Efficient, streamlined production workflows at SignaGen enable the delivery of high-titer lentiviral vectors typically within approximately four weeks from lentivector cloning to final vector shipment. This accelerated turnaround is achieved through parallelized lentivector design, cloning and verification workflows, optimized transfection and cell culture conditions, and rapid downstream purification and quality control processes—without compromising vector quality or performance. For time-sensitive projects, an expedited production option is available in which lentiviral packaging is initiated on Friday followed by early harvest on Monday, allowing vector production to be completed in as little as three weeks. This flexible scheduling supports urgent research timelines while maintaining consistent standards for vector yield, purity, and transduction efficiency.
