Hi

Thanks in advance

I think this is the wrong venue to ask this question. I would contact scientists who have published in the domain you are interested in. In particular, those supported by the US National Institutes of Health (NIH) are often obliged to share data as part of their data sharing plan. Likewise, many journals expect data to be openly shared.
