ImmunoCompliance™ ELISPOT


CTL, as the leader in ELISPOT technology, has carefully elevated its products and solutions onto a platform that permits this T cell assay to take place within an environment ready to fulfill the requirements from Part 11. CTL has combined instrumentation and software with a powerful "Part 11 framework."

Features include:

Secure data storage

Audit trails

Record retention management

Access control

Data integrity

To facilitate GLP regulated workflow, CTL offers ImmunoCompliance. The ImmunoCompliance™ package consists of CTL’s ImmunoQuality™ package and CTL’s ImmunoData™ Storage Software and includes the following components:

ImmunoSpot® Analyzer

CTL’s ImmunoSpot® Analyzers have integrated a variety of features to meet regulatory requirements including an encoder controlled device check of the data source verifying well positions during acquisition, a barcode reader permitting the verification of the plate alignment, and a Redundant Array of Inexpensive Discs (RAID) system supporting data recovery.

ImmunoSpot® ImmunoCapture™

ImmunoSpot® ImmunoCapture is a login controlled application that stores data directly into the ImmunoData Storage Software where all files are assigned an object type with attributes for further record control such as retrieval and subsequent processing. The application also creates a log file recording data entries made during automated routine operation.

ImmunoSpot® Counting

Counting results are filed separately from the raw data in order not to alter or obscure the originally captured images. Spot count is noted beside each well image and any changes in spot count are highlighted in red and recorded in the data. All data delivered in Excel®, text, or other formats is monitored for possible changes. Audit trails are automatically generated for each data file.

ImmunoSpot® Quality Control

In the quality control step, the user makes the ultimate judgment of the quality of the results, i.e., subtraction of artifact. The software permits the capture of annotations for each well indicating what and why changes were made.

ImmunoQualify™ Software

ImmunoQualify™ is a software tool that permits the qualification of the reader’s status on a regular and repeating basis. It automatically compares CTL’s artificial reference plate with the actual reference value that is unique for each device.

ImmunoQuality™ Package

CTL’s ImmunoQuality™ Package can also be purchased separately. ImmunoQuality™ is a hardware and software package with GLP compliant features including the ImmunoQualify™ software, ImmunoSpot® Professional Software, Instrument qualification reference plate, integrated barcode reader, user authentication, ELISPOT data security, and RAID system for data backup and recovery.
