Reference standards
for the bench.
The FlexRX research line: lyophilized peptide reference standards, each lot analysed by an independent laboratory and shipped with the certificate that matches it.
For laboratory research use only. Not for human or veterinary use.
The catalog
Opening soon.
We are finalising the first run of reference standards and their certificates of analysis. Every compound is listed here with its lot, its measured purity, and the independent report behind it, and nothing goes up before that report does.
How a lot gets listed
Tested, then listed.
Not the other way round. A lot with no report is a lot you cannot buy here.
-
Identity by mass spectrometry
Each lot is confirmed to be the compound on the label, by MS, at an independent laboratory we do not own.
-
Purity by HPLC
The same lot is assayed by HPLC and its purity is published on the product page as measured, not as targeted.
-
The certificate travels with it
The report is tied to the lot number printed on the vial, so what arrived can always be traced back to what was tested.
Trade accounts
Wholesale &
friends and family.
Approved accounts see a private catalog at account pricing, applied automatically at checkout. Distributors and research organisations order at wholesale; our friends-and-family list gets account pricing with no order minimum.
What does "research use only" mean?
Every product here is a laboratory reference standard supplied solely for in-vitro research. It is not a drug, food, supplement, cosmetic, or medical device, and it is not for human or veterinary use.
Who can order?
Qualified researchers of legal age, ordering on behalf of a research organisation. You confirm both at checkout, and that attestation is recorded with the order.
How do I read the certificate of analysis?
Each COA names the lot, the analytical method, and the measured purity. Match the lot number on your vial to the lot on the report; if they differ, contact us before using the material.
How is it shipped and stored?
Lyophilized powder, shipped with tracking in discreet packaging. Storage and handling conditions are printed on the product page and on the vial.
Is this the same company as myflexrx.com?
Yes. FlexRX Labs is the research-use-only side of FlexRX. The two catalogs are kept entirely separate: consumer products are sold only on myflexrx.com, and nothing on this site is intended for human use.
Known material,
known lot.
An independent report on every lot, tied to the number on the vial. For laboratory research use only.
