Sigma-Aldrich, Family Tree DNA

Premium
Sigma-Aldrich has launched the mirPremier microRNA isolation kit for miRNA purification from diverse biological sources. The kit enables scientists to purify and enrich miRNA, along with other small RNAs, directly from cells or tissues, including mammalian cell cultures, animal tissues, microbial cultures, and plant tissues, and difficult-to-extract tissues, such as grape leaf. The kit yields “highly purified miRNA samples with no detectable large RNA," according to the company.
 

 

Family Tree DNA last week announced the launch of a comparative database for full mitochondria sequences; MyMaps, a personalized interactive genetic mapping system; and a test that allows participants to map genetic relationships through the Y chromosome.
