| Vector Information： | Size (kb): 5.6100001335144040 DESCRIPTION OF VECTOR COMPONENT: Name of vector: pFC54 Intact vector size: 5.440 Type of vector: plasmid Cloning sites: Polylinker sites: Host range: Escherichia coli Features (with orientation and position when available): marker(s): ampR promoter: lambdaPL replicon: pMB1 Cross references: Vector: pFC54.t (plasmid) Construction: pFC54, pHCW801 Marker(s):ampR Construct size (kb): 6.099999904632568 |
| Applications： | cloning vector expression vector |
| Comments： | Restriction digests of the clone give the following sizes (kb): EcoRI--5.0, 1.15; BamHI--6.1; HindIII--6.1; HindIII/BamHI--5.6, 0.5. Construct contains a positive retroregulatory element which increases the level of production of the IL2 (Ser125) using a temperature regulated control cassette in a temperature-regulated ColE1 copy mutant plasmid vector. This should not be grown at temperatures exceeding 30C. The depositor recommends using ampicillin at 100 mcg/ml. The strain is temperature-inducible. The clone contains a lambdaPL promoter. This was constructed from a SphI/XbaI fragment of pFC54 ligated to a 655 bp SphI/XbaI fragment of pHCW801 containing the C-terminal 255 bp of Ser125 IL-2, 36 bp of 3 untranslated IL-2 cDNA and 394 bp of the positive retroregulatory element. |
