Cell Line Authentication

The human genome is full of repeated DNA sequences which come in various sizes and are classified according to the length of the core repeat units, the number of contiguous repeat units, and/or the overall length of the repeat region. DNA regions with short repeat units (usually 2-6 bp in length) are called Short Tandem Repeats (STR). Creative Bioarray STR profiling is critical for verifying the identity of human cell lines, ensuring uniqueness of the cell line and detecting laboratory errors such as misidentification and cross-contamination of lines. The sensitivity and high power of discrimination makes our STR analysis an ideal choice for the various types of cell authentication.
