Your custom protein expression will be optimized by engineering an expression construct with a codon-optimized DNA insert, a strong promoter, an efficient ribosome binding site, a high copy number and combining it with an appropriate host. High level of protein expression also depends on stability, solubility, and folding pathway of the protein product. Accordingly, we will optimize these protein expression parameters when such optimization is necessary.

following optimizations are offered:

  • Plasmid
  • Strain
  • Inducer amount
  • Temperature
  • Medium
  • Length of induction

All optimization projects include 1) project consultation 2) optimization in shake flasks 3) isolation of soluble and insoluble proteins 4)SDS-PAGE analysis of soluble and insoluble extracts.

MBS excels at recombinant protein production and advanced chemical modifications including fluorophore attachment, biotinylation, and chemical crosslinking.  We specialize in both small-sale (ug – mg scale) and large-scale production (gram- kg scale), with considerable expertise in production scale-up to larger quantities and batch sizes.  Highest quality standards are carefully monitored at every stage in the process.

de novo Construction

Typical project workflow (each project will be evaluated individually to meet client needs). Most of our services listed below are also available individually as a fee-for-service.

  • Plasmid design/codon optimization (highly recommended)
  • Selection of cell strain
  • mg scale (shake flask) expression optimization
    • includes isolation of soluble and insoluble protein and SDS-PAGE analysis
  • 10-130 L fermentation (animal-free available)
  • Harvest
  • Mechanical Lysis
  • Purification

Small-Scale Protein Production:

 In addition to single protein production, Lytic Solutions also has the capacity to handle high-throughput variant gene synthesis and protein production capabilities.  If you are having trouble expressing your protein, let us try.  We have specialized equipment, tools, and experience to get orders of magnitude higher production than less equipped facilities.

Large Scale Production & Industrial Process Development:

With 10L, 20L, 30L, 75L, and 130L fermentation vessels, Lytic Solutions can handle gram to kilogram protein quantity production capacity.  We can help troubleshoot your protein production issues and then produce massive quantities of your recombinant protein.
