Next to the large amounts of insert and vector DNA, some of the methods require additional complex or time consuming working steps, many and/or long primers, or they have a low yield in colony numbers. Additionally, plasmids might not be efficiently digested, which may lead to false positive background due to uncut vector. Depending on the cloning method, more than 200 ng linear vector DNA per reaction is necessary, and quantitative preparation of the high molecular vectors by PCR is, however, not very effective. Commonly, the insert is amplified by PCR and with the exception of the last PCR based setups, the vector is prepared by restriction digestion, or alternatively by PCR in case no adequate restriction sites are present. Most of the alluded methods result in insert-vector fragments containing gaps or nicks that are filled and ligated by the cellular DNA repair machinery after transformation. Another possibility to combine vector and insert is to fuse both in a non-exponential PCR setup, which can be performed with linearized or circular vector –. The commercially available systems In-Fusion (Clontech), Geneart (Invitrogen) or CloneEZ (GenScript) are based on enzymatically prepared cohesive ends. These cohesive ends can remain as a result of incomplete PCR after vector and insert amplification, , they can be generated in a PCR setup or prepared enzymatically.
coli extracts or by annealing, if long single stranded cohesive ends are present in the vector and insert sequences. coli strains, by in vitro recombination using E. With this starting material seamless cloning can be performed by in vivo recombination using special E. Despite their differences in implementation, other seamless cloning methods start with a linearized vector and a PCR amplified insert containing sequences that are homologous to the vector on both ends. In a directional way, seamless cloning of PCR products into linearized vectors can be performed by applying type-II restriction enzymes. These methods can be divided in two groups, namely systems where additional sequences such as restriction or recombination sites are present at the insertion-boundaries after cloning – and seamless cloning methods without additional sequences.

The Gene Construction Kit software is available for both Windows and Macintosh users, and files can be shared across platforms allowing for easy collaboration. This DNA analysis software allows multiple files to be opened and displayed simultaneously, allowing DNA sequences to easily be copied and pasted between plasmids and vectors to represent real-world DNA cloning protocols. GCK eliminates tedious examination of DNA sequence data by automatically identifying open reading frames (ORF’s), keeping track of sticky ends during cutting and pasting of restriction enzyme digestion fragments, assisting with PCR primer design, and enabling comprehensive annotation of DNA sequence features.
GCK allows easy manipulation of DNA sequences, either graphically or as sequence text – quickly saving users both time and money.
The Gene Construction Kit®(GCK) program has been the preferred plasmid mapping software of leading researchers for more than 20 years.
