Epistem is able to provide gene expression information from a broad range of tissue types.  Our proprietary plucked hair biomarker platform provides a simple to apply and minimally invasive technique to access epithelial tissue, to assess the gene response of a patient.

The hair samples collected act as effective surrogate tissue for monitoring drug activity and response to treatment.
 
Both efficacy and adverse gene responses can be tracked frequently by simply plucking patient hairs. Use of a hair biomarker enables the tracking of a drugs response over time and helps improve the methods for selecting dose and assessing the overall effectiveness of treatment.

Use of the hair biomarker enables frequent measure of drug effect. This is a critical factor, where a patient undertakes a course of treatment spanning weeks and months, in tracking the effectiveness of response.
