A Simple Variable Number of Tandem Repeat-Based Genotyping Strategy for the Detection of Handling Errors and Validation of Sample Identity in Biobanks.

Biobanking biological samples involve multiple handling, processing, and labeling steps. Each step may be a source of error, which if unnoticed or uncorrected may have consequences for research. We aimed to develop a simple and inexpensive genotyping method that would be valuable to detect such errors and confirm sample identity.
