UMI Second Strand Synthesis Module for QuantSeq FWD – July 2025
Dear Customer,
Thank you for choosing Lexogen’s UMI Second Strand Synthesis Module for QuantSeq FWD (Catalog Number 081). We are committed to delivering high-quality products and maintaining transparency with our customers.
We are writing to inform you of a minor observation in recent batches (B081010, B081011, and B081012) of this module. Our quality control processes identified a slight enrichment of guanines following the UMI TATA spacer sequence. This variation stems from the inherent properties of the random second strand synthesis primer, where minor batch-to-batch differences may occur.
Please be assured that the reproducibility within each batch remains excellent, and this observation does not impact the performance of single-experiment applications. For experiments comparing results across different batches, you may notice minor variations in transcript detection.
If you have any questions or require further assistance, our dedicated support team is here to help. Please contact us at support@lexogen.com, and we will be happy to discuss your specific needs or provide additional guidance.
Thank you for your continued trust in Lexogen. We value your partnership and are committed to supporting your research!
Sincerely,
Lexogen’s Customer Care Team
