Pro-Lab Diagnostics launches Pro-Cult QC organisms in the US

Pro-Lab Diagnostics USA has launched Pro-Cult, a freeze-dried quality control organism line now available to US clinical, pharmaceutical, food, environmental and veterinary labs. The company says the product offers first-generation, NCTC- and NCPF-sourced reference strains with domestic fulfillment and audit-ready documentation.

Why it matters: - Pro-Cult gives US laboratories a domestically fulfilled QC organism option built from authenticated source strains. - The launch is aimed at labs that need documented reference material for CLSI M100, EUCAST, USP, Ph.Eur., CAP IQCP and FDA BAM workflows. - Pro-Lab positions the line as a second-source or alternative supply option for organizations concerned about QC continuity.

What happened: - Pro-Lab Diagnostics USA announced US availability of Pro-Cult, a freeze-dried quality control organism line. - The product is manufactured exclusively from authenticated strains held by NCTC and NCPF under a manufacturing licence from the UK Health Security Agency Culture Collections. - The line is now available to clinical, pharmaceutical, food, environmental and veterinary laboratories in the US.

The details: - Pro-Cult discs are first-generation, or P1, subcultures taken directly from NCTC or NCPF master strains. - The company says that approach leaves labs a four-passage working-stock budget before genetic drift becomes a risk. - Each lot is tested for identification and characterization at UKAS-accredited Lab #2496, operated by TCS Biosciences. - Per-lot Certificates of Analysis are available online by code, lot, strain or strain designation. - NCTC numbers and ATCC equivalents are printed on each Pro-Cult label and COA where applicable. - Pro-Lab says that setup allows existing CLSI M100, EUCAST and CAP IQCP SOPs to be updated with an addendum rather than rewritten. - The catalog includes 86 strains across 30 genera. - Listed organisms include E. coli NCTC 12241, S. aureus NCTC 12973, P. aeruginosa NCTC 12903, E. faecalis NCTC 12697 and K. pneumoniae NCTC 13368 for CLSI M100 and EUCAST AST QC. - Listed organisms also include Candida albicans NCPF 3179, Aspergillus brasiliensis NCPF 2275 and Bacillus subtilis NCTC 10400 for USP <61>/<62> growth promotion. - Clostridium sporogenes NCTC 532 is included for USP <71> sterility method suitability. - FDA BAM and food-safety organisms listed include Salmonella Typhimurium NCTC 12023, E. coli O157 NCTC 12900, Listeria monocytogenes NCTC 11994 and Campylobacter jejuni NCTC 11168. - The catalog also includes MRSA NCTC 13373, CRE K. pneumoniae NCTC 13440 and mcr-1 E. coli NCTC 13846 for antimicrobial resistance surveillance. - Fastidious organisms listed include Neisseria gonorrhoeae NCTC 12700, Haemophilus influenzae NCTC 11931 and Streptococcus pneumoniae NCTC 12977. - The full 86-strain catalog is available at the Pro-Cult catalog. - Pro-Cult ships from US domestic fulfillment as UN3373 Category B refrigerated, with no hazardous materials surcharge. - Pro-Lab says pricing matches existing GPO tier pricing on equivalent SKUs. - The company also provides a vendor-onboarding packet that includes ISO 13485:2016, ISO 9001 and ISO 14001 manufacturer certificates, ISO/IEC 17025 batch-testing accreditation, a supply-continuity SLA and a 30-day parallel-run SOP template.

Between the lines: - The launch is designed to reduce friction for labs that want a documented alternative to a long-established QC organism supply chain. - Online COA access and first-generation traceability are aimed at audit preparation and supply-continuity reviews. - The emphasis on NCTC and NCPF source strains suggests Pro-Lab is competing on provenance and documentation more than on product novelty. - Robert Rae, CEO of Pro-Lab Diagnostics USA, said US clinical and pharmaceutical labs have long relied on a single authenticated-source supplier and that Pro-Cult is intended to fit existing CLSI M100 and CAP IQCP frameworks without a QC plan rewrite.

What's next: - Labs can begin using the new product through Pro-Lab’s US fulfillment network. - Customers evaluating a switch can use the company’s 30-day parallel-run SOP template and onboarding packet. - Pro-Lab is directing buyers to its Pro-Cult site for the full strain list and purchasing details.

The bottom line: - Pro-Lab is betting that QC buyers will pay for traceable source strains, audit-friendly documentation and domestic supply continuity, not just organism availability.
