In-gel low-melt agarose ligation

 

Vector, insert or both can be in 1% low melt agarose gel slice. These should be melted at 70C prior to use.

 

 

Prepare 2 tubes at 37C:

 

1.)

 

Vector gel slice:                    2ul

Insert/annealed oligos:       2-5ul

                                                                ________

H20:                                        10ul

 

Add oligos last.

 

 

2.)

 

5x ligase buffer:                   4ul

T4 ligase:                               2ul

T4 polynucleotide kinase:   1ul   (if required)

                                                                _______

H2O:                                   10ul

 

Take T4 ligase from freezer just prior to use, it is temp sensitive.

 

Mix the 2 tubes together. Incubate at RT for 3hrs, or 16C or 4C overnight. Use 1-2ul of this ligation reaction to transform competent cells.
