블로그 약 Lexogen Launches Highthroughput Sequencing Kit for Faster Library Prep

In the fast-paced world of life sciences research, where experimental precision directly determines success, PCR cycle optimization has long presented a critical challenge for researchers. The reliability of high-throughput sequencing data - the cornerstone of modern biological research - fundamentally depends on the quality of library preparation, with PCR amplification serving as its pivotal step.

Researchers frequently face a persistent dilemma when determining optimal PCR cycles. Undercycling results in insufficient library yields, particularly problematic with limited samples or low-abundance targets, potentially causing critical data loss. Conversely, overcycling introduces nonspecific products and artifacts that distort gene expression profiles, potentially leading to erroneous conclusions.

This delicate balance between amplification efficiency and fidelity has traditionally required extensive trial-and-error approaches, consuming valuable time and resources while delivering inconsistent results.

Addressing these industry-wide challenges, Lexogen introduces its groundbreaking PCR Add-on and Reamplification Kit V2 , designed to bring unprecedented precision to cDNA library preparation for QuantSeq V2, QuantSeq-Pool, and CORALL V2 systems.

The kit's revolutionary qPCR detection capability, utilizing SYBR Green I dye, enables real-time monitoring of amplification kinetics. This allows researchers to:

• Determine endpoint PCR cycle numbers with scientific precision
• Eliminate guesswork and empirical estimations
• Prevent both underamplification and overamplification artifacts

The optimized PCR mix includes high-fidelity polymerase and Illumina-compatible primers (without barcodes), supporting up to 96 qPCR reactions per kit. Notably, this qPCR function is specifically designed for current-generation Lexogen products and not recommended for earlier QuantSeq or CORALL versions.

Beyond cycle optimization, the kit features a specialized reamplification (RE) primer system that:

• Boosts library yields when initial amplification proves insufficient
• Enhances detection of low-abundance transcripts
• Supports enrichment panel applications

This reamplification function maintains compatibility across Lexogen's entire product line, including all CORALL and QuantSeq versions, LUTHOR preparations, and small RNA-Seq libraries.

The dual-function kit provides:

• 96 qPCR reactions for cycle optimization
• 96 reamplification reactions for yield enhancement

Compatibility includes:

• CORALL RNA-Seq V2 with UDI (Cat. 171-186)
• QuantSeq V2 with UDI (Cat. 191-196)
• QuantSeq-Pool (Cat. 139)

The kit is specifically incompatible with TeloPrime (Cat. 013) products.

Lexogen's V2 kit represents a significant leap forward in library preparation technology, offering researchers:

• Data-driven PCR cycle determination
• Flexible yield enhancement options
• Streamlined workflow compatibility
• Illumina platform readiness

By eliminating traditional PCR optimization challenges, this innovation allows scientists to focus on biological discovery rather than technical optimization, potentially accelerating breakthroughs in gene expression analysis and transcriptomics research.
