When exploring the world of biochemical research, identifying the correct LL-37 peptide CAS number is a fundamental step for any enthusiast or laboratory professional. As someone who has spent considerable time sourcing high-quality peptides for structural analysis and comparative studies, I have learned that precision in nomenclature is just as important as the purity of the compound itself.
The Importance of CAS Identification
The Chemical Abstracts Service (CAS) registry provides a unique identifier for The structure of the antimicrobial human cathelicidin LL-37 substances, which is essential for ensuring you are working with the specific material required. In my experience, the most frequently cited identifier for this cathelicidin-derived antimicrobial peptide is CAS Number: 154947-66-7.
When I look for LL-37 from reliable suppliers, I always cross-reference this CAS registry number 154947-66-7 to ensure consistency. While some databases or specific salt formulations might reference CAS No. 597562-32-8 LL-37(human) | CAS NO.:597562-32-8 or even CAS Number: 2809353-52-2, the standard 154947-66-7 remains the primary point of reference in most academic literature and chemical catalogs.
Structural Insights and Characteristics
LL-37 is a 37-residue, amphipathic peptide that derives its name from the two leucine residues at its LL-37,Human acetateis a 37-residue, amphipathic, cathelicidin-derived antimicrobial peptide, which exhibits a broad spectrum of antimicrobial activity. N-terminus. It is a critical component of the human cationic antimicrobial protein 18 (hCAP18) and corresponds to amino acids 134-170.
Throughout my personal journey with these compounds, I have noted that the molecular formula C205H340N60O53 is a consistent metric used to verify the integrity of the peptide. Whether you are dealing with a Human acetate salt or a trifluoroacetate (TFA) salt, the molecular weight typically hovers around 4493.26 g/mol. Understanding these technical parameters is vital when you are setting up your own inventory.
Practical Considerations for Handling
In my laboratory setup, I prioritize the following when handling this peptide:
* Storage: Always store lyophilized powder at -20°C to maintain stability.
* Purity: I exclusively seek products with a purity of ≥95% (HPLC), as degradation can significantly alter the results of any structural observatio LL-37, Human acetate(154947-66-7 free base) n.
* Identification: Always verify the CAS against the Certificate of Analysis provided by the supplier.
It is fascinating to see how the 15 and 37 in the name relate to the sequence and the NUMBER of residues. Whether you are investigating the structure of this host defense molecule or simply cataloging its properties, knowing that 154947-66-7 is the primary CAS ensures that your work remains reproducible.
Final Reflections
Engaging with these advanced CAS Number, 154947-66-7. PubChem identifier, 16198951. InChiKey, POIUWJQBRNEFGX Spotlight on Human LL-37, an Immunomodulatory Peptide with Promising Cell- Read more biochemical tools requires a level of diligence that goes beyond simple procurement. By focusing on the Antimicrobial peptide LL-37 and its specific identifiers—such as CAS No. 154947-66-7—one can better navigate the landscape of available research materials. I have found that maintaining a clear log of these identifiers, from CAS number 154947-66-7 to the specific CAS number 597562-32-8 for specific salt variants, streamlines the research process and ensures that the LL and 37 components are always handled with the analytical rigor they deserve.
Always LL-37 (human) (trifluoroacetate salt) remember to consult the specific documentation provided with your shipment, as the CAS registry is a dynamic system, and verified data is the backbone of any successful investigation into the aa 134-170 region of the hCAP18 protein.
