The naming convention often leads to inquiries about the specific functionality of these components. The Alex Invitrogen™ Pan Cytokeratin Monoclonal Antibody (AE1/ a 488 moiety is a high-performance, green-fluorescent dye known for its photostability and brightness, with a peak 488 nm excitation and emission profile. When this is coupled with a K4 (lysine-rich) sequence, it creates a peptide construct that is highly cationic. These constructs are frequently used for studying cellular uptake, membrane interaction, and molecular assembl Fluorescent Dyes for Secondary Antibodies - Dianova y.
Technical Specifications and Utility
The utility of this conjugate stems from the specific properties of the Alexa488 fluorophore. Unlike traditional dyes, it remains stable across a wide pH range, which is critical when working with K4 sequences that may influence the local microenvironment.
* Fluorophore: Alexa Fluor® 488 (a sulfonated rhodamine derivative).
* Structural Motif: K4, often derived from coiled-coil forming sequences like (KIAALKE)4, which are known to trigger liposomal membrane fusion.
* Reactive Chemistry: The conjugation often utilizes BP Fluor 488 Alkyne or BP Fluor 488 acid to target specific amine or azide groups on the peptide backbone.
Application in Structural Biology and Imaging
My personal experience with these materials highlights their versatility. For example, researchers often use the Biotinylated hLF peptide to transport streptavidin-Alexa 488 into cells, demonstrating how peptide-mediated delivery systems rely on the brightness of the Alexa Fluor® 488 conjugate to visualize intracellular trafficking.
Furthermore, in studies involving K4488 variants or self-assembling cages, the integration of fluorescence allows for real-time tracking. Whether it is Alexa488 nucleic acid encapsulated CPE4-LNP systems or simple peptide labeling, the clarity provided by this dye is unmatched.
