Fluoresceinated peptides
WebBinding of fluoresceinated PEDF to retina cryosections was detected by confocal microscopy. Results: Radioligand-binding assays showed that (125)I-PEDF bound in a specific and saturable fashion to one class of sites on retina membranes (K (d) = 2.5-6.5 nM; maximum binding [B (max)] = 1-48 x 10 (10) sites/retina).

WebJun 20, 1990 · In this study, several methods for controlled labelling of synthetic peptides by the use of fluorescent compounds (fluorescein isothiocyanate and dimethylaminonaphthalene sulfonyl chloride) were investigated. The first reagent yielded … WebThe fluoresceinated peptide, the extended 4 version of Ste5_pep (amino acids 280-321), was present at 10 nM in 20 mM TrisCl pH 8.0, 100 mM NaCl, 5 mM DTT and 1 mg/ml BSA. The resulting binding isotherms were fit to a quadratic binding equation using ProFit 5.1.0 (Quantum Soft) as described elsewhere (S2).
WebThe locked rotaxane exhibited a reduced capacity to transport a fluoresceinated peptide into cells, whereas the unmodified rotaxane efficiently delivers the peptide. Flow cytometry experiments demonstrated that a high percentage of the cells contained the delivered peptide (89−98%), the level of delivery is concentration dependent, and the ...
