Size (kb): 8.5000000000000000
Vector: pSLF173 (phagemid)
Promoters: Promoter for expression nmt1 (full strength)
Construct size (kb): 8.5
Features: marker(s): ampR
promoter for expression: nmt1 (full strength)
epitope tag (N-terminal): hemagglutinin (HA) triple tag
encodes an epitope tag for protein isolation or monitoring
Restriction digests of the clone give the following sizes (kb): BamHI--8.5; EcoRI--7.3, 1.2; PstI--8.5.
The fission yeast tagging vectors, pSLF173 (ATCC 87612)
, pSLF273 (ATCC 87613)
and pSLF373 (ATCC 87614)
, contain three versions of the nmt1 promoter: full strength (nmt1), medium strength (nmt1*) and low strength (nmt1**), respectively.
The weaker promoters (nmt1* and nmt1**) contain mutations that attenuate both repressed and induced levels of expression.
Each version of the nmt1 promoter can be expressed at low or high levels in thiamine-free media.
The vector was designed to tag expressed protein at N-terminus with triple HA tag, which contains an internal BamHI site. The vector lack a stop codon.
The vector was constructed by 1) amplification by PCR with primers designed to flank the triple HA tag in Bluescript-HA and to modify the polylinker, 2) gel purification of the PCR product and digest with XhoI
and 3) ligation into REP4X cleaved with XhoI and SmaI.
