Abstract:

In order to clone Bashibay sheep SPLUNC1 gene and express its protein,total RNA was extracted from lung of Bashibay sheep,RT-PCR was used to amplify SPLUNC1 gene open reading frame sequence,the gene fragment was inserted into eukaryotic expression plasmid pPIC9K to construct plasmid pPIC9K-SPLUNC1,then the plasmid pPIC9K-SPLUNC1 was linearized and electroporated into Pichia pastoris GS115,the protein was induced by methanol,and the target protein was identified by SDS-PAGE and Western blotting.The results showed that the 748 bp SPLUNC1 gene was successfully amplified by RT-PCR;The plasmid pPIC9K-SPLUNC1 was consistent with expected results after PCR,enzyme digestion and sequencing identification;Detection results of SDS-PAGE and Western blotting showed that the SPLUNC1 protein was successfully expressed with 25.53 ku.This study laid a foundation for further research of SPLUNC1 protein biological activity of Bashibay sheep.
