Failure to monitor cell lines for cross-contamination or misidentification, a problem that has persisted for cell lines for decades, may result in compromised data and ultimately irreproducible results. How to solve this problem? A Misidentification due to labeling errors B Incorrect classification by pathologists C Cross-contamination with other cell types

Intruduction What is Short tandem repeat? Short tandem repeat is a microsatellite, consisting of a unit of two to thirteen nucleotides repeated hundreds of times in a row on the DNA strand. Standards for Cell Line Authentication short tandem repeat [STR] profiling

DNA Polymorphisms Most of our DNA is identical to DNA of others. However, there are inherited regions of our DNA that can vary from person to person. Variations in DNA sequence between individuals are termed "polymorphisms". STR STRs are short sequences of DNA, normally of length 2-5 base pairs, that are repeated numerous times in a head-tail manner. These Sequences with the highest degree of polymorphism are very useful for DNA analysis in forensics cases and paternity testing. STR Background
