  2. Expression vector - Wikipedia

    en.wikipedia.org/wiki/Expression_vector

    Vectors used for E. coli expression can be used in this system although specifically designed vectors for this system are also available. Eukaryotic cell extracts may also be used in other cell-free systems, for example, the wheat germ cell-free expression systems. [41] Mammalian cell-free systems have also been produced. [42]

  3. Multiple cloning site - Wikipedia

    en.wikipedia.org/wiki/Multiple_cloning_site

    In expression vectors, MCSs are positioned between a promoter and a terminator to regulate gene expression. The upstream promoter can be either constitutive or inducible, responding to specific chemical inducers, while the downstream terminator ensures proper transcriptional termination and enhances plasmid stability.

  4. Vector (molecular biology) - Wikipedia

    en.wikipedia.org/wiki/Vector_(molecular_biology)

    Expression vectors produce proteins through the transcription of the vector's insert followed by translation of the mRNA produced, they therefore require more components than the simpler transcription-only vectors. Expression in different host organism would require different elements, although they share similar requirements, for example a ...

  5. Expression cloning - Wikipedia

    en.wikipedia.org/wiki/Expression_cloning

    Usually the ultimate aim of expression cloning is to produce large quantities of specific proteins.To this end, a bacterial expression clone may include a ribosome binding site (Shine-Dalgarno sequence) to enhance translation of the gene of interest's mRNA, a transcription termination sequence, or, in eukaryotes, specific sequences to promote the post-translational modification of the protein ...

  6. Short hairpin RNA - Wikipedia

    en.wikipedia.org/wiki/Short_hairpin_RNA

    Lentiviral delivery of shRNA and the mechanism of RNA interference in mammalian cells.. A short hairpin RNA or small hairpin RNA (shRNA/Hairpin Vector) is an artificial RNA molecule with a tight hairpin turn that can be used to silence target gene expression via RNA interference (RNAi).

  7. Protein production - Wikipedia

    en.wikipedia.org/wiki/Protein_production

    Mammalian in vivo expression systems have however low yield and other limitations (time-consuming, toxicity to host cells,..). To combine the high yield/productivity and scalable protein features of bacteria and yeast, and advanced epigenetic features of plants, insects and mammalians systems, other protein production systems are developed ...
