How do I request a quotation?

Click on the “Request a Quote” link at the bottom of this page, or click here. One of our scientists, likely not Rosalind Franklin, will provide you with a quotation or contact you regarding any questions within 2 business days.

What starting materials are required to begin a project?

We are able to begin projects at many different stages, so the starting material will be dependent on the type of project you are requesting.  Typically, most projects begin with customer-provided plasmid DNA or an amino acid sequence.  Sequence information can be provided in the quote request form or attached in a separate document and submitted with the completed quote request form.

Where do I send starting materials?

Digital information, such as sequences or protocols, can be sent to QuoteRequest@proteos.com.  Physical starting material can be shipped to the address below.  Please reference your quotation number on the shipment or packing slip.

Proteos, Inc.
4717 Campus Drive
Kalamazoo, MI 49008

What is your lead time for projects?

We are able to start most projects immediately after receipt of a Purchase Order and all required starting materials.

How much protein can I expect to receive?

Protein amounts vary greatly from project to project.  We do not guarantee protein amounts for any given project but we do make every effort to be consistent from batch-to-batch.  If you are unsure about protein yield or have not previously produced a protein, we strongly recommend starting your project with pilot production for yield analysis prior to full scale production.

How much will it cost for 1 mg of purified protein?

The cost per milligram can vary greatly from protein-to-protein due to varying expression levels, type of expression platform, number of purification steps needed, etc.  Therefore, our costs are based on culture volumes and purification schemes rather than milligram amounts of protein.  For recombinant protein production, each quotation will specify a culture volume and purification steps.  You will receive all purified protein produced from that amount of cell culture.

What deliverables will I receive upon completion of my project?

A full technical report or data sheet is delivered for every project. All of the deliverables specified in the quotation, which is typically all of the purified protein produced from the amount of cell culture specified in the quotation.

What are typical turnaround times?

Turnaround times vary depending on the type of project.  Typical turnaround times for recombinant protein production are 4-8 weeks.  The turnaround time for your project will be specified in your quotation prior to project initiation.

Will you sign a confidentiality or material transfer agreement?

Yes. Maintaining customer confidentiality is of utmost importance to us and we are happy to put in place any necessary agreements before discussing or starting your projects. We can start with our 2-way Confidential Disclosure Agreement or Master Service Agreement or we will take under review any documents you provide.
