General Description:
Gene construction at Gene Link is performed by synthesizing
overlapping oligonucleotides of 80-100bases with sticky overhangs.
Appropriate oligos are phosphorylated which will be used for ligation. In
general, the scheme given below is followed.
1.
The customer supplied sequence is broken down into 80-100mers with
6-10 base overhangs. These oligos are checked for secondary structure and
hybridization patterns using oligo analysis software.
2.
The synthesized oligos are purified using polyacrylamide gel
electrophoresis. The purified oligos are annealed in pairs and ligated
sequentially. The ligated longer fragments are gel purified and ligated
again as required to obtain the complete construct.
3.
The construct is digested with appropriate restriction enzyme(s)
followed by gel purification for subsequent ligation to the vector.
4.
Transformed colonies are selected and processed for plasmid
purification and sequencing
