ExpressionLibraryScreening(Procaryotic)UsingAPFusionProteins
Outline:Bacteriophage lambda is a linear double stranded DNA, approximately 50 kB in size. The two sticky ends help the phage to recircularize after entering the bacterial host cell. A cDNA library is a representation of mRNA's that are expressed in a certain tissue at a certain time (e.g. rat d9 pseudopregnant decidua). Each phage contains one cDNA that was 'grabbed' by the poly-A tail and cloned into a ......阅读全文
