Example 3
1.5-2 μl of ligation mixture was transformed into 20 μl of ElectroMax DH10B T1 Phage-Resistant Competent Cells (Invitrogen, Cat #12033-015) by electroporation using MICROPULSER™ (BioRad) set at 1.7 kV using a 1 mm gap cuvette (BioRad, Cat #165-2089); after a pulse 1 ml SOC was added to cells and cells were incubated at 37° C. for 1 h with shaking at 200 rpm. 10 μl of recovery mixture was plated on LB agar plates containing ampicillin at a concentration of 100 μg/ml. Plates were incubated overnight at 37° C.
