Prepare a LL-37 testing request
Use the full LL-37 label and supplier specification when describing the sample. The intake code LL37 helps locate this catalogue entry; it does not identify a particular sample or supplier batch.
Also listed as: Cathelicidin LL-37. Confirm the intended form from the specification.
Information to include
For LL-37, provide the labelled amount, supplier lot, sample form and any added solvent or excipients. Explain whether you need identity, quantity, impurity information or a comparison with another report.
- Say whether the product is a defined sequence or a source-defined preparation
- Submit a full sealed vial where endotoxin testing is also requested
- Note any carrier protein or excipient present in the vial
Method and reporting scope
Roughly 1.5 to 5 kDa. Identity rests on a whole-spectrum comparison against reference data rather than a single reading, and related substances sit closer to the parent peak.
Area purity by HPLC-DAD, identity against reference spectra, verifiable COA. Reference availability and sample suitability are confirmed before acceptance. Read the method and reporting information for the techniques in your quote.
Price, timing and submission
The starting panel is $299 CAD. Volume rates, optional fees and tax are shown separately. Standard peptide analysis typically takes 5-10 business days after receipt and acceptance; other scopes are confirmed in the quote.
Wait for the quantity and mailing instructions before shipping. A report describes the sample tested. Testing one vial does not characterize every unit in a batch.
