About this file
This Limited Source/Brand Name Justification document from the USDA Agricultural Research Service details the procurement of a specialized Bio-Rad NGC Fraction Collector for the Cattle Fever Tick Research Unit. The instrument is specifically needed to enable automated, high-throughput collection of eluate fractions during liquid chromatography workflows, to be paired with a Bio-Rad NGC Scout Chromatography System for protein purification and molecular interaction studies.
The justification explains that the NGC Fraction Collector is uniquely designed to integrate exclusively with the Bio-Rad NGC Chromatography platform, offering seamless integration through proprietary communication protocols and ChromLab software. Market research conducted by reviewing Intramalls and the Bio-Rad website confirmed no alternative manufacturers provide a functionally equivalent product with the same level of hardware, software, and protocol integration. The procurement supports the agency's research objectives of developing novel anti-tick strategies, including vaccines and targeted biologics to protect the U.S. cattle industry from tick-borne diseases.
