黑线鳕鱼核酸标准样品的研制

The development of a Melanogrammus aeglefinus DNA standard sample

为推进鱼类物种鉴定,填补黑线鳕鱼核酸标准样品国内空白,本研究制备了黑线鳕鱼核酸标准样品。研究采用8家单位合作定值的方法,确定了该标准品的DNA质量为(2.02±0.07)μg,k=2;DNA纯度为(1.82±0.08),k=2。并对该标准品的均匀性、稳定性进行了测试,结果表明该样品均匀性与稳定性均达到国家标准样品的技术要求,可用于黑线鳕鱼物种鉴定中方法验证和质量控制。

To help identify marine fish and provide a reference standard for identification of Melanogrammus aeglefinus, a standard sample for Melanogrammus aeglefinus is established in this study. With collaboration of eight labs, concentration and quality of DNA are tested. The concentration value is （2.02-＋0.07） txg （k=2） and the purity value of DNA is 1.82-＋0.08 （k=2） which indicates good quality of samples. PCR and electrophoresis are used to test the uniformity, stability and value analysis of the samples. The results show that these samples in this study meet the technical requirements of national standards and that the method can be used for calibration and quality control of Melanogrammus aeglefinus.
