Cagrilintide research: overview and resources
What Cagrilintide research material is, how it is characterized, and where to find every specification, method, lot record and reference Cagrilintide Labs publishes about it.
What is Cagrilintide?
Cagrilintide is a 37-residue analog of amylin, the peptide hormone co-secreted with insulin by pancreatic beta cells. It keeps amylin's ring structure, a disulfide bond between cysteines 2 and 7, and its amidated C-terminus, but carries a 20-carbon fatty diacid attached to the N-terminal lysine through a γ-glutamate linker, plus several residue substitutions that reduce amylin's tendency to aggregate. It is designed as a long-acting agonist of the amylin receptors and the calcitonin receptor, which share the calcitonin receptor protein.
Cagrilintide Labs supplies it as a lyophilized powder in 5 mg vials. Each lot is tested by an independent laboratory for HPLC-UV purity, LC-MS identity and net content, and the certificate is published here before sale through Klow.bio.
What is Cagrilintide research material?
Cagrilintide research material is Cagrilintide supplied for laboratory research (C194H312N54O59S2, 4409.07 g/mol) in white lyophilized powder form, sold by lot. Each lot's identity, purity and net content are documented by an independent laboratory in a published certificate of analysis.
How is Cagrilintide characterized?
Three questions are answered for every lot, each by a different method:
- Is it the right compound? LC-MS separates the sample and measures the mass of the main component, confirming it has the molecular weight expected for the compound.
- How much of the sample is that compound? HPLC-UV reports the main peak's share of detected peak area. Current lots: 99.91%.
- How much peptide is in the vial? Net content is measured directly.
Endotoxin (LAL) and microbial DNA (PCR) results are added where those tests are run.
What has not been established
A certificate of analysis describes the specific sample tested on its test date. It does not establish stability afterward, sequence order beyond what mass confirmation shows, results for other lots, or suitability for any particular purpose.
