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 [1]. Relatively easy to activate and couple to the N-terminal amino group of a peptide resulting in an acid stable amide bond [2][3].

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

7-Amino-4-methylcoumarin-3-acetic acid (AMCA) has been found to be a useful fluorophore for immunofluorescence. The present study describes a spectrophotometric method for determining the ratio of moles AMCA to moles protein (or the f/p ratio) in an AMCA-conjugated IgG. The concentration

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
