Another update from TLR.
Hi Mischa,
After receiving what was by far the best quote for rhDNase1 and remitting the offer to you, bearing I knew it was still likely higher than what was feasible, I subsequently inquired to a colleague of mine who specializes in protein expression optimization as to his thought to creating an optimized system and within that what best cost basis could be garnered. Usually he gets around $4000 upfront for this service, but as we both do many favors for each other and that he strongly supports Project TLR he was willing to explore it at no charge.
Within this, his initial assessment is that an optimized expression system that he can derive should be able to provide a cost basis that is about half of the prior pricing offered.If something of that nature is workable for you I will inform him to proceed. At this point he does not know the actual firm cost basis with certainty, but he seems confident within pursuing it he can get the expression to yield means for production that produces the ability to offer a price that is around that price basis.So, let me know if this seems to be within the area that will be viable. Such would apparently seem to have ability to be under $1/mg basis, which I hope is tenable. If so, he will than work to refine the expression and look to achieve a best cost basis that should hopefully be somewhere in accord with this initial estimated cost basis. Once such is established, from there I will remit the firm offer to you based on such.

The price at the top of the previous page already equates to $0.4/mg, so "under $1/mg" would not necessarily be an improvement. That aside, if it's really half as much as above, then we're talking around $0.2/mg, or about $24/d at the study dose.
I would be in favor of pursuing this source, but we would need to commit to a competent third party lab to do the CoA. We would need a strong authentication protocol involving a homogenization of the mixture, which would detect scams involving real stuff on the top and fake stuff on the bottom. I would let them know up front that we're going to turn the stuff inside out looking for inpurities, such that we require 98% or 99% or whatever. There are plenty of labs out there who could assist.
