SHC008 (sh-Beta2Microglobulin) is a lentiviral plasmid that contains a shRNA sequence targeting the human β2 microglobulin transcript.
The shRNA insert is expressed under control of the human U6 promoter.
Human B2M is a MHC Class I molecule present on most cell types. It is commonly used as an endogenous control due to this universal expression.
SHC008 (sh-Beta2Microglobulin) is useful as a positive knockdown control in experiments using cell lines expressing β2 microglobulin.
The B2M clone (TRCN0000057254) was chosen from the available complete target set (GenBank Accession Number NM_004048) and has produced consistent knockdown of 80% compared to normal gene expression in the human epithelial lung carcinoma cell line A549 via quantitative RT PCR analysis.
Grow for 20-22 hours in TB-8gly medium (modified Terrific Broth medium, containing 8 ml/l glycerol instead of 4 ml/l) with 100 μg/ml carbenicillin, resulting in an increased plasmid stability as compared to ampicillin.
BCCM/GeneCorner uses the 'Terrific Broth, modified' from Sigma (cat. nr. T0918, Fluka). You can also prepare the medium yourself:
1. add the following to 800 ml distilled H2O:
- 12,0 g tryptone (enzymatic casein digest)
- 24,0 g yeast extract
- 8 ml glycerol
2. adjust to 900 ml with distilled H2O
3. sterilize by autoclaving (20 minutes at 121°C)
4. allow to cool to room temperature
5. adjust volume to 1000 ml with 100 ml of a filter-sterilized solution of 0,17M KH2PO4 and 0,72M K2HPO4
HOST STRAIN INFORMATION
Sigma recommends the host strain Escherichia coli K12 GC5 (catalogue number: G3169) for transformation with this shRNA control vector.
According to Sigma, the genotype of this GC5 strain is identical to the genotype of the Escherichia coli K12 DH5αT1R strain, which is a T1 bacteriophage resistant DH5α derivative.
Genotype: Φ80lacZΔM15 Δ(lacZYA-argF)U169 endA1 recA1 relA1 gyrA96 hsdR17(rk-, mk+) phoA supE44 thi-1 tonA (Ref.: http://www.sigmaaldrich.com/etc/medialib/docs/Sigma/Bulletin/shclngbul.Par.0001.File.tmp/shclngbul.pdf)
Other names of the plasmid are MISSION shRNA Human Positive Control Vector #1 Purified DNA and MISSION Beta-2-Microglobulin (B2M) shRNA Control Vector.
