摘要: The invention discloses a heterozygous-mutation dried-blood-spot positive quality control product applicable to detection of mutant genes deafness. is characterized in that DNA fragments containing mutation sites or plasmids the are mixed with whole blood prepare dried spots; comprise 11 four such as GJB2, GJB3, 12SrRNA and SLC26A4. mutantgenes deafness close clinical sample, has advantages needed volume less, sample collection convenient, biological stability can be maintained, risk reduced, transportation storage convenient. still used normally after being stored for 2 years at temperature 4 DEG C, result not influenced.
