  • Extensive set of restriction sites in polylinker, many with unique 4-base overhangs
  • Blue/white selection
  • Opposing T7 promoters for making RNA transcripts in either direction or double-stranded RNA using the HiScribe RNAi Transcription Kit (NEB #E2000S)
Description:
LITMUS 38i is a multi-purpose cloning/in vitro transcription phagemid vector. The molecule is a small, double-stranded circle 2,814 base pairs in length (molecular weight =1.8 x 106 daltons).

Source:
LITMUS 38i is isolated from E. coli ER2738 by a standard plasmid purification procedure.

Advantages:
  • Small (< 3 kb), high copy number.
  • Ampicillin resistance.
  • Single-stranded (M13) DNA replication origin.
  • Compatible with pUC/M13 sequencing primers as well as LITMUS sequencing primers.
Concentration:
500 μg/ml


Storage Conditions


Storage Conditions:
10 mM Tris-HCl
1 mM EDTA
pH 8.0 @ 25°C

Storage Temperature:
-20°C


Notes


General notes:
  1. Appropriate strains of E. coli containing the LITMUS 38i plasmid form blue colonies on X-gal plates; when a fragment is inserted in the polylinker, the colonies are white. Blue/white selection is best achieved by plating on a rich media (e.g. LB) supplemented with X-gal (40 µg/ml) and IPTG (0.1 mM)

FAQs


  1. How homogeneous is the DNA/ how much is supercoiled?
  2. Are the plasmids cesium purified?
  3. What primers should I use to sequence an insert (pUC19, pNEB193, LITMUS)?
