iFluor® 605 maleimide selectively reacts with thiol group of a biomolecule. It is widely used to label reduced antibodies and other thiol-containing biomolecules such as peptides and thiol-modified oligos. iFluor®605 is a fluorophore from the iFluor® family, which is known for its bright red fluorescence and compatibility with various fluorescence techniques and instruments. When excited with light in the red range (around 580 to 630 nm), iFluor® 605 emits strong red fluorescence. iFluor® 605 can be conjugated to a variety of biomolecules, including antibodies, proteins, nucleic acids, and small molecules, enabling their visualization and tracking in cells and tissues. It is commonly used in fluorescence microscopy, immunohistochemistry, flow cytometry, and other fluorescence-based assays.
