Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country.
Size (kb): 8.5000000000000000
Vector: pSLF373 (phagemid)
Promoters: Promoter for expression nmt1** (low strength; nmt1)
Construct size (kb): 8.5
Features: marker(s): ampR
promoter for expression: nmt1** (low strength; nmt1)
replicon: pMB1, f1
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): HindIII--5.6, 1.7, 1.0; EcoRI--7.4, 1.2; BamHI--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 cutting pSLF173 with SacI and XhoI, isolating the fragment containing the HA polylinker, and ligating into XhoI-SacI digested REP82X.
