From J5 manual, "The SLIC, Gibson, CPEC and SLiCE assembly methods" (http://j5.jbei.org/j5manual/pages/22.html) :
"SLIC, Gibson, CPEC, and SLiCE are related methods that offer standardized, scarless, (largely) sequence-independent, multi-part DNA assembly".
Also: "Despite their differences in implementation, SLIC, Gibson, CPEC, and SLiCE assembly methods all start with the same starting materials and result in the same final products"
A guide to Gibson Assembly: http://www.synbio.org.uk/dna-assembly/guidetogibsonassembly.html
NEBs NEBuilder software for Gibson assembly can be used to design primers for Gibson assembly and SLIC: http://nebuilder.neb.com/
In the NEBuilder, the overlaps are designed to achieve a minimum Tm value of 48°C.
Hetero-stagger PCR and Enzyme-Free cloning
Articles related to "hetero-stagger PCR" and "enzyme free cloning" (Conceptually equal to PIPE/iPCR):
|Liu 1996: Hetero-stagger cloning: efficient and rapid cloning of PCR products||Generation of related PCR products by using two sets of primers, identical except for a 3bp GGG addition at 5' end in one set. After mixing the PCR products, denaturing and reannealing, a mixed product with CCC overhang is produced, which can be cloned by ligation to a vector with a GGG overhang.|
|Tillett and Neilan 1999: Enzyme-free cloning: a rapid method to clone PCR products independent of vector restriction enzyme sites||Builds on Liu 1996. Both insert and vector is prepared by hetero-stagger PCR and mixed before undergoing denaturation/annealing to give the desired construct.

de Jong et al. 2007 comments: "An ideal cloning method should require small amounts of insert and vector DNA, and be cheap, effective, easily automatable and insensitive to variations in DNA concentrations . Ligation independent cloning  meets most of these criteria, but we observed substantial variation in cloning efficiency. Parameters influencing efficiency are the amount of PCR product, purity of the PCR product, exact temperature of T4 DNA polymerase treatment and T4 DNA polymerase activity differences, caused by enzyme batch variations and activity loss over time (unpublished results). As a result, PCR products can be under- or overtreated by the exonuclease activity of T4 DNA polymerase, which can significantly influence the cloning efficiency."

Note that by cutting a vector with two restriction enzymes and using SLIC to insert a sequence, the restriction sites may be destroyed. Always consider the resulting sequences carefully.

|Li & Elledge 2007||"Harnessing homologous recombination in vitro to generate recombinant DNA via SLIC."||http://www.ncbi.nlm.nih.gov/pubmed/17293868|
According to Olieric 2010 (Supplementary material), "The critical parameter for success is the sequence of the overlap; some constructs work amazingly well, while others do not". The cause could plausibly be stable secondary structures? Stable secondary structures in the single-stranded DNA will compete with annealing of the fragments.
Quote from Li and Elledge 2007:
"Excision by the proofreading exonuclease of T4 DNA polymerase has proven to be the most reproducible and easiest to manipulate method for generating 5¢ overhangs. Although much less efficient, iPCR also gives substantial stimulation of transformation. This might be sufficient for routine subcloning purposes, although there is likely to be more variability depending on the completeness of the PCR synthesis"
Protocols for LIC/SLIC and related methods:
|Author(s)||Hsiao 1993||Aslandis & Jong 1990|
|Method:||With RecA||Without RecA||With iPCR||Exonuclease III||LIC|
Two-step SLIC has the advantage that larger amounts of vector can be prepared beforehand, and used in several annealing reactions.
Mix 5 μl of purified PCR product (100–300 ng) and 1 μl (50 ng) of the appropriately linearized vector, having 15+ bp homologous overlap, before transformation.
Quote from the above: "Perhaps the most significant limitation of the Golden Gate method is that it is less sequence-independent than SLIC/Gibson/CPEC/SLiCE, in the sense that, like BioBrick assembly, the selected type IIs recognition site (e.g. BsaI) should be absent from the internal portions of all of the DNA fragments to be assembled" From the same J5 website (http://j5.jbei.org/j5manual/pages/22.html):
"Since there are no (or very few) re-amplifications of a given template sequence, PCR-derived mutations are not propagated to the same extent as one would anticipate for standard SOEing reactions. Like SLIC and Gibson assembly, CPEC is standardized, scar-less, and largely sequence-independent."
RF cloning can be used to insert a sequence into a plasmid without removing any of the original plasmid sequence, or to replace a portion of a plasmid with a new sequence. RF cloning is accomplished using two PCR steps. In the first PCR, the sequence to be inserted is amplified (or synthesized) to give a product with the insert sequence flanked by sequences homologous to the plasmid. In the second PCR, the product of the first step is used as a "megaprimer" To insert a sequence into a plasmid without removing any of the original plasmid sequence, the plasmid-binding regions of the megaprimer should bind to the plasmid directly adjacent of each other, as any sequence in the plasmid between the two primer binding sites will be lost. To replace a portion of a plasmid, the plasmid-binding flanking sequences of the megaprimer must be designed to bind such that they flank the area to be replaced. If RF cloning is used to replace a portion of a plasmid, the new sequence should be about as long as the sequence it is replacing.

|Method||Summary||Advantages||Disadvantages||Time (for assembly from prepared vector and insert)||Experiences||Reference|
|Conventional (restriction enzymes)||Restriction digestion and ligation||Predictable. With respect to vector, sequence dependence is limited to a few bp, thus cloning is robust with respect to mutations in the vector.||Time-consuming. Requires restriction digestion of insert and vector followed by ligation. Requires suitable restriction sites in vector. Cloning is subject to sequence limitations in insert (must not contain restriction sites used for cloning). Restriction reaction can be spoiled by contaminating DNA flanked by restriction sites used.||From 3 h to overnight|
|Blunt-end ligation||Ligation of blunt-ended fragments||Flexible, does not require specific restriction sites.||10-100x less efficients than cohesive-end ligation.
