The … TīmeklisDNA Sizer: Phage Lambda DNA / Pst I is ideal for qualitative and quantitative analysis of dsDNA. Description: The PstI digest of phage-DNA yields the 29 fragments. Lambda DNA was completely digested by PstI, phenol extracted, ethanol precipitated, dissolved in 10 mM Tris-HCl (pH 8.0) and 1 mM EDTA. The marker is ready-to-use.

TīmeklisThe lambda red system is an alternative method that can be used for cloning or genome engineering and is based on homologous recombination. It allows for direct modification of DNA within E. coli and is independent of restriction sites. The lambda red system is derived from the lambda red bacteriophage and its use as a genetic … TīmeklisPhage lambda is a parasite of enteric bacteria such. as Escherichia coli. Unlike T4 it only has a single tail fibre and it has a tapering tail tube. Like T4, however, it still injects its DNA into the host cell, although the tail is non-contractile. The lambda. phage has a remarkable developmental sequence which is quite well understood, and an ...
