In which formats is the Prostate Cancer Panel DNA Reference Standard available, and do they all contain the PTEN loss variant?​

The Prostate Cancer Panel Reference Standard is available in FFPE format (HD848), and does not contain the PTEN loss variant (https://horizondiscovery.com/en/reference-standards/products/prostate-cancer-panel-ffpe-reference-standard?catalognumber=HD848). 

The cfDNA version of the Prostate Cancer Panel Reference Standard (HD836) includes PTEN loss in the list of verified variants (https://horizondiscovery.com/en/reference-standards/products/prostate-cancer-panel-cfDNA-reference-standard?catalognumber=HD836). HD836 is accompanied by the Prostate Cancer Panel cfDNA negative control, HD837 (https://horizondiscovery.com/en/reference-standards/products/prostate-cancer-panel-cfdna-reference-standard-negative-control?catalognumber=HD837).​

There is a separate FFPE reference standard available for PTEN loss specifically: the PTEN Loss FFPE Reference Standard, HD864 (https://horizondiscovery.com/en/reference-standards/products/pten-loss-ffpe-dna-reference-standard).
