Certificate of Analysis

A certificate of analysis (COA) is the lab document that reports the purity and identity of a specific lot of a peptide. Every Cellaire Labs lot has a COA on file. COAs are provided on request — they are not bundled with every order by default.

A COA for a Cellaire Labs lot reports the following:

• Identity — confirmation that the vial contains the labeled peptide (e.g., by HPLC retention time / mass spec).
• Purity — the percent purity of the lot (typically ≥ 98% for research-grade lyophilized peptides).
• Lot / batch number — the specific lot the COA covers.
• Manufacturer — the originating lab and fill date.
• Test method & date — the analytical method used and when the lot was tested.

Products are sold as-is per the COA for the specific lot. We do not guarantee specific biological outcomes, as these depend on your experimental conditions.

COAs are not shipped with every order by default — this keeps packaging lean and turnaround fast. If you need the COA for a lot, request it in either of these ways:

• At checkout — add a note in the order form requesting the COA, and we’ll include it with your confirmation reply.
• Any time — email info@cellairelabs.com with the product name and lot number, and we’ll send the COA within 1–2 business days.

Every lot’s COA is retained on file for two years and remains available on request throughout that period. If you need a COA for a lot you ordered previously, email info@cellairelabs.com with the product and lot number and we’ll retrieve it.
