blog about Applied Biosystems CLA Globalfiler Boosts Cell Line Authentication Efficiency

Researchers worldwide have long struggled with the time-consuming and complex process of cell line authentication. The constant concern about sample cross-contamination or misidentification has been a persistent challenge that could compromise the accuracy of painstaking research results. A groundbreaking solution has now emerged: the Applied Biosystems™ CLA GlobalFiler™ PCR Amplification Kit.

This innovative kit transforms the traditionally cumbersome, error-prone cell line authentication process into an efficient, precise, and reliable short tandem repeat (STR) analysis workflow, significantly enhancing laboratory operational efficiency.

The CLA GlobalFiler™ Kit represents more than just another reagent solution—it's an advanced analytical tool integrating six fluorescent dyes capable of covering an impressive 24 STR loci. Its core strength lies in exceptional global data compatibility, ensuring seamless integration with any major international cell line database standard.

• Multiplex Fluorescence Labeling and Comprehensive STR Coverage: The kit's ability to simultaneously analyze 24 critical STR loci using six precise fluorescent dyes provides exponential information growth, significantly enhancing genotype differentiation accuracy.
• Global Data Compatibility: Designed with international research collaboration in mind, the kit ensures maximum compatibility with current and future database standards, facilitating cross-laboratory and cross-regional data sharing.
• Optimized Amplification Time and Superior Resolution: Proprietary reagent formulations and reaction conditions dramatically reduce PCR amplification time while maintaining exceptional differentiation capability, even for complex samples.
• Integrated Solution: The inclusion of GeneScan 600 LIZ® Size Standard v2.0 eliminates the need for separate size standard optimization, streamlining experimental workflows.
• Broad Instrument Compatibility: The kit works seamlessly with multiple Applied Biosystems genetic analyzers, including SeqStudio, 3730/xL, 3500/xL, and SeqStudio Flex models, protecting existing laboratory investments.

The CLA GlobalFiler™ Kit demonstrates exceptional value in two critical areas:

Human Sample Authentication (HSA): In life sciences research and biopharmaceutical production, STR analysis provides rapid, accurate verification of cell line DNA profiles, effectively detecting and preventing sample contamination or misidentification.

Mixed Sample Analysis (MSA): For complex samples containing multiple DNA sources—such as in chimerism studies—the kit enables precise identification of contributing genotypes, proving invaluable for hematopoietic stem cell transplantation monitoring and tumor microenvironment research.

The kit includes the GlobalFiler™ PCR Amplification Kit and GS LIZ 600 Size Standard, utilizing gel electrophoresis for stable, accurate results. Its liquid formulation offers ready-to-use convenience, while high GC content PCR performance ensures effective amplification of complex genomic regions.
