BDP 630/650 maleimide
BDP 630/650 maleimide is a thiol reactive, borondipyrromethene based dye tuned to match the far red channel of Cyanine5 fluorophore.JOE azide, 5-isomer
JOE is a chlorinated fluorescein dye which is often used for HEX channel for oligonucleotides. It is less hydrophobic than HEX. This is an azide derivative for сlick chemistryCyanine5.5 hydrazide
Cyanine5.5 hydrazide is a carbonyl reactive NIR dye which is particularly suitable for the labeling of periodate oxidized glycoproteins, i.e. antibodies.General properties
