The Department of Agriculture, specifically the Animal and Plant Health Inspection Service (APHIS), intends to issue a single-source contract to Biotechne-ProteinSimple for a maintenance and service plan for two Jess instruments located in Ames, Iowa. This procurement is critical for ensuring the proper functioning of the instruments, which are essential for analyzing antigens in master seed viruses and cell lines, thereby supporting compliance with the Virus Serum Toxin Act and facilitating the timely licensure of animal biologics. The estimated annual cost for these services is $27,824, and the justification for this sole-source contract is based on Biotechne's unique manufacturing capabilities, as confirmed by market research that identified no alternative vendors.
