ARP-2850??Toxoplasma gondiiTransformation Vector (pminCAT/HXGPRT+), Recombinant in Escherichia coli (Plasmid/Vectors)|Toxoplasma gondiiTransformation Vector (pminCAT/HXGPRT+), Recombinant in Escherichia coli|Toxoplasma gondii|-60°C or colder?|DS Roos, EO KendallAcknowledgment for publications should read “The following reagent was provided by the NIH AIDS Reagent Program for distribution by BEI Resources, NIAID, NIH: Toxoplasma gondii Transformation Vector (pminCAT/HXGPRT+), Recombinant in Escherichia coli, ARP-2850, contributed by Dr. David S. Roos."|Quantity limit per order for this item is 1. This item can be ordered twice a year. Orders over this limit will be sent to NIAID for approval before shipment.
ARP-2850 is an Escherichia coli (E. coli) DH5a stock expressing a transformation vector clone, pminCAT/HXGPRT+, containing a chloramphenicol acetyltransferase (CAT) coding sequence (GenBlock cassette; Pharmacia) flanked by 5' and 3' sequences derived from the Toxoplasma gondii dihydrofolate reductase-thymidylate synthase (T. gondii dhfr-ts) gene cloned into Bluescript pKS+ (Stratagene) polylinker EcoRV-SmaI sites. Both EcoRV-SmaI sites were destroyed during the cloning process. A unique BglII site is located upstream of CAT, and a unique PstI site is downstream. A T. gondii hypoxanthine-xanthine-guanine phosphoribosyl transferase (HXGPRT) minigene containing 5' genomic flanking sequences fused to cDNA encoding isoform I was cloned into the polylinker XhoI site upstream of CAT and in the same orientation. The XhoI fragment also contains some polylinker sequences from pGEM (Promega).
ARP-2850 is suitable for transient expression of CAT in transfected T. gondii parasites and/or stable transformation of HXGPRT-deficient T. gondii host strains (ARP-2857 and ARP-2860). The HXGPRT gene can be removed as a ~ 2000 base pair XhoI fragment for use as a selectable marker in other vectors; clone pminiHXGPRT (ARP-2855) works slightly better for this purpose. Clone pminCAT/HXGPRT+ is identical to pminCAT/HXGPRT- (ARP-2851) except for the orientation of the HXGPRT-containing XhoI fragment. ClonepminCAT/HXGPRT+ exhibits higher transformation frequencies than ARP-2851, however, possibly because of the strong hairpin in ARP-2851 produced by the polylinker sequences introduced with the HXGPRT minigene.
Each vial contains approximately 500 ?L of E. coli DH5a with pminCAT/HXGPRT+ in Luria Bertani (LB) broth supplemented with 10% glycerol.
