◆ VC-013 |
Experimental Data:
The result of ligation using the
control insert DNA and reagents provided in yT&A cloning kit.
*In this colony PCR, the size of
the band on the gel is larger than the insert DNA size by about
150bp.
|
*Before the insert is incorporated
into the yT&A cloning vector, there is only one HindIII site and
no Bg/II site. After the incorporation, the T and A nucleotide
on the the insert will complement the sequence on the vector and
generate these two new site. This merit of yT&A vector makes
cloning more economical and convenient. |
