Plasmids for tagging genes in situ

This page is dedicated to the very useful in-situ C-terminal tagging vectors developed in Thomas Seebeck's lab (A vector series for rapid PCR-mediated C-terminal in situ tagging of Trypanosoma brucei genes (2006) Oberholzer M, Morand S, Kunz S & Seebeck T. Mol Biochem Parasitol 145:117-20. DOI PMID) and variants that we have constructed including a selection in which we have incorporated a floxed positive-negative selection cassette so the markers can be re-used and there will be minimal disruption of the 3' UTR after cre-mediated marker elimination (one 34-bp lox sequence will remain). Please contact Michael Oberholzer for the original vectors and addgene for our variants. Some columns in the table are for our lab information only. Please inform me if any of the many links on this page yield the wrong item!

* Restriction sites within the drug-resistance genes may differ from those stated in the paper, in our experience.
** The Seebeck lab (and others personally) have reported that the 3x c-myc tag with antibody 9E10 (Santa Cruz Biotechnology) gives the most sensitive detection, with no background on immunoblots of procyclic or bloodstream forms.
