Cell-adhesion peptides here are integrin-binding motifs such as linear and cyclic RGD analogues. They are tools for adhesion, coating and targeting research. Cyclic versus linear format changes affinity and should be read from the sequence field, not assumed from the peptide name. Need a PEG spacer or a biotin handle? That is a custom synthesis request. Linear RGD, cRGDfK and biotin-RGD appear as separate listings when the sequence is confirmed. An empty CAS field means the identifier was not verified for the exact form we list; it is not a value of zero. Related reading on cyclization and biotinylation is in the peptide modification cluster. Coating protocols, serum concentration and divalent cations change apparent adhesion more than a small purity difference on a short peptide; match the literature method before you blame the lot. These peptides are research tools and are not supplied as medical devices or targeting drugs.
If the analogue you need is not listed, request custom peptide synthesis with the exact sequence and purity.
