7-Amino-4-methyl-3-coumarinylacetic acid(AMCA) - suitable for fluorescence,90% (HPLC), high purity , CAS No.106562-32-7 1 Citations
Basic Description Synonyms AMCA-H | 7-Amino-4-methylcoumarin-3-acetate | 7-Amino-4-methylcoumarin-3-acetic acid | 2-(7-amino-4-methyl-2-oxochromen-3-yl)acetic acid | A801463 | 2H-1-Benzopyran-3-acetic acid | SCHEMBL72225 | ?AMCA | J-100002 | 7-Amino-4-methyl-3-coumarinylacetic acid Specifications & Purity suitable for fluorescence,90% (HPLC) Shipped In Normal Grade for fluorescence analysis Product Description Non-activated, Amine-reactive, fluorescent probe that can be conjugated to biomolecules. A blue fluorophore useful for immunofluorescence and peptide labeling.AMCA is a useful agent for labeling proteins. Demonstrates a characteristic absorption peak at 345 nm with a fluorescence emission at 440-460 nm (blue region); however, when conjugated with proteins the absorption peak shifts to 355 nm with a fluorescence emission at 440-460 nm. It has a high fluorescence yield with a sufficient Stokes shift (100 nm) and is relatively photostable.Relatively easy to activate and couple to the N-terminal amino group of a peptide resulting in an acid stable amide bond.
Fluorescence: λex 350 nm,λem 433 nm in methanol
