• Transform construct into E coli strain
• Prepare and linearise plasmid and transform 3-5 yeast strains (Hefe)
• Small scale expression, screening & expression pilot
• Scale up culture and purification
• Affinity purification (Ni2+, GST, etc)
• QC: SDS-PAGE analysis, western blot, purity, concentration
• Project report
Lead time: 9-10 weeks
Remarks:
Pichia pastoris expresses a very low amount of secreted proteins meaning the majority of proteins in the media represent the recombinant protein of interest. This property clearly simplifies the downstream protein purification process.
Pichia pastoris can be grown at high cell density. Thus,this host organism allows for high yield protein production.
Pichia pastoris possesses the complete post-translational machinery characteristic of eukaryotic cells. Thus, this host organism is able to perform phosphorylations and glycosylations (different from those observed in mammalian cells protein expression).
To conclude, Pichia pastoris protein expression is the first choice for the production of secreted proteins.

Fluorescent substrate for Furin protease
Specifications
Sequence: Pyr-Arg-Thr-Lys-Arg-AMC (AMC = 7-Amino-4-methylcoumarin).
Molecular Mass: 827.94 Da.
Purity: > 95% based on HPLC.
Quantity: 5 x 200 mg lyophilized powder
Price: Inquiry
Assay Conditions
A fluorescence plate reader with excitation at 380 nm and emission at 460 nm is recommended for
the measurement of the enzymatic activity. Depending upon individual enzymes, the substrate can
be used at final concentrations between 10 - 100 µM in a total of 100 µL reaction mixture.
Applications
Hydrolysis of Arg-AMC amide bond releases AMC, a highly fluorescent group.
It is an excellent substrate for furin-like proprotein convertases
MESH: Human Furin , West Nile Virus NS3 Protease
