When combined with the Version 4 Sequencing Kit which was launched in September 2025, the Company expects users will see significant improvements analyzing scarce biologic samples, complex mixtures, and detecting low abundance biomarkers.","length":614,"tagName":"p"},{"type":"text","content":"The Version 3 Library Preparation Kit is a significant improvement over the current kit and requires 200 ng or less of total protein input. This represents a 100-fold improvement over the current kit. Furthermore, data from internal validation studies demonstrates that the Version 3 Library Preparation Kit enables detection of proteins in mixtures with as little as 1-2 ng of protein which equates to less than 1% relative abundance in a sample mixture. These capabilities will greatly increase the ability for users to process scarce biologic samples and detect low abundance proteins in applications such as signaling pathways.","length":631,"tagName":"p"},{"type":"text","c...
