载体说明

The pcomb3XSS is the modified version of pComb3X。 The “SS” refers to the double stuffer, a 1200bp stuffer in the Fab light chain cloning region bounded by SacI and XbaI restriction sites and a 300bp stuffer in Fab heavy chain cloning region bound by XhoI and SpeI restriction sites。 Also, the 1600bp double stuffer (both stuffer plus the leader sequence between the Fab light chain and heavy chain cloning regions) can be removed by SfiI digest so that non-Fab genes of interest can also by cloned。 Addition of 6xHis and HA tags for detection and purification, amber stop codon upstream of geneIII to produce soluble protein by switching to a non-suppressor strain of E。 coli (e。g。 Top10F',HB2151,WK6)
