21 CFR Part 11 is the United States Food and Drug Administration's (FDA) requirement for electronic record keeping. These are the rules under which an electronic document can be considered equivalent to a paper document. In part, this includes software validation, password protection of data and macros, time-stamped audit trail capability, and various password and security measures.
SigmaPlot already satisfies the requirement for in-house validation using a test suite containing over 1400 scripts. Also the macro language provides the mechanism for repeatable "hands-off" analysis of instrumentation data.
As part of an incremental plan for implementing Part 11, SigmaPlot 8.0 has the capability of reading MS Access databases. This is the beginning of an interaction with database technology that will allow implementation of important security and audit trail requirements.
The remaining requirements will be added in subsequent SigmaPlot releases. We are working with our customers to design and implement these features so that their needs are satisfied.

Cut and paste data from any application or enter your data manually. The module allows you to select the units of your velocity or other dependent variable values from a drop down list. These units are carried to the worksheet and to the final graphs. Replicate velocities may be entered, and for inhibition studies, you can choose to vary either the substrate or the inhibitor concentrations for each series. Select from lists of unit values for substrate and velocity or enter your own; the units are carried through to the reports and graphs. And once you run your analysis, organize your reports, graphs and equations in the SigmaPlot Notebook.
Select From a Wide Range of Built-In Models
| Select from multiple equation groups to analyze your data. The module provides about 40 different built-in equations to characterize different types of reaction mechanisms. It automatically estimates the initial parameters for the selected model(s), and uses the Marquardt-Levenberg algorithm to determine the parameter values. You get a detailed statistical report as well as a data report that includes the Km, Ki and Vmax values and their standard errors. You can simultaneously fit and compare multiple models and graphs from library of built-in equations. You can also enter your own custom equations and save them for future use. |
 |
Easily Determine the Best-Fit Inhibition Model for Your Data
| To compare the different inhibition models, the Enzyme Kinetics Module provides a detailed report with complete statistical analysis for each model, as well as provides information on comparing the different models. Several goodness of fit criteria including Akaike's AIC are provided to determine the best model. Statistical results include parameter value confidence intervals, a residual runs test and outlier detection. The data report includes replicate mean velocities and their standard errors, the predicted and residual values from the curve fit and an indication of data outliers. The statistical report generated for each model includes the parameter values with their standard errors and 95% confidence intervals, Akaike, R2, sum of squares, standard error of the regression, and the significance level for the runs test. The selected models can be automatically ranked by goodness of fit. |
 |
See Results Clearly With Interactive Graphs
| You can create any one or all of the built-in graphs provided for each study. The module automatically generates interactive graphs you choose to display your results. You can modify the graphs as desired to present your results exactly the way you want to using SigmaPlot's ability to customize your graphs. Many of the graph algorithms automatically determine where fit lines intersect the axes and present the graphs in this manner. To help determine the type of inhibition, the curve fit lines are designed to allow you to extend the graph axes to show fit line intersection. |
