Determine if the following text contains a data availability statement. Answer with 'yes' or 'no'.

Text: Purified PepP was stored at −80°C over a period of 15 days. During this time, aliquoted samples were checked for residual activities and no significant inactivation of PepP was observed (97% residual activity; **data** not shown). Additionally, the influence of 6 alternating cycles of freezing and thawing was observed. The residual activity of PepP was 87% after these cycles (data not shown).<|eot_id|><|start_header_id|>assistant<|end_header_id|>
