摘要
We describe a general method for the synthesis and cloning of cDNA, applicable to cases in which the availability of biological material for mRNA extraction is extremely limited. A protocol allowing amplification of a heterogeneous mixture of cDNAs by the polymerase chain reaction has been devised and applied successfully to the construction of an apparently representative cDNA library, using as a model of a scarce RNA source 50 mouse ovulated eggs that can yield a maximum of 1.75 ng of poly(A)+ RNA. However, about 5% of the material obtained after amplification was adequate for cloning. Using the cloned sequences, we have derived a preliminary indirect measurement of the sequence complexity of the maternal poly(A)+ RNA in this mammalian oocyte. © 1990.
