Minimal length requirement of the single-stranded tails for ligation-independent cloning (LIC) of PCR products.
The ligation-independent cloning of PCR products (LIC-PCR) is a versatile and highly efficient cloning procedure resulting in recombinant clones only. Recombinants are generated between PCR products and a PCR-amplified vector through defined complementary single-stranded (ss) ends artificially generated with T4 DNA polymerase. This procedure does not require restriction enzymes, alkaline phosph...
متن کاملQuick and Clean Cloning: A Ligation-Independent Cloning Strategy for Selective Cloning of Specific PCR Products from Non-Specific Mixes
We have developed an efficient strategy for cloning of PCR products that contain an unknown region flanked by a known sequence. As with ligation-independent cloning, the strategy is based on homology between sequences present in both the vector and the insert. However, in contrast to ligation-independent cloning, the cloning vector has homology with only one of the two primers used for amplific...
متن کاملDirectional cloning of PCR products.
INTRODUCTION This protocol is for directional blunt-end cloning of DNA fragments. The target DNA is PCR-amplified, 3'-extensions are polished with Pfu DNA polymerase, and the amplicon is ligated to a blunt-ended plasmid DNA. The products of the ligation reaction are used to transform competent Escherichia coli. A restriction enzyme is added to the ligation reaction (Liu and Schwartz 1992) to re...
متن کاملBandstab: a PCR-based alternative to cloning PCR products.
In many DNA amplification reactions, extra fragments arising from nonspecific mispriming, a mixture of target templates or allelic variation may be generated in addition to the desired product. Some nonspecific bands can be reduced by more stringent annealing conditions, but in cases of allelic variation or other mixed targets, the amplification products may be of the same length but differ by ...
متن کاملBlunt-end Cloning of PCR Products.
INTRODUCTION Incubation of a blunt-end ligation reaction in the presence of an excess amount of an appropriate restriction enzyme can dramatically increase the yield of recombinant plasmids. The role of the restriction enzyme is to cleave circular and linear concatemers at restriction sites that are re-formed when linear, blunt-ended plasmid molecules ligate to themselves. In almost all cases, ...
