【Abstract】 Identification of transgenic animals plays an essential role in transgenic study. In this report, the technical progress for screening transgenic offspring was briefly reviewed and a simple and efficient assay was introduced. Transgenic animals were identified and confirmed by PCR along with further restriction endonuclease analysis. Some factors on PCR, such as the design of primers, the concentration of Mg\+\{2+\} and DMSO, the annealing temperature and so on, were optimized. In order to assess the validity of the template, a pair of primer which is specific for the endogenous beta-glolin gene was used as control. The results showed that the assay was a reliable, sensitive, rapid and well-repeated to identify transgenic animals.更多还原
