Application

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 .

Other Notes

Useful blue fluorophore for immunofluorescence, λabs ~350 nm, λem ~440 nm

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

Antibodies coupled to 7-aminocoumarin (AMCA) emit a bright blue fluorescence under ultraviolet (UV) excitation and are therefore ideal for three-color immunofluorescence (IF) with fluorescein (FITC) and phycoerythrin (PE) labeled reagents; however, due to the different absorption spectra, the use of

Dipeptide uptake was studied in primary cultures from rat anterior pituitaries by use of radiolabeled carnosine and the fluorescent dipeptide derivative beta-Ala-Lys-N epsilon-AMCA (AMCA is 7-amino-4-methylcoumarin-3-acetic acid). Fluorescence microscopic studies revealed that the reporter peptide specifically accumulated in the S-100
