The NGP System delivers AST results in hours for both isolated colonies and positive blood cultures, following three FDA 510(k) clearances, including one for the direct from Positive Blood Culture Separator earlier in 2024. On April 1, 2024, Selux announced an additional $48 million in funding led by RA Capital Management, with participation from Northpond Ventures, Sands Capital, and Schooner Capital, to support the next phase of commercialization of the NGP System in the United States. This round brings the company's total funding to $112.6 million, following prior raises including a $50 million Series C in February 2022 and a $14.6 million round in June 2021. The funding coincides with the company's advancements in FDA-cleared components like the Positive Blood Culture Separator, Inoculator, Analyzer, and Gram Negative and Gram Positive Panels. Selux positions its technology as transformative for patient care, aiming to save lives, shorten hospital stays, and reduce overuse of broad-spectrum antibiotics. |

Prior to the Series C, the company raised $25 million in Series B and received a $2.8 million NIH grant along with a milestone-based BARDA contract up to $45 million. The February 2022 round is listed among multiple funding activities, contributing to a total of over $161 million across 11 rounds by 2024.
