SMCxPRO Immunoassay System: Sensitivity You Can Count On
Your research demands flexibility to move from platform to platform and assay to assay. Using single molecule counting (SMC™) technology, MilliporeSigma offers you the ability to take the analysis of your protein of interest down to femtogram/mL levels using the ultrasensitive protein detection SMCxPRO™ platform. This improved level of sensitivity allows for previously undetectable proteins to now be quantified, including endogenous levels.
TechTalk: Pioneering LFA sensitivity and versatility for better diagnostics
Friday, May 15 at 16:00 BST | 17:00 CEST | 11:00 EDT | 8:00 PDT
In lateral flow diagnostics, improving assay performance is essential for better outcomes. In this 20-minute SelectScience® TechTalk, held in partnership with Merck, we will highlight how optimizing sample handling and key raw materials can significantly improve signal quality and assay consistency.
This expert talk will use real-world case studies to demonstrate advancements in reliable and versatile at-home testing solutions. These innovations illustrate how improved sensitivity and stability make diagnostics more accessible and effective, for better healthcare outcomes for everyone.
This TechTalk is part six of a seven-part expert-led TechTalk series on essential topics in LFA development. Register to watch live or on demand and receive exclusive invitations to upcoming sessions.
