In partnership with the Centre for Environment, Fisheries & Aquaculture Science (Cefas), PHE provides reference materials (RMs) for norovirus (genogroups I and II) and hepatitis A virus.
The discs consist of viruses in a solid water-soluble matrix that is stable for at least one year from manufacture, easy to use and suitable for a wide range of applications. The LENTICULE discs must be stored at -20°C ± 5°C, although short periods at ambient temperature such as during transportation, does not affect viability. All LENTICULE discs are supplied with a minimum expiry date of three months from date of purchase. Each pack of 10 LENTICULE discs comes with easy-to-follow instructions; all orders will be supplied from a single batch.
|Catalogue number||Reference Material||Genome copies per LENTICULE disc range|
|RM000HAV||Hepatitis A virus (HAV)||
5.7x102 – 1.7x103
1.3x102 – 5.5x102
2.8x102 – 1.4x103
The RMs are supplied with a certificate of analysis which gives reference values. These values are generated using a real time RT-PCR using Cefas’ ISO 17025 accredited procedures for virus quantification based upon ISO 15216-1 (Method for Quantification). Reference values are generated using a real time RT-PCR using Cefas’ ISO 17025 accredited procedures for virus quantification based on ISO 15216-1 (Method for Quantification).
