Abstract

PURPOSE:

To construct and confirm a recombinant eukaryotic expression plasmid pBABE-hygro-PLAP-1 containing periodontal ligament-associated protein(PLAP)-1 and a known FLAG sequence.

METHODS:

Firstly, the targeted DNA fragment was amplified from pCAG_PLAP-1 by PCR, then PCR product was inserted into p3×FLAG-CMV-10 vector with a known sequence of FLAG. Secondly, plap-1 gene and FLAG were obtained by PCR amplification from p3×FLAG-PLAP-1, then PCR product was inserted to proper sites of vector pBABE-hygro. Finally, the recombinant plasmid pBABE-hygro-PLAP-1 was confirmed by agarose gel electrophoresis and DNA sequence analysis.

RESULTS:

The construction of recombinant eukaryotic expression plasmid pBABE-hygro-PLAP-1 was confirmed through restriction enzyme maping analysis and DNA sequencing.

CONCLUSIONS:

The recombinant plasmid of pBABE-hygro-PLAP-1 is successfully constructed. It can be applied to plap-1 gene function research in the future. Supported by Natural Science Foundation of Shandong Province (Grant No.2R2010HM050).
