Claviceps paspali Stevens & Hall – Mutants F-140 and F-237
Description:
Claviceps paspali is a grass-infecting ergot fungus with unique biosynthetic potential. The F-140 and F-237 mutant strains, deposited with ATCC (13895 and 13893), are well-characterized producers of lysergic acid derivatives. These mutants form the historical foundation of early ergot alkaloid research and remain valuable for biochemical, pharmaceutical, and genetic studies.
Available Strains:
1 × F-140 (ATCC 13895)
1 × F-237 (ATCC 13893)
Package Includes:
• 1 × Verified culture on 100 mm CellTreat Grip ring petri dish. Usually on PDA.
• 1 × Slant for medium-term refrigerated storage.
Backup Guarantee: Valid for 2 years. Buyer may request 1 replacement slant in case of culture loss (nominal processing + shipping fee).
Alkaloid Production:
• F-140 and F-237 are mutants known for lysergic acid derivative biosynthesis.
• Key reference: U.S. Patent 3,038,840 describing their properties and potential.
Applications:
• Lab and Biotech: Substrate for lysergic acid production, metabolic engineering, and ergot alkaloid pathway studies.
• R&D: Historical and modern reference strains for ergot biosynthesis.
🧫 Culturing Information
• Media: PDA (Potato Dextrose Agar).
• Colonization temps: 24–26 °C.
• Growth characteristics: Typical ergot morphology, slow-growing compared to saprotrophic fungi; requires patience in handling and subculture.
Storage:
• Refrigerated slants at 4–8 °C: stable 12–36 months.
• Long-term: cryopreservation preferred.

Claviceps Culture Disclaimer
Claviceps species (e.g., Claviceps purpurea) are filamentous fungi known for producing alkaloids such as ergotamine and related compounds. These alkaloids are pharmacologically active and, in some cases, toxic. Because of this, Claviceps cultures must be handled with extreme care and only by qualified individuals in properly equipped laboratory facilities.
By requesting, purchasing, or working with Claviceps cultures, you acknowledge and agree to the following:
• Research Use Only - These cultures are provided strictly for legitimate research, educational, and strain-improvement purposes. They are not intended for human, veterinary, agricultural, or food use.
• Safety Requirements - Handling Claviceps requires biosafety-level procedures appropriate for toxin-producing fungi. Cultures must only be maintained in facilities with proper containment, protective equipment, and waste disposal practices.
• Legal Compliance - You are solely responsible for ensuring that possession, transport, or research with Claviceps cultures complies with all applicable local, national, and international laws and regulations.
• No Liability - The provider assumes no responsibility or liability for misuse, improper handling, or consequences arising from possession or experimentation with Claviceps cultures. By acquiring cultures, you accept full responsibility for their safe and lawful use.
• Restricted Applications - These cultures must not be used for direct production of controlled substances, pharmaceuticals, or agricultural infection experiments outside of approved institutional research protocols.
