intermediate

Steps

1
Understand Gibson assembly overview

Learn that Gibson assembly is a method developed by Dr. Daniel Gibson for assembling multiple DNA fragments in a single tube isothermal reaction using Gibson assembly mastermix.

▶ 00:04
2
Prepare DNA fragments with overlaps

Prepare multiple DNA fragments with complementary overlapping ends using PCR or other methods, then add them to the Gibson assembly mastermix.

▶ 00:21
3
Incubate reaction at fifty degrees

Incubate the DNA fragments and Gibson assembly mastermix in a single tube at 50°C for 1 hour to initiate the enzymatic assembly process.

▶ 00:36
4
Create single-stranded overhangs enzymatically

The exonuclease activity in the mastermix creates single-stranded 3' overhangs that are complementary, allowing the DNA fragments to anneal together.

5
Fill gaps and seal DNA strands

DNA polymerase extends the 3' ends to fill gaps, and DNA ligase seals the remaining nicks to create a fully sealed double-stranded DNA molecule.

▶ 01:03
6
Use assembled DNA for applications

The final assembled double-stranded DNA product can be used as a template for PCR, RCA, transformation, or other molecular biology applications.

▶ 01:20
7
Apply Gibson assembly for cloning

Use the Gibson assembly cloning kit containing mastermix and competent cells to efficiently assemble and clone multiple DNA fragments into a vector within 2 hours.
