it with BioPlex Manager
2. Make sure you are viewing the Raw Data table
3. In the top row of icons, there is an Export to Excel icon. This icon may be in a different position depending on the version of the software. This function will export the raw data into an Excel .xls file that is compatible with MasterPlex.
4. Simply use the Open file function in the MasterPlex software and browse to the .xls file and that is it!
